Setodes scutatus n. sp. Yang & Morse (Fig. 9) Diagnosis. This species belongs to the Setodes argentiferus Group (Schmid, 1987), and is most similar to Setodes trilobatus Yang & Morse 1989 from northern China (Shaan-xi) in the following characters: 1) abdominal tergum X is broad, roof-like, its apicomesal portion is distinctively protruded backward beyond two apicolateral ends; 2) each inferior appendage is tri-branched; 3) the phallicata of the phallus is dilated subapically with a beak-like tip. It can be differentiated easily from S. trilobatus in the following characters: 1) the lower branch of each inferior appendage is long, blade like, with its length 1.2 times the length of the ventral margin of segment IX, and with a triangular projection on its dorsal margin in lateral view (the lower branch of each inferior appendage is a short oval lobe, with its length 2/3 the length of the ventral margin of segment IX in S. trilobatus); 2) the parameres are each branched subapically into two decurved hooks (not branched subapically in S. trilobatus); 3) the mesal branch of each inferior appendage is stout, with its apex strongly produced mesad into a triangular process and with the mesal end acute in caudal view, (the mesal branch is a narrow band, its apex with the mesal process slender in caudal view in S. trilobatus); 4) the paired basomedian lobes of tergum X are about as broad as the preanal appendages and with truncate apices in dorsal view (much smaller and subtriangular in S. trilobatus); and 5) the phallus has a narrow crescent phallobase (the phallobase is semicircular in S. trilobatus). Adult. Length of each male forewing 6.5���7.0 mm (n = 5). Specimen in alcohol generally pale yellow, forewings without evidence of golden spots or striae, covered with concolorous fine hair. Wing venation typical for genus, cell R3 (between veins R3 and R 4+5) almost as long as fork of MA and MP (between veins M1+2 and M3+4), tips of fore- and hind wings acute (Figs. 9F, 9H). Male genitalia. Segment IX longitudinally short dorsally, forming narrow transverse band (Fig. 9A). Preanal appendages large, setose mounds, positioned beside basomedian lobes of tergum X in dorsal view (Fig. 9B). Tergum X long and broad, roof-like with prominent median ridge (Fig. 9A); in dorsal view 1.5 times as long as wide, basal median lobes each with truncate apex and about as broad as preanal appendage (Fig. 9B), apicomesal end distinctively protruding backward beyond two apicolateral ends, forming trilobed apex (Fig. 9B). Inferior appendages each trifurcate, lower branch of appendage elongate blade-like, 1.2 times as long as ventral margin of segment IX and with triangular projection on midlength of dorsal margin in lateral view (Fig. 9A lower arrow); mesal branch short, 1/2 as long as upper branch of inferior appendage, with apex blunt in lateral view but in caudal or dorsal views strongly produced mesad into triangular process with acute mesal end (Figs. 9A middle arrow, 9A-a); small, setose papilla visible at base in caudal view (Fig. 9 C-a arrow); upper branch slender and sinuate, 2/3 as long as lower branch of inferior appendage, with apex bearing two long setae (Figs. 9A upper arrow, 9C-a.). Phallus with narrow crescentic phallobase; pair of parameres stout, originating above phallobase, curved caudad then sloping caudoventrad, each branched subapically into two decurved hooks with inner hook nearly transparent; phallicata strongly arched, slender, parallel sided in basal half in lateral view, with distal half expanded dorsolaterally into two broad subapical lobes, with abruptly narrowed beak-like apex directed downward (Fig. 9D).

Ceraclea (Ceraclea) megalophyllon sp. n. Yang & Morse (Figs. 1 A–1D, 4A–4C) Diagnosis. The male adult of this new species somewhat resembles that of Ceraclea (C.) nigronervosa (Retzius, 1783) which is widely distributed in the Palearctic and Nearctic Biogeographic Regions. Both species possess a large, hood-like tergum X, especially with the caudal portion divided into three lobes, of which the large mesal lobe is much longer than the lateral lobes. The general shape of the inferior appendages and the phallus are also of a similar pattern. It differs from that of C. nigronervosa by the following characters: (1) tergum X is extremely broad, with its median caudal lobe slightly longer than, and 1.5 times as broad as its lateral caudal lobes and all three lobes are visible in dorsal view (the median caudal lobe is much longer than the lateral caudal lobes and the lateral lobes are visible only in lateral view in C. nigronervosa); (2) the basoventral lobe of each inferior appendage is short, stub-like and has two short, stout setae apically (this lobe is represented as a blunt triangular projection in lateral view and without stout setae apically in C. nigronervosa,). The broad median caudal lobe of male tergum X of this new species is unique among all presently known species in subgenus Ceraclea. The female of the new species is also similar to that of C. nigronervosa by lamallae having distinctive membranous regions at the bases of the lamellae, internal gonopod VIII (i.gon.VIII) composed of a broad semicircular lobe apicoventrally and a small tongue-shaped lobe apicodorsally. However, it can be distinguished from that of C. nigronervosa by the following characters: (1) the pair of gonopod plates (e.gon.VIII + e.gon.IX) are closely approximate on the meson anteriorly and divergent posteriorly, forming two sub-truncate lobes (the pair of gonopod plates are distantly situated, each forming an elliptical lobe in C. nigronervosa), (2) the internal gonopod VIII is semicircular apicoventrally, much broader than the paired gonopod plates, with apex extending far beyond the tips of the gonopod plates (the internal gonopod VIII is almost identical with the paired gonopod plates in shape and with its apex scarcely surpassing the tips of the gonopod plates in C. nigronervosa). Adult. Length of each male forewing 8.7 mm (n = 1), of each female forewing 8.0 mm (n = 1). Type specimens preserved in alcohol for 7 years such that the color is faded and the wing and body hairs lacking. Head, basal two segments of antennae, and thorax generally brown.Wings brown, covered with fine light brown hair, wing venation of male and female typical for genus (e.g., Morse 1975, figs. 27, 28). Male genitalia. Preanal appendages broadly oval, not fused with each other basally, widely divergent in dorsal view (Fig. 1B), elongate-triangular lateral and dorsal views (Figs. 1A, 1B). Tergum X large, hood-like with caudal portion strongly upturned (Fig. 1A) and divided into three large lobes, median caudal lobe about as long as and 1.5 times as broad as lateral caudal lobes in dorsal view (Fig. 1B). Basoventral lobe of each inferior appendage short, stub-like, truncate at apex, with two short stout setae apically (Figs. 1A arrow, 1C arrow); main body of inferior appendage erect in lateral view; phallic guide with blunt right angle near base, setose; harpago at least 3/4 as long as subapicodorsal lobe, with triangular apex directed mesad in caudal view (Fig. 1C). Phallobase projecting both dorsally and ventrally with dorsal projection about 2 times as long as ventral projection, 2 long paramere spines slender and nearly straight (Fig. 1D). Female genitalia. Segment IX with anterodorsal region (IXa) ending posteriorly in small, paired papillae, mostly fused with each other mesally; preanal appendages (IXb) transverse, setose bands, and separated mesally by papillae at apex of IXa (Fig. 4B); IXc forming transverse plate (Figs. 4A, 4B) with shallow apical incision in dorsal view; lamellae (IXd) short sclerotized lobes each with posteroventral margin nearly straight, shallowly excised at 1/3 distance from tip in lateral view (Fig. 4A); membranous regions at bases of lamellae distinctive. Pair of deep concavities (“longitudinal grooves” of Carnagey & Morse 2006) on either side of conical genitalia just above gonopod plates (Fig. 4A arrow), visible also in dorsal and ventral views (Figs. 4B arrow, 4C arrow). Pair of gonopod plates (e.gon.VIII + e.gon.IX) closely approximate or fused on meson anteriorly, without intervening median plate, abruptly divergent and forming two broadly sub-truncate lobes beyond middle (Fig. 4C); dorsal internal gonopod IX (d.i.gon.IX) large, highly scletotized and with deep V-shaped apicomesal excision in dorsal view (Fig. 4B); internal gonopod VIII (i.gon.VIII) composed of broad semicircular lobe apicoventrally and small tongue shaped lobe apicodorsally (Fig. 4C). Spermathecal sclerite nearly circular, chufa-tuber-shaped, about as wide as long (Fig. 4C). Holotype male.

Oecetis (Pleurograpta) spinellosa sp. n. Yang & Hu (Figs. 6, 7D, 7F) Diagnosis. This new species belongs to the Oecetis (Pleurograpta) testacea Group in which the males have the last abdominal tergites with “Maschenplatten” (Malicky 2005, or “honeycomb reticulation areas” of Yang & Morse 2000). The male resembles those of Oe. (Pl.) t. testacea (Curtis 1834) (widely distributed in the Palearctic Region), Oecetis (Pl.) testacea kumanskii Yang & Morse 2000 (Korea), Oe. (Pl.) tsudai Fischer 1970 (Japan), and Oe. (Pl.) palamedes Malicky 2005 (Indonesia-Sumatra) in the distribution of honeycomb reticulation areas and the general shape of the genitalia. This new species, from Oriental China, differs from them in the following characters: 1) The posterolateral corners of the upper half of segment IX are not protruded backward, but instead each forms a vertical, elliptical region with its height 2 times its longitudinal length and densely covered with minute spines and setae (Fig. 6A upper arrow; the posterodorsal corners of segment IX each protrudes in an acute triangle with minute spines in Oe. testacea kumanskii and protrudes in a rounded lobe almost without spines in Oe. t. testacea and Oe. palamedes); 2) the dorsal branch of each inferior appendage slopes backward forming a 60° angle with the basoventral branch and the apex of the dorsal branch is smooth, acute, and pointed upward (the dorsal branch is straight and points upward forming at least a 100° angle with the basoventral branch and the apex of the branch bears several stout teeth and is curved mesad in Oe. t. testacea, Oe. testacea kumanskii, Oe. tsudai, and Oe. palamedes); 3) the basoventral branch of each inferior appendage has a distinctive small mesodorsal seta-bearing chalaza (Fig. 6A lower arrow; each inferior appendage is without a mesodorsal chalaza in the above four species); 4) the phallus has two long, identical paramere spines (the phallus has one long paramere spine and three short spines in Oe. t. testacea and Oe. testacea kumanskii, one long and one shorter spine in Oe. palamedes; phallic spines are unknown in Oe. tsudai). Tergum X is much longer in Oe. palamedes than in the other four species and the preanal appendages are not evident. The females of Oe. tsudai and Oe. palamedes are unknown. The females of Oe. t. testacea and Oe. testacea kumanskii were illustrated by Kumanski (1991). The female of the new species can be distinguished from those of Oe. t. testacea and Oe. testacea kumanskii by the following characters: 1) The lamellae are well sclerotized, each quadrate in its basal half with the distal half narrowing to a finger-like process in lateral view (Fig. 7D; each lamella is a short or elongate lobe without a slender finger-like apical process in Oe. t. testacea and Oe. testacea kumanskii); 2) the gonopod plate is broader posteriorly and with a pair of rounded posterolateral corners in ventral view (Fig. 7F; the gonopod plate is nearly circular, broadest at midlength, narrowed and rounded anteriorly and posteriorly in Oe. t. testacea; a ventral view of Oe. testacea kumanskii is not available). Adult. Length of each male forewing 5.7–6.7 mm (n = 3), of each female forewing 6.0– 6.5 mm (n = 5). Head and thorax yellowish brown. Forewings hyaline, faintly yellowish; forks of veins and anastomosis lightly shaded with fuscous, veins of anastomosis aligned (Fig. 6F). Thick honeycomb reticulation areas covering terga V, VI, and VII in pairs, and an undivided honeycomb reticulation are covering tergum VIII. Male genitalia. Segment IX longitudinally long ventrally, very short dorsally, anterior margins of pleura IX strongly produced forward in lateral view, posterodorsal corners each forming vertical, elliptical concavity with its height 2 times its longitudinal length and densely covered with minute spines and setae (Fig. 6A upper arrow, 6B pos.cr.IX); preanal appendages slender, divergent, curved slightly downward, gradually slightly thicker apically. Upper part of tergum X (Fig. 6B up.pt.X) single, rod-like, lower part of tergum X (Fig. 6B lo.pt.X) composed of pair of flat, semimembranous lobes, each bearing few setae apically. Dorsal branch of each inferior appendage sloping backward forming 60° angle with basoventral branch, very broad in basal half with distal half gradually reducing to smooth, acute, triangular tip pointed upward (Fig. 6A d.br.), in caudal view with basomesal region of dorsal branch set with many minute spines (Fig. 6C arrow); basoventral branches of inferior appendages divergent, each with distal half finger-like and with blunt tip in ventral view (Fig. 6 C-bv), in lateral view each with small triangular seta-bearing chalaza on upper surface near middle (Fig. 6A lower arrow, 6C-bv arrow). Phallus asymmetrical, right piece of phallobase tall, well developed, with left piece much lower, its dorsal margin expanded outward, forming narrow longitudinal ridge (arrow); two long paramere spines essentially identical (Fig. 6D). Female genitalia. Pleural region of segment IX produced outward, appearing as subvertical ridge in lateral view (Fig. 7D left arrow); in ventral view, each side forming large plate, rounded at outer margin with median portion moderately concave (Fig. 7F). Dorsum IXc and segment X forming short anal tube, its bottom semimembranous with U-shaped cleft apically (Fig. 7F). Lamellae well sclerotized, broadly quadrate in basal half, each with its dorsolateral margin forming round, setose ridge (Fig. 7D right arrow), distal half reduced to finger-like process in lateral view (Fig. 7D). Posterior margin of gonopod plate broader than anterior margin and slightly sinuate in ventral view (Fig. 7F). Internal part of gonopod VIII semimembranous, with its exposed portion short and rectangular in ventral view and triangular in lateral view (Figs. 7D, 7F). Diagonal striations on lower regions of pleura (Fig. 7F arrow). Holotype. Male; CHINA: An-hui Province, Qi-men County, Li-xi Village, Qi-yang-keng, N29.52, E117.42, alt. 360 m, 14 Aug. 2001, Coll.

Phraepsyche acuminata, n. sp. Yang & Morse (Fig. 10) So far Phraepsyche consists of only 4 species from Southeast Asia, Phraepsyche danaos Malicky & Sompong 2000 (in Malicky et al. 2000) from Thailand, Ph. epha Malicky 2008 and Ph. pectinata Ol��h & Johanson 2010 from Vietnam, and Ph. yitungshana Ol��h & Johanson 2010 from Hong Kong, China. The diagnostic characters for this genus have been given by Ol��h & Johanson 2010. Diagnosis. This species is most similar to Ph. epha from Vietnam in the wing venation, the distribution of the hair belt on the forewings, the wing fold pattern of the hind wings, and the similar general shape of male genitalia. The new species is distinguished from Ph. epha in the following characters: 1) the longitudinal hair belt on each forewing extends from the wing base (base of Cu), crosses over the anastomosis, then bends upward between R5 and the MA area to a blunt wing tip (in Ph. epha the longitudinal hair belt on each forewing is distributed only from the anastomosis to an acute wing tip); 2) the anal margins of the hind wings are sinuate and bear long marginal hairs and a row of dark, robust setae directed upward (in Ph. epha, anal margins of hind wings are not sinuate and without the additional row of dark, robust setae); 3) inferior appendages of the male genitalia have harpagones that are slender and smooth, goat-horn-like, each with its distal 1/3 sharpened to an acute apex and turned downward and mesad, (in Ph. epha, harpagones are thick and bearing many tiny setae, each evenly tapered and straight to blunt apex); and 4) the phallicata is about 2/5 as long as the phallobase and separated from it by a dorsal indentation and a ventral constriction in lateral view (dorsal and ventral margins parallel in Ph. epha). Adult. Length of each male forewing 6.2���8.2 mm (n = 3). Specimens in alcohol for more than 10 years generally yellowish brown. Head, maxillary palps each 5-segmented, first to third segments fringed with short setae, fourth and fifth segments almost bare and equal in length (10E). Scape of each antenna almost as long as head, with anterior surface concave, densely filled with hairs (Fig. 10I); pectination on flagellum from first to twelfth segments, first pectinal branch very short, only 1/2 as long as any others, all other branches subequally long. Wings translucent yellowish brown, venation of fore- and hind wings somewhat similar to that of Ph. epha, with Forks I, II, and V in forewings and Fork V in hind wings, but longitudinal hair belt on each forewing from wing base to wing tip distinctive, densely bearing fine hairs and scale hairs from base of Cu to anastomosis, then bending upward between R5 and MA area to blunt wing tip, membrane of belt area concave below wing surface and with paler color than rest of wing (Fig. 10F). Hair belt on each hind wing between stems of R and M in basal half then at anatamosis crossing membrane at base of cell R5 to fill cell R3 between apparent R2+3 and R4+5; in addition two wing folds located anterior of stem of M and anterior of basal half of Cu2; anal margin sinuate, fringed with ordinary marginal hairs and distinctive row of dark robust setae directed upward (Fig. 10H). Long, digitate projection arising from posterior margin of abdominal sternum VI, densely covered with short, fine setae, with its apex reaching posterior margin of sternum VII (Fig. 10G). Male genitalia. In lateral view (Fig. 10A), greatest longitudinal length of segment IX 1/3 height, its anterior margins protruding forward in 80�� angle at 1/4 distance from ventral margin. Distal half of tergum X, in dorsal view, forming pair of triangular lobes, each with 4���5 stout setae on outer margin and with its medial margins parallel to each other; in addition, setose medial hump present mesally at bases of triangular lobes (Fig. 10B) prominent in lateral view (Figs. 10A, 10 B-a). Preanal appendages as long as segment IX with rounded apices in lateral view. Inferior appendages with coxopodite stout, erect, with distal half slightly curved backward (Fig. 10A), length between base of appendage and subapical lobe about 3 times its width in ventral view and subapicodorsal lobe curving mesad, about half as broad as mean width of coxopodite (Fig. 10C). Harpagones long, goat-horn-like, stout in basal 1/4 with distal 1/3 sharp and turned downward and mesad (Figs. 10 A���10C), each arising from distal 1/3 of appendage in ventral view (Fig. 10C). Phallus about as long as inferior appendages, tubular phallobase nearly straight, phallicata appearing as continuation of sclerotized phallobase, about 2/5 length of phallobase and separated from it by dorsal indentation and ventral constriction, then narrowing to blunt triangular apex in lateral view (Fig. 10D); in ventral view, phallicata widely opened with endotheca visible (Fig. 10 Da); ejaculatory duct with conspicuous twist at 1/2 length of phallus; phallotremal sclerite appearing as circular ring in lateral and ventral views (Figs. 10D, 10 D-a).

Ceraclea (Athripsodina) aerumnula sp. n. Yang & Morse (Figs. 2 A���2D) Diagnosis. This new species is somewhat similar to C. (A.) excisa (Morton 1904), C. (A.) shuotsuensis (Tsuda 1942), and C. (A.) globosa Yang & Morse 1988 from northeastern China (Yang & Morse 2000) in the following character of the male genitalia: Inferior appendages each with well-developed phallic guide, but it differs from those in having the phallic guide broadly trapezoidal in caudal view (triangular in C. excisa, C. shuotsuensis, and C. globosa). On the other hand, the new species is somewhat similar to C. (A.) emeiensis Yang & Tian 1987 from central China, and C. (A.) brachyacantha Yang & Tian 1987 from southeastern China in the following character: Tergum X is slender with its distal half highly elevated in lateral view. However, it differs from those in having the basoventral lobe of each inferior appendage bearing a long, stick like black rod apically (lacking from the basovental lobe in C. emeiensis, a very short apical spine in C. brachyacantha); and in the phallus has only one stout, rod-like paramere spine with the distal 1/3 twisted to the left, which is different from all of the five species above. Adult. Length of each male forewing 7.0��� 7.5 mm (n = 5), of each female forewing 6.0 mm (n = 2). Most type specimens teneral, generally pale; only holotype non-teneral, fully mature. Head and thorax brownish-black, antennae light brown. Wings dark brown, covered with concolorous fine hair; with traces of few small white spots sparsely scattered on distal half of each forewing near anterior margin. Male genitalia. Segment IX basically rectangular, abruptly shorter longitudinally on dorsal 1/ 3 in lateral view (Fig. 2A), forming narrow transverse band projecting caudad in arch in dorsal view.

Ceraclea (Athripsodina) lamellata sp. n. Yang & Hu (Figs. 3 A���3D, 4D���4F) Diagnosis. This new species is among the members of the Ceraclea (Athripsodina) riparia Group all sharing the character of the retracted paramere spines of the male phallus being aligned, such that the posterior end of the basal spine touches the anterior end of the distal spine. The male of this new species is most similar to that of C. (A.) nankingensis Yang & Morse 1988 from Jiangsu. It can be distinguished from the latter in male genitalia by the following characters: (1) The basoventral lobe of each inferior appendage has two stout apical spines and the basal half of the lobe is expanded ventromesad in a very thin, semicircular plate (there is only one stout spine apically and the basoventral branch does not have a thin semicircular plate in C. nankingensis), (2) the anterodorsal end of the phal- lobase is conspicuously expanded such that the phallic foramen is positioned on the ventral surface near the middle (the phallic foramen is positioned anteriorly in C. nankingensis). The female of the new species is most similar to that of C. (A.) yangi (Mosely, 1942), keying to that species in the work by Yang & Morse (1988). It differs from the latter by the following characters: (1) the preanal appendages (IXb) are transversely much narrower in the new species; and (2) tergum IXc is about 1/3 as long as the lamellae (IXd) in lateral view (half as long as the lamellae in C. yangi). Adult. Length of each male forewing 5.2���5.5 mm (n = 5), of each female forewing 4.0��� 4.5 mm (n = 5). Head and thorax reddish brown. Forewings yellowish brown, with white and brownish hairs intermixed. Dorsum of abdominal segments II���IV dark brown. Male genitalia. Preanal appendages oval, fused on basal 1/ 3 in dorsal view. Tergum X broad and triangular in basal half, 1.3 times as long as preanal appendages in dorsal view, with distal portion narrow and parallel-sided to rounded apex (Fig. 3B), lateral processes of X slender, arising near base, extending not quite to apex of segment X (Fig. 3A). Basoventral lobe of each inferior appendage forming 30��angle to main body (Fig. 3A), with its basal half expanded ventromesad in thin, semi-circular plate conspicuous in both lateral and ventral views (Figs. 3A arrow, 3C arrow), and lobe with two short spines apically; in ventral view, these two apical spines appearing appressed togeth- er as single projection (Fig. 3C); mesal ridges of main body inconspicuous except for patch of stiff hairs, just as in C. nankingensis (Yang & Morse 1988 p. 56, fig. 16C), but not visible in our Fig. 3C. Phallobase conspicuously expanded anteriorly, about 2.5 times as long as wide, phallic foramen positioned on ventral surface nearly half distance from anterior end; retracted two stout paramere spines arranged in line, anterior spine curved in ventral arc with its basal end touching anterior walls of endophallic membranes (Fig, 3D left arrow) and distal end connecting with base of posterior spine (Fig. 3D right arrow), latter strongly curved ventrad at 1/3 distance from base (Fig. 3D). Female genitalia. Tergum IXa thick and rounded in lateral view but small and nearly acute with pair of apicomesal papillae in dorsal view (Figs. 4D, 4E). Preanal appendages (IXb) transversely broad but longitudinally very short, mostly fused with segment IX (Figs. 4D, 4E). Dorsal apex of segment IX (IXc) acute in lateral view, undivided and ogival in dorsal view (Figs. 4D, 4E). Lamellae (IXd) large, about as long as segment IX in lateral view (Fig. 4D), especially setose on ventral surfaces (Fig. 4F). Gonopod plates separated by membrane mesally, with few longitudinal striae laterally, each plate with 2 apical projections, with mesal one (e.gon.VIII) short, semicircular, and lateral one (e.gon.IX) large, elliptical, visible in dorsal and ventral views (Figs. 4E, 4F). Spermathecal sclerite sub-rhomboid, about 1.5 times long as median width with anterior end extending to middle of segment VIII, and with side margins sinuate (Fig. 4F). Holotype male.

Setodes charax Yang & Morse, n. sp. (Fig. 8) Diagnosis. This new species belongs to Setodes dhanavriddha Group (Schmid 1987), to which two additional species have been included: St. laertes Malicky & Chantaramongkol 2006 from Nepal and St. lailaps Malicky & Chantaramongkol 2006 from Thailand. The male genitalia of our new species have the form of those of St. antardhana Schmid 1987, St. gherni Schmid 1987, and St. divyarupa Schmid 1987 from India in the following characters: 1) The long lateral branches of segment X are positioned at 1/4 distance below the dorsal margin of segment IX, such that the dorsum of IX seems highly elevated in lateral view; 2) the lateral branches of X are serrate subapically and are usually fringed with long hair; and 3) the phallic parameres are very long and slender, arched parallel to the phallicata. However, the male genitalia of St. charax differ from those of these three species in the following characters: 1) The lateral branches of tergum X each is forked apically in lateral or dorsal views (not branched at the apex in St. antardhana and St. gherni, with the apex branched into three stout teeth in St. divyarupa); 2) the phallicata is slen- der, trough-shaped, and the dorsal ridges are not expanded laterally for reception of the parameres (the dorsal ridges are expanded for reception of the parameres in the above three species); 3) the parameres are very long and slender, each deeply divided at 1/4 length into two subparallel branches (the parameres are not divided in St. antardhana, St. gherni, and St. divyarupa). Adult. Length of each male forewing 6.0– 6.5 mm (n = 2). Specimens in alcohol generally pale, forewings pale brown, covered with concolorous fine hair. Wing venation similar to Setodes scutatus n. sp. (Figs. 9F, 9H), except hind wing cell M1+2 short, such that cell R3 at least 1.5 times longer than cell M1+2 (Fig. 8F arrows), tips of fore- and hind wings acute. Male genitalia. Segment IX anterior margin concave and strongly reduced subdorsally at 4/5 height and posterior margin deeply indented at bases of lateral branches of segment X (Figs. 8A, 8B), in dorsal view with mesal 3/5 forming trapezoid plate (Fig. 8B), and with pair of setal warts near its anterior margin (Figs. 8A, 8B); broadly rectangular and nearly 2/3 as long as wide in ventral view (Fig. 8C). Preanal appendages apparently absent. Tergum X represented by pair of highly sclerotized lateral branches, each arising at 1/4 distance from dorsal margin of segment IX, fringed with long hair near midlength, and with forked apex (Figs. 8A, 8B); in dorsal view, branches slightly asymmetrical in respect to one another, stout at basal 1/2, each gradually narrowing to forked and subapically toothed apex (Fig. 8B). Inferior appendages short and set vertically, generally kidney shaped in lateral view; each with three branches positioned on dorsal half, two of them located on inner posterior margin of appendage, upper one finger-like with acute tip and lower one rod-like with truncate tip; longest, third branch arising between the other two in lateral view, slender, set on outer posterior margin near top; in addition, below these branches near middle of appendage, stout seta arising from long chaza on outer posterior margin, posterolateral margin below chalaza sinuous and with few setae (Fig. 8A). Phallobase plate-like, phallicata long, trough-like; arched about 90° in middle, with basal 1/2 about 2 times as broad as distal 1/3, with pair of small, triangular phallotremal sclerites embedded subapically in endophallic membranes; pair of parameres slender, almost as long as phallicata, each deeply divided into two branches proximate to each other in basal 3/4, divergent slightly near apices (Figs. 8B, 8D).

Oecetis (Pleurograpta) spinellosa sp. n. Yang & Hu (Figs. 6, 7D, 7F) Diagnosis. This new species belongs to the Oecetis (Pleurograpta) testacea Group in which the males have the last abdominal tergites with ���Maschenplatten��� (Malicky 2005, or ���honeycomb reticulation areas��� of Yang & Morse 2000). The male resembles those of Oe. (Pl.) t. testacea (Curtis 1834) (widely distributed in the Palearctic Region), Oecetis (Pl.) testacea kumanskii Yang & Morse 2000 (Korea), Oe. (Pl.) tsudai Fischer 1970 (Japan), and Oe. (Pl.) palamedes Malicky 2005 (Indonesia-Sumatra) in the distribution of honeycomb reticulation areas and the general shape of the genitalia. This new species, from Oriental China, differs from them in the following characters: 1) The posterolateral corners of the upper half of segment IX are not protruded backward, but instead each forms a vertical, elliptical region with its height 2 times its longitudinal length and densely covered with minute spines and setae (Fig. 6A upper arrow; the posterodorsal corners of segment IX each protrudes in an acute triangle with minute spines in Oe. testacea kumanskii and protrudes in a rounded lobe almost without spines in Oe. t. testacea and Oe. palamedes); 2) the dorsal branch of each inferior appendage slopes backward forming a 60�� angle with the basoventral branch and the apex of the dorsal branch is smooth, acute, and pointed upward (the dorsal branch is straight and points upward forming at least a 100�� angle with the basoventral branch and the apex of the branch bears several stout teeth and is curved mesad in Oe. t. testacea, Oe. testacea kumanskii, Oe. tsudai, and Oe. palamedes); 3) the basoventral branch of each inferior appendage has a distinctive small mesodorsal seta-bearing chalaza (Fig. 6A lower arrow; each inferior appendage is without a mesodorsal chalaza in the above four species); 4) the phallus has two long, identical paramere spines (the phallus has one long paramere spine and three short spines in Oe. t. testacea and Oe. testacea kumanskii, one long and one shorter spine in Oe. palamedes; phallic spines are unknown in Oe. tsudai). Tergum X is much longer in Oe. palamedes than in the other four species and the preanal appendages are not evident. The females of Oe. tsudai and Oe. palamedes are unknown. The females of Oe. t. testacea and Oe. testacea kumanskii were illustrated by Kumanski (1991). The female of the new species can be distinguished from those of Oe. t. testacea and Oe. testacea kumanskii by the following characters: 1) The lamellae are well sclerotized, each quadrate in its basal half with the distal half narrowing to a finger-like process in lateral view (Fig. 7D; each lamella is a short or elongate lobe without a slender finger-like apical process in Oe. t. testacea and Oe. testacea kumanskii); 2) the gonopod plate is broader posteriorly and with a pair of rounded posterolateral corners in ventral view (Fig. 7F; the gonopod plate is nearly circular, broadest at midlength, narrowed and rounded anteriorly and posteriorly in Oe. t. testacea; a ventral view of Oe. testacea kumanskii is not available). Adult. Length of each male forewing 5.7���6.7 mm (n = 3), of each female forewing 6.0��� 6.5 mm (n = 5). Head and thorax yellowish brown. Forewings hyaline, faintly yellowish; forks of veins and anastomosis lightly shaded with fuscous, veins of anastomosis aligned (Fig. 6F). Thick honeycomb reticulation areas covering terga V, VI, and VII in pairs, and an undivided honeycomb reticulation are covering tergum VIII. Male genitalia. Segment IX longitudinally long ventrally, very short dorsally, anterior margins of pleura IX strongly produced forward in lateral view, posterodorsal corners each forming vertical, elliptical concavity with its height 2 times its longitudinal length and densely covered with minute spines and setae (Fig. 6A upper arrow, 6B pos.cr.IX); preanal appendages slender, divergent, curved slightly downward, gradually slightly thicker apically. Upper part of tergum X (Fig. 6B up.pt.X) single, rod-like, lower part of tergum X (Fig. 6B lo.pt.X) composed of pair of flat, semimembranous lobes, each bearing few setae apically. Dorsal branch of each inferior appendage sloping backward forming 60�� angle with basoventral branch, very broad in basal half with distal half gradually reducing to smooth, acute, triangular tip pointed upward (Fig. 6A d.br.), in caudal view with basomesal region of dorsal branch set with many minute spines (Fig. 6C arrow); basoventral branches of inferior appendages divergent, each with distal half finger-like and with blunt tip in ventral view (Fig. 6 C-bv), in lateral view each with small triangular seta-bearing chalaza on upper surface near middle (Fig. 6A lower arrow, 6C-bv arrow). Phallus asymmetrical, right piece of phallobase tall, well developed, with left piece much lower, its dorsal margin expanded outward, forming narrow longitudinal ridge (arrow); two long paramere spines essentially identical (Fig. 6D). Female genitalia. Pleural region of segment IX produced outward, appearing as subvertical ridge in lateral view (Fig. 7D left arrow); in ventral view, each side forming large plate, rounded at outer margin with median portion moderately concave (Fig. 7F). Dorsum IXc and segment X forming short anal tube, its bottom semimembranous with U-shaped cleft apically (Fig. 7F). Lamellae well sclerotized, broadly quadrate in basal half, each with its dorsolateral margin forming round, setose ridge (Fig. 7D right arrow), distal half reduced to finger-like process in lateral view (Fig. 7D). Posterior margin of gonopod plate broader than anterior margin and slightly sinuate in ventral view (Fig. 7F). Internal part of gonopod VIII semimembranous, with its exposed portion short and rectangular in ventral view and triangular in lateral view (Figs. 7D, 7F).

Ceraclea (Ceraclea) megalophyllon sp. n. Yang & Morse (Figs. 1 A���1D, 4A���4C) Diagnosis. The male adult of this new species somewhat resembles that of Ceraclea (C.) nigronervosa (Retzius, 1783) which is widely distributed in the Palearctic and Nearctic Biogeographic Regions. Both species possess a large, hood-like tergum X, especially with the caudal portion divided into three lobes, of which the large mesal lobe is much longer than the lateral lobes. The general shape of the inferior appendages and the phallus are also of a similar pattern. It differs from that of C. nigronervosa by the following characters: (1) tergum X is extremely broad, with its median caudal lobe slightly longer than, and 1.5 times as broad as its lateral caudal lobes and all three lobes are visible in dorsal view (the median caudal lobe is much longer than the lateral caudal lobes and the lateral lobes are visible only in lateral view in C. nigronervosa); (2) the basoventral lobe of each inferior appendage is short, stub-like and has two short, stout setae apically (this lobe is represented as a blunt triangular projection in lateral view and without stout setae apically in C. nigronervosa,). The broad median caudal lobe of male tergum X of this new species is unique among all presently known species in subgenus Ceraclea. The female of the new species is also similar to that of C. nigronervosa by lamallae having distinctive membranous regions at the bases of the lamellae, internal gonopod VIII (i.gon.VIII) composed of a broad semicircular lobe apicoventrally and a small tongue-shaped lobe apicodorsally. However, it can be distinguished from that of C. nigronervosa by the following characters: (1) the pair of gonopod plates (e.gon.VIII + e.gon.IX) are closely approximate on the meson anteriorly and divergent posteriorly, forming two sub-truncate lobes (the pair of gonopod plates are distantly situated, each forming an elliptical lobe in C. nigronervosa), (2) the internal gonopod VIII is semicircular apicoventrally, much broader than the paired gonopod plates, with apex extending far beyond the tips of the gonopod plates (the internal gonopod VIII is almost identical with the paired gonopod plates in shape and with its apex scarcely surpassing the tips of the gonopod plates in C. nigronervosa). Adult. Length of each male forewing 8.7 mm (n = 1), of each female forewing 8.0 mm (n = 1). Type specimens preserved in alcohol for 7 years such that the color is faded and the wing and body hairs lacking. Head, basal two segments of antennae, and thorax generally brown.Wings brown, covered with fine light brown hair, wing venation of male and female typical for genus (e.g., Morse 1975, figs. 27, 28). Male genitalia. Preanal appendages broadly oval, not fused with each other basally, widely divergent in dorsal view (Fig. 1B), elongate-triangular lateral and dorsal views (Figs. 1A, 1B). Tergum X large, hood-like with caudal portion strongly upturned (Fig. 1A) and divided into three large lobes, median caudal lobe about as long as and 1.5 times as broad as lateral caudal lobes in dorsal view (Fig. 1B). Basoventral lobe of each inferior appendage short, stub-like, truncate at apex, with two short stout setae apically (Figs. 1A arrow, 1C arrow); main body of inferior appendage erect in lateral view; phallic guide with blunt right angle near base, setose; harpago at least 3/4 as long as subapicodorsal lobe, with triangular apex directed mesad in caudal view (Fig. 1C). Phallobase projecting both dorsally and ventrally with dorsal projection about 2 times as long as ventral projection, 2 long paramere spines slender and nearly straight (Fig. 1D). Female genitalia. Segment IX with anterodorsal region (IXa) ending posteriorly in small, paired papillae, mostly fused with each other mesally; preanal appendages (IXb) transverse, setose bands, and separated mesally by papillae at apex of IXa (Fig. 4B); IXc forming transverse plate (Figs. 4A, 4B) with shallow apical incision in dorsal view; lamellae (IXd) short sclerotized lobes each with posteroventral margin nearly straight, shallowly excised at 1/3 distance from tip in lateral view (Fig. 4A); membranous regions at bases of lamellae distinctive. Pair of deep concavities (���longitudinal grooves��� of Carnagey & Morse 2006) on either side of conical genitalia just above gonopod plates (Fig. 4A arrow), visible also in dorsal and ventral views (Figs. 4B arrow, 4C arrow). Pair of gonopod plates (e.gon.VIII + e.gon.IX) closely approximate or fused on meson anteriorly, without intervening median plate, abruptly divergent and forming two broadly sub-truncate lobes beyond middle (Fig. 4C); dorsal internal gonopod IX (d.i.gon.IX) large, highly scletotized and with deep V-shaped apicomesal excision in dorsal view (Fig. 4B); internal gonopod VIII (i.gon.VIII) composed of broad semicircular lobe apicoventrally and small tongue shaped lobe apicodorsally (Fig. 4C).

Setodes charax Yang & Morse, n. sp. (Fig. 8) Diagnosis. This new species belongs to Setodes dhanavriddha Group (Schmid 1987), to which two additional species have been included: St. laertes Malicky & Chantaramongkol 2006 from Nepal and St. lailaps Malicky & Chantaramongkol 2006 from Thailand. The male genitalia of our new species have the form of those of St. antardhana Schmid 1987, St. gherni Schmid 1987, and St. divyarupa Schmid 1987 from India in the following characters: 1) The long lateral branches of segment X are positioned at 1/4 distance below the dorsal margin of segment IX, such that the dorsum of IX seems highly elevated in lateral view; 2) the lateral branches of X are serrate subapically and are usually fringed with long hair; and 3) the phallic parameres are very long and slender, arched parallel to the phallicata. However, the male genitalia of St. charax differ from those of these three species in the following characters: 1) The lateral branches of tergum X each is forked apically in lateral or dorsal views (not branched at the apex in St. antardhana and St. gherni, with the apex branched into three stout teeth in St. divyarupa); 2) the phallicata is slen- der, trough-shaped, and the dorsal ridges are not expanded laterally for reception of the parameres (the dorsal ridges are expanded for reception of the parameres in the above three species); 3) the parameres are very long and slender, each deeply divided at 1/4 length into two subparallel branches (the parameres are not divided in St. antardhana, St. gherni, and St. divyarupa). Adult. Length of each male forewing 6.0��� 6.5 mm (n = 2). Specimens in alcohol generally pale, forewings pale brown, covered with concolorous fine hair. Wing venation similar to Setodes scutatus n. sp. (Figs. 9F, 9H), except hind wing cell M1+2 short, such that cell R3 at least 1.5 times longer than cell M1+2 (Fig. 8F arrows), tips of fore- and hind wings acute. Male genitalia. Segment IX anterior margin concave and strongly reduced subdorsally at 4/5 height and posterior margin deeply indented at bases of lateral branches of segment X (Figs. 8A, 8B), in dorsal view with mesal 3/5 forming trapezoid plate (Fig. 8B), and with pair of setal warts near its anterior margin (Figs. 8A, 8B); broadly rectangular and nearly 2/3 as long as wide in ventral view (Fig. 8C). Preanal appendages apparently absent. Tergum X represented by pair of highly sclerotized lateral branches, each arising at 1/4 distance from dorsal margin of segment IX, fringed with long hair near midlength, and with forked apex (Figs. 8A, 8B); in dorsal view, branches slightly asymmetrical in respect to one another, stout at basal 1/2, each gradually narrowing to forked and subapically toothed apex (Fig. 8B). Inferior appendages short and set vertically, generally kidney shaped in lateral view; each with three branches positioned on dorsal half, two of them located on inner posterior margin of appendage, upper one finger-like with acute tip and lower one rod-like with truncate tip; longest, third branch arising between the other two in lateral view, slender, set on outer posterior margin near top; in addition, below these branches near middle of appendage, stout seta arising from long chaza on outer posterior margin, posterolateral margin below chalaza sinuous and with few setae (Fig. 8A). Phallobase plate-like, phallicata long, trough-like; arched about 90�� in middle, with basal 1/2 about 2 times as broad as distal 1/3, with pair of small, triangular phallotremal sclerites embedded subapically in endophallic membranes; pair of parameres slender, almost as long as phallicata, each deeply divided into two branches proximate to each other in basal 3/4, divergent slightly near apices (Figs. 8B, 8D).

Psilotreta longicornis sp. n. Yang & Morse (Fig. 11) Ol��h & Johanson (2010) established three species groups for this genus, they summarized diagnostic characters for the Psilotreta trimeresuri Species Group as follows: (1) harpagones originate mesally on coxopodites; (2) numerous small spines are present on the apex of the harpagones, and (3) there are 2 pairs of spines in the phallic apparatus. Our new species seems to have the typical diagnostic characters (1) and (2), however, there is only one pair of paramere spines in our new species, which is the main character for their Psilotreta japonica Species Group. Based on our study of Chinese species, character (1) (���harpagones originate mesally on coxopodites���) is actually caused by the well-developed ventral lobe along the ventral margin of the coxopodite (Fig. 11A), the shape and size of this ventral lobe varying in different species. So far, a total of 12 species have been found in southern China which possess some character combination of the above two species groups: Coxopodites having well-developed ventral lobes, dense small spines present on the apex of the harpagones, and the phallus having only one pair of paramere spines. Those species are the following: Psilotreta kwantungensis Ulmer 1926, Ps. lobopennis Hwang 1957, Ps. anfracta Yuan & Yang 2008, Ps. expers Yuan & Yang 2008, Ps. rectangular Yuan & Yang 2008, Ps. spinata Yuan & Yang 2008, Ps. tenuispina Yuan & Yang 2008, Ps. applanata Yuan & Yang 2010, Ps. dardanos Malicky 2000, Ps. grossa Yuan & Yang 2010, Psilotreta horrida Yuan & Yang 2010, Psilotreta yunnanensis Yuan & Yang 2010. Diagnosis. This new species is most similar to Psilotreta anfracta from southeastern China (Jiangxi), but differs from it by the following characters: (1) The dorsal process of abdominal segment X is broadly hood-like, with long horn-like lateral processes produced basoventrally (the dorsal process of X is slender and cylindrical, with lateral processes produced apicoventrally in Ps. anfracta); (2) the ventral processes of segment X are broadly crescentic, each with its sharp end directed anterad (they are sickle-shaped, each with a long ���handle��� and with its sharp end directed posterad in Ps. anfracta); (3) the inferior appendages are each with the ventral lobe of its coxopodite slightly produced in a short, blunt lobe (each is strongly produced ventroposterad in a triangular lobe, with its apex reaching the tip of the harpago in ventral view in Ps. anfracta). Adult. Length of each male forewing 14.0��� 14.5 mm (n = 2). Body light brown, antennae, palps and legs light yellowish brown; forewings pale yellowish brown. In forewing, R1 running separately to margin, Fork I rooted, with R2 segregating from mid-length of discoidal cell and with its apex close to tip of R1; stalk of fork II 1.5 times as long as crossvein r, cross vein r-m very short (Fig. 11F). Male. Anterior margins of segment IX produced forward into large rounded lobes, posteroventral margins strongly convex in lateral view (Fig. 11A); median dorsal process of segment IX indistinguishably fused with segment X, forming a long, broad hooded dorsal process of X (Fig. 11B), in dorsal view, this hood about 2 times as long as its basal width, evenly narrowing to truncate apex, with small triangular projection on each lateral margin near base (Fig. 11B arrow), and pair of long horn-like lateral processes produced from dorsal process of X basoventrally in lateral view (Figs. 11A). Ventral processes of X (= intermediate appendages?), forming pair of sclerotized, broad crescentic structures, each with its sharp end directed anterad and with short spine on each dorsal margin near middle, visible in both lateral and dorsal views (Figs. 11A. 11B). Preanal appendages long, lanceolate, each broadest at basal 2/3, tapering gradually to apex (Fig. 11A). Inferior appendages each with broad coxopodite, 1.5 times as long as wide in lateral view, each apicoventral lobe short and blunt (Figs. 11A arrow, 11C arrow). Harpagones each having broad base and narrow apex, nearly 2 times as long as its basal width in lateral view, but short and stout with tips broadly rounded in ventral aspect and each bearing numerous short, black teeth apically (Figs. 11A, 11C). Phallus generally tube-like, phallobase long, cylindrical, slightly decurved and enlarged apicoventrally; phallicata about 1/3 length of phallobase (Fig. 11D), with semi-membranous, apex round in lateral view (11D), bilobed in ventral view (11C); one pair of paramere spines, short and stout (Fig. 11C).

Ceraclea (Athripsodina) aerumnula sp. n. Yang & Morse (Figs. 2 A–2D) Diagnosis. This new species is somewhat similar to C. (A.) excisa (Morton 1904), C. (A.) shuotsuensis (Tsuda 1942), and C. (A.) globosa Yang & Morse 1988 from northeastern China (Yang & Morse 2000) in the following character of the male genitalia: Inferior appendages each with well-developed phallic guide, but it differs from those in having the phallic guide broadly trapezoidal in caudal view (triangular in C. excisa, C. shuotsuensis, and C. globosa). On the other hand, the new species is somewhat similar to C. (A.) emeiensis Yang & Tian 1987 from central China, and C. (A.) brachyacantha Yang & Tian 1987 from southeastern China in the following character: Tergum X is slender with its distal half highly elevated in lateral view. However, it differs from those in having the basoventral lobe of each inferior appendage bearing a long, stick like black rod apically (lacking from the basovental lobe in C. emeiensis, a very short apical spine in C. brachyacantha); and in the phallus has only one stout, rod-like paramere spine with the distal 1/3 twisted to the left, which is different from all of the five species above. Adult. Length of each male forewing 7.0– 7.5 mm (n = 5), of each female forewing 6.0 mm (n = 2). Most type specimens teneral, generally pale; only holotype non-teneral, fully mature. Head and thorax brownish-black, antennae light brown. Wings dark brown, covered with concolorous fine hair; with traces of few small white spots sparsely scattered on distal half of each forewing near anterior margin. Male genitalia. Segment IX basically rectangular, abruptly shorter longitudinally on dorsal 1/ 3 in lateral view (Fig. 2A), forming narrow transverse band projecting caudad in arch in dorsal view. Preanal appendages short, oval in lateral view (Fig. 2A); fused with each other in basal half, each obtuse apically in dorsal view (Fig. 2B). Tergum X about 2 times as long as preanal appendages, broadly triangular at basal half with distal half abruptly narrowing to blunt apex in dorsal view (Fig. 2B); narrow, with basal 2/3 elevated obliquely then smoothly curved downward and backward in lateral view (Fig. 2A); lateral processes of tergum X stout, originating basally, about 2/3 as long as tergum, divergent from tergum X apically, apex of each bearing short, upturned, spine-like process (Figs. 2A, 2B). Basoventral lobe of each inferior appendage broad basally, about as long as main body of appendage including apicodorsal lobe, with single, stick-like sclerotized rod apically, nearly 1/2 as long as basoventral lobe (Fig.); main body of inferior appendage about 1.5 times as long as thick, subapicodorsal lobe as long as main body of appendage in lateral view (Fig. 2A), mesal ridge represented as small setose lobe, phallic guide produced in large plate in caudal view (Fig. 2C); harpago 1/2 as long as subapicodorsal lobe, with triangular apex directed mesad in caudal view (Fig. 2C). Phallobase with anterior portion nearly 3 times as broad as posterior apicoventral lobes and about 1/2 as long; one stout paramere about 3/4 as long as phallobase with distal 1/4 curving to left (Fig. 2C).

Setodes scutatus n. sp. Yang & Morse (Fig. 9) Diagnosis. This species belongs to the Setodes argentiferus Group (Schmid, 1987), and is most similar to Setodes trilobatus Yang & Morse 1989 from northern China (Shaan-xi) in the following characters: 1) abdominal tergum X is broad, roof-like, its apicomesal portion is distinctively protruded backward beyond two apicolateral ends; 2) each inferior appendage is tri-branched; 3) the phallicata of the phallus is dilated subapically with a beak-like tip. It can be differentiated easily from S. trilobatus in the following characters: 1) the lower branch of each inferior appendage is long, blade like, with its length 1.2 times the length of the ventral margin of segment IX, and with a triangular projection on its dorsal margin in lateral view (the lower branch of each inferior appendage is a short oval lobe, with its length 2/3 the length of the ventral margin of segment IX in S. trilobatus); 2) the parameres are each branched subapically into two decurved hooks (not branched subapically in S. trilobatus); 3) the mesal branch of each inferior appendage is stout, with its apex strongly produced mesad into a triangular process and with the mesal end acute in caudal view, (the mesal branch is a narrow band, its apex with the mesal process slender in caudal view in S. trilobatus); 4) the paired basomedian lobes of tergum X are about as broad as the preanal appendages and with truncate apices in dorsal view (much smaller and subtriangular in S. trilobatus); and 5) the phallus has a narrow crescent phallobase (the phallobase is semicircular in S. trilobatus). Adult. Length of each male forewing 6.5–7.0 mm (n = 5). Specimen in alcohol generally pale yellow, forewings without evidence of golden spots or striae, covered with concolorous fine hair. Wing venation typical for genus, cell R3 (between veins R3 and R 4+5) almost as long as fork of MA and MP (between veins M1+2 and M3+4), tips of fore- and hind wings acute (Figs. 9F, 9H). Male genitalia. Segment IX longitudinally short dorsally, forming narrow transverse band (Fig. 9A). Preanal appendages large, setose mounds, positioned beside basomedian lobes of tergum X in dorsal view (Fig. 9B). Tergum X long and broad, roof-like with prominent median ridge (Fig. 9A); in dorsal view 1.5 times as long as wide, basal median lobes each with truncate apex and about as broad as preanal appendage (Fig. 9B), apicomesal end distinctively protruding backward beyond two apicolateral ends, forming trilobed apex (Fig. 9B). Inferior appendages each trifurcate, lower branch of appendage elongate blade-like, 1.2 times as long as ventral margin of segment IX and with triangular projection on midlength of dorsal margin in lateral view (Fig. 9A lower arrow); mesal branch short, 1/2 as long as upper branch of inferior appendage, with apex blunt in lateral view but in caudal or dorsal views strongly produced mesad into triangular process with acute mesal end (Figs. 9A middle arrow, 9A-a); small, setose papilla visible at base in caudal view (Fig. 9 C-a arrow); upper branch slender and sinuate, 2/3 as long as lower branch of inferior appendage, with apex bearing two long setae (Figs. 9A upper arrow, 9C-a.). Phallus with narrow crescentic phallobase; pair of parameres stout, originating above phallobase, curved caudad then sloping caudoventrad, each branched subapically into two decurved hooks with inner hook nearly transparent; phallicata strongly arched, slender, parallel sided in basal half in lateral view, with distal half expanded dorsolaterally into two broad subapical lobes, with abruptly narrowed beak-like apex directed downward (Fig. 9D).

Phraepsyche acuminata, n. sp. Yang & Morse (Fig. 10) So far Phraepsyche consists of only 4 species from Southeast Asia, Phraepsyche danaos Malicky & Sompong 2000 (in Malicky et al. 2000) from Thailand, Ph. epha Malicky 2008 and Ph. pectinata Oláh & Johanson 2010 from Vietnam, and Ph. yitungshana Oláh & Johanson 2010 from Hong Kong, China. The diagnostic characters for this genus have been given by Oláh & Johanson 2010. Diagnosis. This species is most similar to Ph. epha from Vietnam in the wing venation, the distribution of the hair belt on the forewings, the wing fold pattern of the hind wings, and the similar general shape of male genitalia. The new species is distinguished from Ph. epha in the following characters: 1) the longitudinal hair belt on each forewing extends from the wing base (base of Cu), crosses over the anastomosis, then bends upward between R5 and the MA area to a blunt wing tip (in Ph. epha the longitudinal hair belt on each forewing is distributed only from the anastomosis to an acute wing tip); 2) the anal margins of the hind wings are sinuate and bear long marginal hairs and a row of dark, robust setae directed upward (in Ph. epha, anal margins of hind wings are not sinuate and without the additional row of dark, robust setae); 3) inferior appendages of the male genitalia have harpagones that are slender and smooth, goat-horn-like, each with its distal 1/3 sharpened to an acute apex and turned downward and mesad, (in Ph. epha, harpagones are thick and bearing many tiny setae, each evenly tapered and straight to blunt apex); and 4) the phallicata is about 2/5 as long as the phallobase and separated from it by a dorsal indentation and a ventral constriction in lateral view (dorsal and ventral margins parallel in Ph. epha). Adult. Length of each male forewing 6.2–8.2 mm (n = 3). Specimens in alcohol for more than 10 years generally yellowish brown. Head, maxillary palps each 5-segmented, first to third segments fringed with short setae, fourth and fifth segments almost bare and equal in length (10E). Scape of each antenna almost as long as head, with anterior surface concave, densely filled with hairs (Fig. 10I); pectination on flagellum from first to twelfth segments, first pectinal branch very short, only 1/2 as long as any others, all other branches subequally long. Wings translucent yellowish brown, venation of fore- and hind wings somewhat similar to that of Ph. epha, with Forks I, II, and V in forewings and Fork V in hind wings, but longitudinal hair belt on each forewing from wing base to wing tip distinctive, densely bearing fine hairs and scale hairs from base of Cu to anastomosis, then bending upward between R5 and MA area to blunt wing tip, membrane of belt area concave below wing surface and with paler color than rest of wing (Fig. 10F). Hair belt on each hind wing between stems of R and M in basal half then at anatamosis crossing membrane at base of cell R5 to fill cell R3 between apparent R2+3 and R4+5; in addition two wing folds located anterior of stem of M and anterior of basal half of Cu2; anal margin sinuate, fringed with ordinary marginal hairs and distinctive row of dark robust setae directed upward (Fig. 10H). Long, digitate projection arising from posterior margin of abdominal sternum VI, densely covered with short, fine setae, with its apex reaching posterior margin of sternum VII (Fig. 10G). Male genitalia. In lateral view (Fig. 10A), greatest longitudinal length of segment IX 1/3 height, its anterior margins protruding forward in 80° angle at 1/4 distance from ventral margin. Distal half of tergum X, in dorsal view, forming pair of triangular lobes, each with 4–5 stout setae on outer margin and with its medial margins parallel to each other; in addition, setose medial hump present mesally at bases of triangular lobes (Fig. 10B) prominent in lateral view (Figs. 10A, 10 B-a). Preanal appendages as long as segment IX with rounded apices in lateral view. Inferior appendages with coxopodite stout, erect, with distal half slightly curved backward (Fig. 10A), length between base of appendage and subapical lobe about 3 times its width in ventral view and subapicodorsal lobe curving mesad, about half as broad as mean width of coxopodite (Fig. 10C). Harpagones long, goat-horn-like, stout in basal 1/4 with distal 1/3 sharp and turned downward and mesad (Figs. 10 A–10C), each arising from distal 1/3 of appendage in ventral view (Fig. 10C). Phallus about as long as inferior appendages, tubular phallobase nearly straight, phallicata appearing as continuation of sclerotized phallobase, about 2/5 length of phallobase and separated from it by dorsal indentation and ventral constriction, then narrowing to blunt triangular apex in lateral view (Fig. 10D); in ventral view, phallicata widely opened with endotheca visible (Fig. 10 Da); ejaculatory duct with conspicuous twist at 1/2 length of phallus; phallotremal sclerite appearing as circular ring in lateral and ventral views (Figs. 10D, 10 D-a).

Stactobiella mutica n. sp. (Fig. 4) Diagnosis. The male of the new species is somewhat similar to that of Stactobiella alasignata BOTOSANEANU 1993 (Far East Russia) in having a deep posterior concavity on dorsum IX, a subgenital plate with a long stem, and inferior appendages bearing long setae. But S. mutica n. sp. differs from S. alasignata in having 1) the posteroventral corners of pleura IX forming slender projections with acute tips (S. alasignata is without projections on the posteroventral corners of pleura IX); 2) inferior appendages positioned underneath segment IX (in S. alasignata they are positioned posterior to segment IX); and 3) the long setae occur only on the anterior portions of the inferior appendages and the posterior portions of the appendages are thumb-like, each with a truncate apex bearing one setae (in S. alasignata the long setae are set all along the posterior margins of the inferior appendages and the posterior 1 / 3 portion of each inferior appendage is elongated with a rounded apex bearing at least 3 setae). Male. Length of each forewing 1.8���1.9 mm (n= 8). Antennae each 18 -segmented (n= 8). Ventral process on sternum VII small, short, triangular in lateral view (Fig. 4 E). Male genitalia.

Agraylea CURTIS Agraylea CURTIS 1834, 217; type species: Agraylea sexmaculata CURTIS 1834 (selected by WESTWOOD 1840, 51). The genus Agraylea contains only 9 extant species, of which 3 species are West Palearctic, 2 Nearctic, 1 East Palearctic, 2 East–West Palearctic, and 1 Nearctic–West Palearctic (MORSE 2015). According to MARSHALL (1979), male genitalia of Agraylea generally have a long ventral process on segment VII; segment IX usually has a deep dorso-anal indentation; tergite X is reduced to a short membranous lobe; the inferior appendages are well developed with posterior ends never concave; the subgenital plate tapers posteriorly without any lateral projections but with a median ventral projection in ventral view; and the aedeagus is relatively short and stout with distinct proximal and distal halves and spiral titillator (diagnosis modified from MARSHALL 1979).

Microptila hamatilis n. sp. (Fig. 3) Diagnosis. The new species is somewhat similar to Microptila hintama OLÁH 1989 from Vietnam in having a broad subgenital plate with lateral margins curling up in dorsal view.

Microptila RIS Microptila RIS 1897, 416; type species: Microptila minutissima RIS 1897 (monobasic). The genus Microptila contains 16 extant species, of which 13 species are Oriental, 1 species is West Palearctic, 1 species is Afrotropical, and 1 species is Afrotropical���West Palearctic (MORSE 2015). The new Microptila species described below is the first representative of the genus known in the typical Oriental Region of China (Yun-nan Province). Microptila species have forewings that are each ~ 1.5 ���3.0 mm long, 3 ocelli, a mesoscutellum that is asymmetrically rhomboidal with its anterior margin widely convex in an obtuse angle and larger than its posterior angle, a metascutellum that is trapezoidal, and a spur formula of 0-3 - 4. Microptila male genitalia have segment IX with a shallow excision along the dorsoposterior margin; tergum X forms a short membranous dorsal lobe; inferior appendages are elongate, although not so long as in Ugandatrichia and arising from the ventroposterior margin of segment IX with apices slightly incurved; the subgenital plate is elongate; and the aedeagus is long with a short spiral titillator (diagnosis modified from MARSHALL 1979)., Published as part of Zhou, Lei, Yang, Lian-Fang & Morse, John C., 2016, New species of microcaddisflies from China (Trichoptera: Hydroptilidae), pp. 203-219 in Zootaxa 4097 (2) on page 208, DOI: 10.11646/zootaxa.4097.2.3, http://zenodo.org/record/265546

Pseudoxyethira thingana (OL��H) (Fig. 7) Scelotrichia thingana OL��H 1989, 267, fig. 12; type locality: Vietnam. Remarks. This species is recorded from China for the first time. The male genitalia of our single specimen from southern China is basically congruent with the original description and drawings of S. thingana. However, the inferior appendages of our specimen are somewhat similar to the drawing of O. nana (MEY 1996) when viewed ventrally (Fig. 7 C), but like O. thingana, our specimen can be distinguished from P. nana by the fact that 1) the ventral process on segment VII is absent (present in P. nana), 2) the anterior apodemal rods of segment IX are set dorsally, they are no more than 3 times as long as segment IX in lateral view, and each rod is not straight and needle-like (Fig. 7 A) (the anterior apodemal rods of segment IX are set ventrally, they at least 4 times as long as segment IX in lateral view, and each rod is straight and needle-like in P. nana); and 3) the basal 1 / 5 of the fused inferior appendages are convex laterally and gradually narrowing to the base in ventral view (Fig. 7 C) (they are slightly concave, abruptly narrowing to a handle in the basal 1 / 4 in P. nana). The male genitalia of our specimen are redrawn here for comparison. Taxonomic problems resulting from adherence with the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999) certainly are to be corrected in compliance with professional standards and journal requirements (as for Zootaxa). Recently, though, some so-called ���cyber nomenclaturalists��� (O���HARA 2011) have undertaken searches for junior homonyms among genera of animals. Upon finding a junior homonym, they then have published a replacement name, generally in an isolated paper, without communicating with specialists for the affected taxon, without peer review, and in obscure journals that they edit and publish themselves. The practice has been decried in Zootaxa by O���HARA (2011) and, with respect to old junior homonyms, by NEM��SIO (2011). As they noted, lack of expertise with the affected taxa by these nomenclaturalists can often lead to errors and complications that must later be corrected (O���HARA 2011). Such is the case also with the junior homonym Scelotrichia ULMER 1951, homonym of Scelotrichia REUTER 1890 (Hemiptera: Nabidae, a subgenus of Prostemma). Upon discovery of this overlooked homonymy, KO��AK & KEMAL (2012) published for this hydroptilid genus the replacement name Orientalitrichia nomen novum in their Centre���s Miscellaneous Papers, apparently without peer review and without consulting modern trichopterologists. [Dr. Georg ULMER (1877���1963) is dead and could not be consulted.] Had their proposal been peer reviewed, especially by a modern trichopterologist, they would have learned that ULMER���s name has at least one available synonym and should have been replaced by the oldest of these, Pseudoxyethira SCHMID 1958, rather than a new name (ICZN 1999, Article 60.2).

Allotrichia rhynchophyllum n. sp. (Fig. 2) Diagnosis. The new species is somewhat similar to Allotrichia pallicornis, the type species of this genus, in the general shape of male genitalia: 1) The anterior margin of segment IX has deep dorsal and ventral indentations forming an anterolateral lobe with a 70���75 �� angle on each side in lateral view; the posterodorsal margin is nearly straight. 2) The subgenital plate bears a pair of slender, dorsolateral projections. The new species differs from A. pallicornis in having 1) segment X rectangular, 2 times as broad as long in dorsal view; 2) the distal half of the subgenital plate strongly downcurved and with an acute apex in lateral view; and 3) inferior appendages with posterior margins slightly concave; whereas segment X is square, the subgenital plate is directed horizontally backward and with a blunt apex, and the inferior appendages have their posterior margins deeply concave in A. pallicornis. Male. Length of each forewing 3.5 mm (n= 1), antennae each 25 -segmented. Ventral process on sternum VII long, with rough ventral surface in lateral view, subapically slightly concave, and with distal end enlarged in ventral view (Fig. 2 E). Male genitalia. Dorsum of segment IX completely divided, with transverse posterior margins nearly straight and aligned in dorsal view; pleura IX about 2 / 3 as long as high in lateral view, anterolateral margins protruding anterad in broadly rounded lobe forming a 70���75 �� angle on each side, upper posterolateral portion of pleura IX slightly concave and lower posterolateral portion protruding slightly backward forming blunt lobe with about 120 �� angle on each side (Fig. 2 A). Tergum X rectangular, 1 / 2 as long as wide in dorsal view. Inferior appendages quadrangular, each with dorsal margin 2 / 3 as long as its ventral margin, and with posterior margin of appendage shallowly concave in lateral view (Fig. 2 A); in ventral view, exposed portion of appendage almost quadrate, with posteior margin slightly concave (Fig. 2 C); inner suface of appendage with many tiny, acute protuberances evenly spaced (Fig. 2 B, larger arrow). Subgenital plate well developed with basal half extending laterally downward and forming rectangular lateral lobe on each side of plate (Fig. 2 A, 2 B), distal portion tongue-like in dorsal view, strongly downcurved with acute tip in lateral view (Fig. 2 A); pair of slender, dorsolateral projections set on each side of mid distance of plate, small acute process visible in both dorsal and lateral views just below base of each slender lateral projection (Fig. 2 A, 2 B, smaller arrow in each). Aedeagus relatively short and stout with proximal half 1.5 times as long as distal half, spiral titillator circling segment 1.5 times with the apical portion directed straight backward, apex of aedeagus slightly enlarged and bilobed (Fig. 2 D).

Agraylea CURTIS Agraylea CURTIS 1834, 217; type species: Agraylea sexmaculata CURTIS 1834 (selected by WESTWOOD 1840, 51). The genus Agraylea contains only 9 extant species, of which 3 species are West Palearctic, 2 Nearctic, 1 East Palearctic, 2 East���West Palearctic, and 1 Nearctic���West Palearctic (MORSE 2015). According to MARSHALL (1979), male genitalia of Agraylea generally have a long ventral process on segment VII; segment IX usually has a deep dorso-anal indentation; tergite X is reduced to a short membranous lobe; the inferior appendages are well developed with posterior ends never concave; the subgenital plate tapers posteriorly without any lateral projections but with a median ventral projection in ventral view; and the aedeagus is relatively short and stout with distinct proximal and distal halves and spiral titillator (diagnosis modified from MARSHALL 1979)., Published as part of Zhou, Lei, Yang, Lian-Fang & Morse, John C., 2016, New species of microcaddisflies from China (Trichoptera: Hydroptilidae), pp. 203-219 in Zootaxa 4097 (2) on page 204, DOI: 10.11646/zootaxa.4097.2.3, http://zenodo.org/record/265546, {"references":["Agraylea CURTIS 1834, 217; type species: Agraylea sexmaculata CURTIS 1834 (selected by WESTWOOD 1840, 51).","Westwood, J.

Stactobiella parallelica n. sp. (Fig. 5) Diagnosis. This new species from southeastern China is very similar to S. mutica n. sp., distributed in southwestern China, but S. parallelica n. sp. is readily distinguishable from S. mutica in that 1) the posteroventral hooks of pleura IX are very short, with tips tilted upward in lateral view and set far apart in ventral view (in S. mutica the hooks are slightly longer and straighter, with tips pointed backward in lateral view and very close to each other in ventral view); 2) the posterior 1 / 2 of the inferior appendages are straight, rod-like, and parallel to each other, each having a narrow apex in ventral view (in S. mutica the posterior portion of each inferior appendage is thumb-like, only 1 / 3 of the length of the appendage, with its apex obliquely truncate); and 3) the subgenital plate is less than 1 / 2 as long as the inferior appendages in ventral view (in S. mutica the plate is about 2 / 3 as long as the inferior appendages). Male. Length of each forewing 1.5���1.7 mm (n= 25). Antennae each 18 -segmented (n= 25). Ventral process on sternum VII small, short, triangular in lateral view. Male genitalia. Anterior apodemes of segment IX projecting from middle of segment IX and extending forward to or slightly surpassing anterior margin of segment VII, posteroventral corners of pleura IX forming short hooks with acute tips tilted upward in lateral view (Fig. 5 A), and strongly curved mesad with their tips set far apart in ventral view (Fig. 5 C); posterior dorsum of segment IX forming subrectangular concavity (Fig. 5 B). Tergum X membranous, subrectangular, with anterior margin about 1.3 times as broad as posterior margin and shallow emargination presented on posterior margin in dorsal view (Fig. 5 A); in lateral view, apical portion of X broadly rounded, slightly exposed beyond posterior margins of segment IX. Inferior appendages partly exposed from beneath segment IX with their posterior ends extending beyond the hooked tips of segment IX in lateral view (Fig. 5 A); in ventral view, anteroventral 1 / 2 of inferior appendages thick and straight-edged laterally, semicircular mesally, together outlining open oval, each with row of setae on inner surface of anterior end and with single pair of short setae submesally, posterior 1 / 2 of inferior appendages straight, rod-like, parallel to each other, with narrow apices pointed backward and each bearing two setae, one near base of rod and one at tip (Fig. 5 C).

Stactobiella mutica n. sp. (Fig. 4) Diagnosis. The male of the new species is somewhat similar to that of Stactobiella alasignata BOTOSANEANU 1993 (Far East Russia) in having a deep posterior concavity on dorsum IX, a subgenital plate with a long stem, and inferior appendages bearing long setae. But S. mutica n. sp. differs from S. alasignata in having 1) the posteroventral corners of pleura IX forming slender projections with acute tips (S. alasignata is without projections on the posteroventral corners of pleura IX); 2) inferior appendages positioned underneath segment IX (in S. alasignata they are positioned posterior to segment IX); and 3) the long setae occur only on the anterior portions of the inferior appendages and the posterior portions of the appendages are thumb-like, each with a truncate apex bearing one setae (in S. alasignata the long setae are set all along the posterior margins of the inferior appendages and the posterior 1 / 3 portion of each inferior appendage is elongated with a rounded apex bearing at least 3 setae). Male. Length of each forewing 1.8–1.9 mm (n= 8). Antennae each 18 -segmented (n= 8). Ventral process on sternum VII small, short, triangular in lateral view (Fig. 4 E). Male genitalia. Anterolateral apodemes of segment IX set on dorsal half, extending to middle of segment VII; posteroventral corners of pleura IX forming slender hooks with acute tips tilted upward in lateral view (Fig. 4 A) and strongly curved mesad with tips almost meeting each other in ventral view (Fig. 4 C); posterior dorsum of segment IX forming deep trapezoidal concavity (Fig. 4 B). Tergum X membranous, trapezoidal with anterior margin about 3 times as broad as posterior margin and with shallow emargination on posterior margin in dorsal view (Fig. 4 B); in lateral view, apical portion of segment X forming triangular lobe with blunt apex extending beyond segment IX. Inferior appendages partly exposed from beneath segment IX with their posterior ends not extending beyond hooked tips of segment IX in lateral view (Fig. 4 A); in ventral view, anteroventral 2 / 3 of inferior appendages thick and semicircular, together outlining open oval with many long setae on inner surfaces of anterior ends and with single pair of short setae submesally; posterior 1 / 3 of each inferior appendage thumb-like, with apex obliquely truncated and bearing one setae on apicomesal corner. Subgenital plate only about 2 / 3 as long as inferior appendages in ventral view, anteriorly forming long stem covered with tiny setae, posterior half fan-like, with apical region 8 times as broad as stem in ventral view (Fig. 4 C). Aedeagus long, simple tube, broadest in basal 1 / 4, slightly thicker in third 1 / 4, apical portion slightly curved (Fig. 4 D). Holotype.

Allotrichia MCLACHLAN Allotrichia MCLACHLAN 1880, 505, 508; type species: Agraylea pallicornis EATON 1873 (monobasic). The genus Allotrichia only contains 8 extant species and 3 fossil species, all of which have a West Palearctic distribution (MORSE 2015). Our new species of Allotrichia from northeastern China represents a remarkable extension of the range of Allotrichia to include now both the West Palearctic Region and the East Palearctic Region. Generally they are very similar to those of Agraylea except 1) the inferior appendages are short and broad with concave posterior margins and 2) the subgenital plate bears a pair of characteristic asymmetrical dorsolateral projections. We agree that the presence or absence of fork 1 (fork of R 2 and R 3) in hind wings has not proven to be a consistent feature in either Agraylea or Allotrichia (MARSHALL 1979); hind wing fork 1 is absent in all the new Chinese species in these two genera (e.g., Fig. 1 E)., Published as part of Zhou, Lei, Yang, Lian-Fang & Morse, John C., 2016, New species of microcaddisflies from China (Trichoptera: Hydroptilidae), pp. 203-219 in Zootaxa 4097 (2) on page 206, DOI: 10.11646/zootaxa.4097.2.3, http://zenodo.org/record/265546

Stactobiella MARTYNOV Stactobiella MARTYNOV 1924, 37, 57; type species: Stactobia ulmeri SILTALA 1908 (monobasic) [a synonym of Microptila risi FELBER 1908, 14– 16, synonymized by SPURIS 1989, 12] The genus Stactobiella currently consists of 13 described species occurring in the East Palaearctic (4 species), the Western Palaearctic (2 species), the Nearctic (5 species), and the Oriental (2 species) Regions (MORSE 2015). XUE & YANG 1990 described Stactobiella pulmonaria from China (Hainan island), but MALICKY & CHANTARAMONGKOL (2007) transferred the species to Chrysotrichia, based on his specimens from Thailand and Laos, and he synonymized Chrysotrichia tanduk WELLS & HUISMAN 1993 (Malaysia) with this species. We reexamined the type specimens of S. pulmonaria and agree with the opinion of WELLS & HUISMAN (1993), the typical 1-3 - 4 tibial spur formula suggested that our species should be placed in Stactobiella, but the male genitalia are typical of Chrysotrichia. Therefore, the species Chrysotrichia pulmonaria (XUE & YANG 1990) became the first species of that genus known in China. In this study, two new species, Stactobiella mutica n. sp. and Stactobiella parallelica n. sp., have been found in Oriental China and Stactobiella biramosa from northern China (Hei-long-jiang) is new to the Chinese fauna. Stactobiella species have forewings that are ~ 1.5 –3.0 mm; 3 ocelli; the metascutellum is long, as wide as or slightly narrower than the metascutum; the spur formula is 1-3 - 4. Stactobiella male genitalia have segment IX well developed with long anterior apodemes, tergum X is membranous, the shape of the inferior appendage varies among species, the subgenital is plate strongly sclerotized, arched; the aedeagus is a single tubule in most species (diagnosis modified from MARSHALL 1979).

Agraylea dactylina n. sp. (Fig. 1) Diagnosis. The new species differs from those species whose distribution extends into the East Palearctic Region, such as A. sexmaculata, A. multipunctata CURTIS 1834, A. cognatella MCLACHLAN 1880, and A. taymyrensis MEY 2003, in having 1) inferior appendages that are stoutly triangular, with a broad base about 1 / 2 the height of segment IX in lateral view, with inner margins of each appendage concave and bearing a tiny tooth on the inner surface subapically in ventral view; 2) the basodorsal projections of the inferior appendages are absent; 3) the divided halves of dorsum IX each has its dorso-posterior end produced into a bilobed projection. However, in those 4 other species, the inferior appendages are elongate, each with its height only about 1 / 4 - 1 / 5 the height of segment IX in lateral view, the baso-dorsal projections of the inferior appendages are well developed; the inner margins of each inferior appendage is straight without any subapical teeth on the inner margin in ventral view, and the dorsoposterior ends of the divided tergum IX are not each produced into a bilobed projection. In addition, this new species is similar to A. multipunctata in the identical shape of the aedeagus and in the long subgenital plate, but differs from that species in that the inferior appendages are not divided, but each appendage is roundly incurved with a blunt tip in ventral view (each inferior appendage is divided into three lobes with the ventral lobe straight, acute at apex in ventral view in A. multipunctata). It differs from A. sexmaculata in having the tip of the subgenital plate extending as far as the apices of the inferior appendages and the spiral titillator circling the aedeagus 1.5 times with the distal half directed straight backward (the subgenital plate extends only to the mid length of the inferior appendages and the spiral titillator circles the aedeagus not quite 1.2 times in A. sexmaculata). Male. Length of each forewing 4.2 mm (n= 2), antennae 36 -segmented. Ventral process on sternum VII long, with enlarged apex having tiny denticles (Fig. 1 F). Male genitalia. Dorsum of IX completely divided, each half with dorso-posterior end produced into bilobed projection (bilob.d.pr.), with upper lobe bearing very tiny setae and with lower lobe slightly smaller in size and bearing long setae (Figs. 1 A, 1 B); pleura IX about as long as high in lateral view, anterior margins straight, posterior margins each with deep posterodorsal and posteroventral indentations, forming broadly rounded posterolateral lobe on each side (Fig. 1 A). Tergum X reduced to short membranous lobe, nearly quadrate in dorsal view; triangular in lateral view, broad at base with dorsal margin sloping caudoventrad (Fig. 1 A). Inferior appendages massively triangular in lateral view, with broad base about 1 / 2 height of segment IX; in ventral view, each inferior appendage about 3.5 times as long as basal width, with inner surface concave, distal half curved mesad and gradually reduced to blunt tip and bearing tiny tooth subapically (Fig. 1 B, 1 C). Profile of exposed portion of subgenital plate peach-shaped with single pair of setae on apicolateral edges, far from apicomedian projection in dorsal view (Fig. 1 B); full length of plate 3 times of its broadest width, with distal 1 / 3 tapering posteriorly to median ventral projection in ventral view (Fig. 1 C); in lateral view, distal half curved downward and narrowing to truncate tip extending nearly to apices of inferior appendages (Fig. 1 A). Aedeagus relatively short and stout with proximal and distal halves equal in length, spiral titillator circling aedeagus 1.5 times and with distal portion directed almost straight backward, apex of aedeagus slightly enlarged and bilobed (Fig. 1 D).

Discovery of this new Agraylea species from China is significant biogeographically as it extends the genus Agraylea distribution from Holarctic and Nearctic Regions to the Oriental Region at a latitude of N 30.0665 ��. However, the type specimens of our new species were collected from an unnamed waterfall, a tributary of the Da-du River with its headwaters originating in the Ya-la Snow Mountains���This tributary passes through the Zhe-duo Snow Mountain, with an altitude of 1675 m a.s.l. about 30 km away from the collecting locality, such that the water temperature of this stream was relatively low. Perhaps we can classify this area as belonging to the Oriental���Palearctic Boundary Region., Published as part of Zhou, Lei, Yang, Lian-Fang & Morse, John C., 2016, New species of microcaddisflies from China (Trichoptera: Hydroptilidae), pp. 203-219 in Zootaxa 4097 (2) on pages 204-206, DOI: 10.11646/zootaxa.4097.2.3, http://zenodo.org/record/265546, {"references":["Mey, W.

Microptila RIS Microptila RIS 1897, 416; type species: Microptila minutissima RIS 1897 (monobasic). The genus Microptila contains 16 extant species, of which 13 species are Oriental, 1 species is West Palearctic, 1 species is Afrotropical, and 1 species is Afrotropical–West Palearctic (MORSE 2015). The new Microptila species described below is the first representative of the genus known in the typical Oriental Region of China (Yun-nan Province). Microptila species have forewings that are each ~ 1.5 –3.0 mm long, 3 ocelli, a mesoscutellum that is asymmetrically rhomboidal with its anterior margin widely convex in an obtuse angle and larger than its posterior angle, a metascutellum that is trapezoidal, and a spur formula of 0-3 - 4. Microptila male genitalia have segment IX with a shallow excision along the dorsoposterior margin; tergum X forms a short membranous dorsal lobe; inferior appendages are elongate, although not so long as in Ugandatrichia and arising from the ventroposterior margin of segment IX with apices slightly incurved; the subgenital plate is elongate; and the aedeagus is long with a short spiral titillator (diagnosis modified from MARSHALL 1979).

Stactobiella biramosa MARTYNOV (Fig. 6) Stactobiella biramosa MARTYNOV 1929, 297, figs. 5���6. Remarks. This species is recorded from China for the first time. The male genitalia of our specimen from northern China are quite congruent with the drawings of Stactobiella biramosa provided by AREFINA et al. (2002), apart from the fact that 1) the pair of darkened bars within tergum X are not obvious (clearly observed in the specimens illustrated by AREFINA et al.), 2) the median spine on the lateral margin of each inferior appendage is absent (present on inferior appendages of the specimens of AREFINA et al.).

Nyctiophylax (Paranyctiophylax) crinalis n. sp. (Fig. 1) Diagnosis. This new species is very similar to N. suthepensis Malicky & Chantaramongkol 1993 from Thailand. It differs in that Nyctiophylax (Paranyctiophylax) crinalis n. sp. has the inferior appendages with their inner margins each bearing a row of long strong setae in ventral view, its basomesal setose lobe is semicircular in both lateral and ventral views and in ventral view this lobe is strongly sclerotized and broader than its main body. On the other hand, N. suthepensis has the inner margin of each inferior appendage without a row of long strong setae and the basomesal setose lobe is oval in ventral view and narrower than its main body. Another difference between the two species is that the phallus of the new species has a pair of long, needle-like parameres, at least as long as the phallus, and the phallicata is without any short spines, while N. suthepensis has thick parameres only half as long as the phallus and the phallicata has some additional short spines. Male. Length of each forewing 4.2–4.8 mm (N=16). Head light brown with dark yellowish antennae, pronotum light brown, meso- and metanota brown with warts light brown, forewings brown. Male genitalia. Sternum IX in lateral view nearly quadrangular, posterior margin protruding at middle and forming 135° angle (Fig. 1A); in ventral view anterior margin excised in U-shape with depth of 1/3 length of sternum, posterior margin with broad and very shallow concavity (Fig. 1C); dorsal region of tergum IX membranous, trapezoidal (Fig. 1B). Preanal appendages broad at base in lateral view, each approximately 2 times its middle width, apex obliquely truncate; basal half of mesoventral process broad, distal half acute and horn-like, directed downward. Tergum X long and tongue-like in lateral view; transparent, semi-sclerotized, with V-shaped incision apicomesally in dorsal view (Fig. 1B). Inferior appendages each about 7 times as long as its mid width in lateral view, slightly clavate, narrowed at middle, with basomesal setose lobe semicircular in lateral view (Fig. 1A); in ventral view each inferior appendage nearly parallel-sided, with inner margin bearing row of long thick setae, basomesal setose lobe strongly sclerotized, semicircular, broader than main body, with rounded apex (Fig. 1C).

Nyctiophylax (Paranyctiophylax) macrorrhinus n. sp. (Fig. 4) Diagnosis. This new species is very similar to N. zadok Malicky & Chantaramongkol 1993 from Thailand. It differs in that 1) the apical 1/3 of each inferior appendage is acute, horn-like and curved mesad in ventral view; 2) the preanal appendages are shorter than tergum X and the mesoventral process of each preanal appendage is slender and arched in a semicircle in lateral view, with a dorsoventrally depressed apex (Figs. 4A, 4D); and 3) the pair of phallic sclerites are slender, generally straight and only slightly sclerotized. In N. zadok, 1) each inferior appendage is straight, with a blunt apex; 2) the preanal appendages are much larger and longer than tergum X, each having its mesoventral process triangular with an apex acute in lateral view; and 3) the phallic sclerites are stout, horn-like, and strongly sclerotized. Male. Length of forewing 4.0– 5.4 mm (N = 10). Head brown with yellowish antennae, pronotum light brown, meso- and metanota brown, fore wings light brown. Male genitalia. Segment IX in lateral view with triangular protrusion anteriorly in ventral half but with round production posteriorly (Fig. 4A); in ventral view both anterior and posterior margins each with deep concavities such that midline of venter IX only 1/2 as long as segment (Fig. 4C); dorsal region of segment IX nearly membranous, sub-quadrate in dorsal view. Preanal appendages in lateral view (Fig. 4A) each broad at base with rounded apex not passing beyond apex of tergum X; mesoventral processes slender and arched in semicircle; in ventral view (Fig. 4D) much broader basally, nearly meeting on midline to support phallus, but not fused with each other, depressed apically. Tergum X in lateral view with each half divided into two lobes: upper lobe setose and apically beak-like, lower lobe smooth with blunt apex bearing 2 setae (Fig. 4A); in dorsal view (Fig. 4B) transparent, semi-sclerotized, with deep U-shaped incision apicomesally. Inferior appendages broad in lateral view (Fig. 4A), each broad at base, gradually narrowing to acute apex; in ventral view (Fig. 4C) apical 1/3 curved mesad with acute horn-like apex and with thin, translucent, triangular mesal edge. Phallus tube-like, with pair of long, stout and straight paramere spines; phallic sclerites slender, narrow both anteriorly and posteriorly, generally straight and lightly sclerotized; lacking other spines (Fig. 4A).

Nyctiophylax (Paranyctiophylax) crinalis n. sp. (Fig. 1) Diagnosis. This new species is very similar to N. suthepensis Malicky & Chantaramongkol 1993 from Thailand. It differs in that Nyctiophylax (Paranyctiophylax) crinalis n. sp. has the inferior appendages with their inner margins each bearing a row of long strong setae in ventral view, its basomesal setose lobe is semicircular in both lateral and ventral views and in ventral view this lobe is strongly sclerotized and broader than its main body. On the other hand, N. suthepensis has the inner margin of each inferior appendage without a row of long strong setae and the basomesal setose lobe is oval in ventral view and narrower than its main body. Another difference between the two species is that the phallus of the new species has a pair of long, needle-like parameres, at least as long as the phallus, and the phallicata is without any short spines, while N. suthepensis has thick parameres only half as long as the phallus and the phallicata has some additional short spines. Male. Length of each forewing 4.2–4.8 mm (N=16). Head light brown with dark yellowish antennae, pronotum light brown, meso- and metanota brown with warts light brown, forewings brown. Male genitalia. Sternum IX in lateral view nearly quadrangular, posterior margin protruding at middle and forming 135° angle (Fig. 1A); in ventral view anterior margin excised in U-shape with depth of 1/3 length of sternum, posterior margin with broad and very shallow concavity (Fig. 1C); dorsal region of tergum IX membranous, trapezoidal (Fig. 1B). Preanal appendages broad at base in lateral view, each approximately 2 times its middle width, apex obliquely truncate; basal half of mesoventral process broad, distal half acute and horn-like, directed downward. Tergum X long and tongue-like in lateral view; transparent, semi-sclerotized, with V-shaped incision apicomesally in dorsal view (Fig. 1B). Inferior appendages each about 7 times as long as its mid width in lateral view, slightly clavate, narrowed at middle, with basomesal setose lobe semicircular in lateral view (Fig. 1A); in ventral view each inferior appendage nearly parallel-sided, with inner margin bearing row of long thick setae, basomesal setose lobe strongly sclerotized, semicircular, broader than main body, with rounded apex (Fig. 1C). Phallus tubular, with pair of compressed oval protrusions laterally near middle; pair of parameres long, needle-like; phallicata without spines. Holotype male. Guang-xi Province: Shang-si County, Mt.

Nyctiophylax (Paranyctiophylax) adaequatus Wang & Yang 1997 (Fig. 5) Nyctiophylax (Paranyctiophylax) adaequatus Wang & Yang 1997 (in Yang et al. 1997): 284–285, 287–288, fig. 6 (male). Type locality: Henan (Song-xian Co., Mt. Bai-yun-shan N34.08°, E112.05°). Remarks. Additional field collections and laboratory identifications have brought us more specimens of this species. These specimens from other parts of China show interesting variations, possibly with a geographical cline, especially in the shape of the inferior appendages. The holotype also is redrawn here for comparison. In each inferior appendage of the holotype, the basomesal lobe is only slightly shorter than the dorsal branch of the main body in lateral view (Fig. 5E), with a narrow apex and an obviously angled mesal protrusion in ventral view (Fig. 5F). Material from Gui-zhou shows a similar pattern. However, in a specimen from Guang-dong (southern China) the basomesal lobe is obviously shorter than the dorsal branch of the main body of each inferior appendage in lateral view (5A), with a blunt tip and the mesal projection not so distinctively angled (Fig. 5B). These characters are also variable individually in the same collection (Fig. 5C). In specimens from Qin-ling (northern China), the basomesal lobe is slightly shorter than the dorsal branch of the main body of each inferior appendage as for the holotype, but with a more acute apex and the mesal projection is not so distinctively angled in ventral view (Fig. 5H).
