Plectrocnemia punjabica Group Li 1998 Li (1998) recognized one synapomorphy for this group: Inferior appendages slender, each with a “basodorsal tooth.” To this, we added: The basodorsal tooth usually is long, hook-like. We label this structure as the basodorsal process of an inferior appendage. In addition, the inferior appendages each always has a setose basomesal lobe. The members of this group also share the following diagnostic characters: The parameres of the phallus are absent and the inferior appendages are without ventromesal processes, mesal plates, and digitate processes. Plectrocnemia fanjingensis Zhong, Yang & Morse, sp. nov. (Fig. 6) Adult. Length of each male forewing 6.7–7.5 mm (N = 3). Head of specimens in alcohol brown with pale yellowish antennae, pronotum yellowish, meso- and metanota brown with yellowish warts, wings brown. Male genitalia. Sternum IX highly sclerotized, in lateral view (Fig. 6 B) ventral half long, its anterior margin protruding, round, and its posterior margin abruptly protruding, truncate; subdorsal half short, forming narrow transverse band, posterior margin incised in ~ 100 ° angle between subdorsal half and ventral half; in ventral view (Fig. 6 A), anterior margin with small V-shape incision and posterior margin slightly protruding at middle; tergum IX semi-membranous, tongue-like in dorsal (Fig. 6 C) and caudal (Fig. 6 F) views. Tergum X slightly sclerotized, with mesal incision in dorsal view (Fig. 6 C), lateral margins slightly thickened and each with slender digitate projection bearing 2–3 setae apically. Intermediate appendages long and broad, highly sclerotized, each with hooked apex directed laterad (Fig. 6 C). Preanal appendages each narrow at base, gradually expanding to broad apex with apical margin irregularly incised and approximately 3 times as wide as base (Figs. 6 B, 6 C). Inferior appendages long and parallel-sided, ~ 6 times as long as average width in lateral view (Fig. 6 B), each with its distal half evenly curved dorsad and with thick hook on basodorsal edge; mesobasal setose lobe present; in ventral view (Fig. 6 A), broad at base, each with distal 3 / 4 ths gradually narrowed to blunt apex. Phallus with phallobase long and slightly sclerotized, phallicata short, semi-membranous, with pair of phallic sclerites slender, embracing phallotremal sclerite and with their distal halves fused to each other; parameres absent (Figs. 6 D, 6 E). This new species is very similar to P. tsukuiensis (Kobayashi 1984), from Japan. It differs in the following characters: 1) Preanal appendages are expanded apically, each with its broad apical margin irregularly incised (broadest at middle, gradually narrowing to blunt apex in P. t s u k u i e n s i s); 2) tergum X has slender, digitate lateral projections, and intermediate appendages do not extend beyond the preanal appendages in lateral view (without digitate projections and intermediate appendages extending beyond preanal appendages in P. tsukuiensis); 3) sternum IX is as tall as long in lateral view and its anterior margins are strongly protruded forward in a semicircle (gently protruded anteriorly and taller than long in lateral view in P. t s uk u ie n s is). Holotype male: Gui-zhou Province: Mt. Fan-jing, N 27.55 °, E 108.41 °, Yu-ao, alt. 900 m, 4 June 1995, Coll. Sun C-h. and Wang B-x. Paratype: Same data as holotype, 2 males. Etymology. The species name is derived from “Mt. Fan-jing,” the type locality of this new species. Distribution. China (Gui-zhou). Plectrocnemia platilobus Zhong, Yang & Morse, sp. nov. (Fig. 7) Adult. Length of each male forewing 6.4–7.5 mm (N = 6). Head of specimens in alcohol brown with dark yellowish antennae, pronotum dark yellowish, meso- and metanota brown with yellowish warts, wings brown. Male genitalia. Sternum IX highly sclerotized, ventral half with anteroventral bulge subrectangular and subdorsal sclerotization produced dorsad in acute angle in lateral view (7 B); in ventral view (Fig. 7 A), anterior margin slightly incised, posterior margin broadly excised; tergum IX weakly sclerotized, broadly triangular in dorsal view (Fig. 7 C). Tergum X semi-membranous. Intermediate appendages highly sclerotized, horn-like in dorsal view (Fig. 7 C), each stout in basal 3 / 4 ths and with acute apex in lateral view (Fig. 7 B), in caudoventral view (Fig. 7 E) each with small cylindrical projection bearing apical seta. Preanal appendages broadly foliaceous, approximately as long as wide, each with apicodorsal end produced in acute process in lateral view (Fig. 7 B). Inferior appendages broad basally, gradually reducing to narrow apices, each with dorsal margin slightly protruding near middle in lateral view (Fig. 7 B); in ventral view (Fig. 7 A), each appendage with small setose lobe basomesally, distal 3 / 5 ths of each appendage digitate and angled mesad; basodorsal process slender, falciform in ventral view (Fig. 7 A), curved mesad, with narrow apices of opposing processes tilted and crossing each other. Phallus thick, tubular; phallobase and phallicata both sclerotized; pair of phallic sclerites blade-liked in lateral (Fig. 7 D) and ventral (Fig. 7 F) views; parameres absent. This new species is very similar to P. acanthos Mey 1996 from Vietnam. The male differs from that of P. acanthos in the following characters: 1) Preanal appendages each have an acute process on its apicodorsal end in lateral view (without any protrusions in P. acanthus); 2) the intermediate appendages each has a small cylindrical process on its outer margin, this process bearing an apical seta (without any projection in P. acanthus); 3) the inferior appendages are slightly elbowed in ventral view and the basodorsal process of each inferior appendage is slender and falciform in lateral view (not elbowed in ventral view, and each with its basodorsal process triangular in lateral view in P. acanthus).

Distribution. China (Si-chuan). Plectrocnemia paragryphalis Zhong, Yang & Morse, sp. nov. (Fig. 8) Adult. Length of each male forewing 5.6 mm (N = 1). Head and antennae of specimen in alcohol brown, pronotum yellowish, meso- and metanota brown with yellowish warts, wings brown. Male genitalia. Sternum IX highly sclerotized, ventral half subtriangular and with dorsal margin forming narrow angle in lateral view (Fig. 8 B); in ventral view (Fig. 8 A), anterior margin excised in wide V- or U-shape and posterior margin broadly concave with slight mesal protuberance; tergum IX slightly sclerotized, long, trapezoid in dorsal view (Fig. 8 C). Tergum X semi-membranous, with deep apicomesal incision, each apical half with 2 stout setae apicolaterally (Figs. 8 C, 8 D). Intermediate appendages highly sclerotized, long and needle-like, with broad bases embracing phallobase lateroventrally in ventral view (Fig. 8 D). Preanal appendages foliaceous in lateral view (Fig. 8 B), each broad at base, triangular apically; its mesoventral process large, directed horizontally caudad in lateral view (Fig. 8 B); in ventral view (Fig. 8 D), each with its basal half expanded mesad and meeting its opposite under phallus. Inferior appendages long, evenly cylindrical, and constricted distally in blunt apices; basodorsal process of each appendage hooked, about 2 times as tall as wide, basally erect and then directed caudad, much larger and taller than basal setose lobe in lateral view (Fig. 8 B); in ventral view (Fig. 8 A), most of basal setose lobes visible, but basodorsal processes not visible. Phallus tubular, broad at base, without parameres (Fig. 8 E). The new species is very similar to P. gryphalis Mey 1996 from Vietnam. The male differs from that of P. gryphalis in the following characters: 1) The inferior appendages are long and evenly cylindrical, with narrow, round apices (broadly swollen in the basal half and with the distal half slender and sinuate in P. g r y p h a l i s); 2) the basodorsal process of each inferior appendage is thick, hooked, and much larger and taller than the basal setose lobe in lateral view, in ventral view most of the basal setose lobe is visible, (the basodorsal process is small, only as tall as the basal setose lobe in lateral view, in ventral view the basal setose lobe is not visible in P. gryphalis).
