Pacheco, Thaynara L., Ahrens, Dirk (2023): Addendum to the revision of the South American genus Symmela Erichson, 1835 (Coleoptera: Scarabaeidae: Melolonthinae: Sericini): a further new species from Brazil. Zootaxa 5263 (2): 297-300, DOI: 10.11646/zootaxa.5263.2.8, URL: http://dx.doi.org/10.11646/zootaxa.5263.2.8

Three new species of the genus Brachyllus Brenske, 1896 are described from China including Brachyllus songhaitiani Zhao, Qi, Su & Liao, new species from Fujian and Jiangxi, B. dongzhiweii Zhao, new species from Xizang and B. tangzhaoyangi Zhao, new species from Guangxi. Brachyllus langeri Keith, 2008 is downgraded to a subspecies of B. rougeriei Keith, 2003 and reported from China for the first time. Newly collected material of B. deuveianus Keith, 2003 allows better definition of its variability. A distribution map for this genus is also presented.

Seven species of Maechidius Macleay, 1819 from New Guinea are described, namely M. addarcis Prokofiev, new species, M. astrolabius Prokofiev, new species, M. bombycinus Prokofiev, new species, M. echinoides Prokofiev, new species, M. macrosoma Prokofiev, new species, M. penicilliger Prokofiev, new species, and M. telnovi Prokofiev, new species. Males of M. interruptocarinulatus Heller, 1914 and aedeagus of M. seriepunctatus Moser, 1920 are described for the first time. Key to the Indonesian and New Guinean species is amended for inclusion of the newly described species.

In this paper we revised the species of Serica McLeay, 1819 (sensu lato) occurring in China an adjacent areas, and provide an update on the genus Nipponoserica Nomura, 1972. The revision resulted in one new combination: Serica adspersa (Frey, 1972), new combination.

Female unknown. Collecting circumstances. At light. Differential diagnosis. Melolontha lachungensis new species differs from the other two species in the group (M. phupanensis and M. arunachalensis new species) by the unique structure and shape of the parameres and unidentate protibiae. See species key and Table 1 to distinguish it from M. phupanensis and M. arunachalensis new species. The newly described species also shows similarities in general appearance to Melolontha costipennis Fairmaire, 1889 (= M. tricostata Brenske, 1903) and M. tenuicauda Fairmaire, 1896, both of which are known from China (Tibet). Melolontha costipennis, placed under the aeneicollis group (Li et al. 2010), differs from the new species by a narrowly elongated pygidium at the apex (pygidium rounded at apex, not elongated in M. lachungensis new species). Melolontha tenuicauda has a much shorter antennal club, as compared to M. lachungensis new species. Etymology. The name (adjective in the nominative singular) refers to the type locality, Sikkim.

Refer to the key to species groups. Distribution. India: Arunachal Pradesh (new record); China (Guérin-Méneville 1838) and Vietnam (Dalla Torre 1912). Remarks: Guérin-Méneville (1838) described this species from China with the following characteristics: body more or less flattened, elytra dark yellow with striae less marked, ventral portion black with dense and long whitish hairs, mesometasternal process straight, directed forward and rounded at the end, and antennae black, similar in both sexes. Dalla Torre (1912) reported this species from Tonkin (Vietnam). Li et al. (2010, fig. 15) noted that the parameres in the chinensis group have sharply pointed dorsal processes, surpassing the outer margin. Our record of M. chinensis from Arunachal Pradesh, India, is quite distant from the known distribution range of this species.

Holotype, male, labelled: “ India, Arunachal Pradesh, Pange Valley, 27°13'15.024''N, 93°10'40.6128''E, 11.iv.2015, leg. K.A. Subramaniam ” [NZSI]. Paratypes: 3 males with the same data as holotype [NZSI]. Description of the holotype. Body length: 28.15 mm; maximum body width 15.35 mm. Colour. Pronotum, scutellum, venter, and legs dark brownish-black. Elytra reddish - brown. Setae whitishyellow. Head (Figs. 25–26). Clypeus rectangular, apical angles rounded, slightly widened apically, apex perpendicularly reflexed, moderately sinuate in frontal view, surface concave medially, lateral angles planar, surface densely and evenly punctate, punctures large, each bearing a short, robust, erect seta, setae light yellowish-brown; clypeofrontal suture complete; centre of frons concave, surface densely setose, side of eyes densely setose, setae moderately longer and more robust than those on clypeus; sides slightly narrowed making eyes larger. Antennae 10 segmented with 7 segmented club, lamellae strongly curved outwardly, 3.62 times as long as stem; antennomere 1 distinctly swollen apically, apical segment moderately elongate; labrum symmetrically bilobed, each lobe transversally developed; mentum slightly concave centrally, surface almost glabrous with only a few scattered setae; maxillary palpus with apical palpomere subequal in length to combination of palpomeres 2–3; ocular canthus heavily covered with brownish erect robust setae. Pronotum (Fig. 27). Transverse, widest at middle, basomedially slightly protuberant posteriorly; surface densely to confluently punctate along lateral margin; punctures moderately large with a tiny, brownish seta, setae longer and more robust towards centre; centre of pronotal disc sparsely punctate; sides of midline setose with spot consisting of concentrated brownish setae on each apical side of midline; setae denser along basomedial margin; serration of lateral margin distinctly developed, basal half of margin with completed bead. Scutellar plate (Fig. 28). Oval, surface lightly, sparsely punctate, two longitudinal rows of setae fused at point making a triangle, apical margin has a row of slender hair-like setae. Elytra (Fig. 3). Broadest at base. Costae 1–3 (costa one as sutural costa) glabrous and well developed, costae 2 and 3 broadly fused on apical umbone, costa 4 feebly developed and hardly observable; outer margin of costa 1 with aligned row of whitish, scale - like setae; intervals rugose, intermixed with two kinds of whitish setae, one lanceolate and scale - like and other slender and smaller, both moderately dense in distribution; posthumeral and 3 basal patches composed of overlapping, white, scale - like setae, posthumeral patch slender in shape; apical area of elytron steeply depressed below plane of disc, densely covered with whitish brown, tiny setae; epipleuron entirely setose, whitish brown setae evenly distributed; humeral umbone moderately swollen. Pygidium (Fig. 15). Triangular, 1.6 times wider than long; anterior half with long; disc either side slightly depressed medially; surface densely covered with whitish brown setae; setae short evenly distributed or moderately scattered along midline; apex rounded; lateral margin straight. Venter (Fig. 30). Mesometasternal process produced beyond mesocoxae, surface smooth with few hairs; meso- and metasternum with thick, dense hairs. Abdominal sternites (Fig. 32). Abdominal segments 1–5 with a lateral maculation of yellowish-brown, scalelike setae; maculation on sternite 6 light; abdominal surface densely setose; setae whitish brown to yellowish–brown, lanceolate, slender medially, transversely distributed with scattered, longer setae in line; sternites 2–5 weakly fused medially; suture well defined. Legs (Figs. 29, 31). Protibiae bidentate laterally, apical tooth acute (Fig. 29); tarsal claws symmetrically unidentate, abruptly curved apically with a small, vertical tooth at base. Pro- and mesofemora transversely flattened, surface densely clothed with long, hair-like, brown setae; metafemur stout, with shorter setae; apical portion of first metatarsus distinctly swollen; outer metatibial spur subequal in length to combined length of metatarsomeres 1 and 2 (Fig. 31); dorsal surface of tibiae and tarsi moderately clothed with pale white, scale-like, short robust setae; meso- and metatibiae with two elongate apical spurs; mesotibial spurs slightly shorter than length of mesotarsomere 1. Parameres (Figs. 43, 55). Symmetrical; basal piece subequal in length to paramere; lobes of parameres nearly straight at apex, slightly pointed at ends in dorsal view (Fig. 43), strongly curved, bent backwards at apex in lateral view (Fig. 55); dorsal process, clearly marked, slightly produced (Fig. 43), ventroapical process distinctly elongate and gradually acuminate apically with a small, crest-like protuberance on top of right paramere in lateral view (Fig. 55). Female unknown. Collecting circumstances. At light. Differential diagnosis. Melolontha arunachalensis new species differs from the other two species in the group (M. phupanensis and M. lachungensis new species) by its unique structure and shape of the parameres. See species key and Table 1 to distinguish the newly described species from M. phupanensis and M. lachungensis new species. The newly described species is similar in general appearance to Melolontha costipennis Fairmaire, 1889 (= M. tricostata Brenske, 1903) and M. tenuicauda Fairmaire, 1896, both of which are known from China (Tibet). Melolontha costipennis, placed under the aeneicollis group (Li et al. 2010), differs from the new species by a narrowly elongated pygidium at the apex (pygidium rounded at apex, not elongated in M. arunachalensis new species). Melolontha tenuicauda has a much shorter antennal club, as compared to M. arunachalensis new species. Etymology. The name (adjective in the nominative singular) refers to the Arunachal Pradesh state of India. Distribution.

Amphimallon alexandri Uliana & Montreuil, new species, is described from continental Greece, near Volos. The species has diurnal activity and is close to A. arianae (Fairmaire, 1879), A. krali Montreuil, 2002, and A. spartanum (Brenske, 1884), but is well characterized and easily distinguished from all of them by several morphological characters. Detailed comparative illustrations of the main diagnostic traits of the new species and the most similar one (A. krali) are provided. After reviewing the available information, Amphimallon atrum is removed from the Greek fauna.

Male genitalia. As in Fig. 7I–J. Female. Unknown. Measurements. Body length (measured from anterior margin of clypeus to apex of elytron): 15.3 mm, body width (measured across humeri): 6.6 mm. Differential diagnosis. Brachyllus dongzhiweii Zhao, new species is most similar to B. frontalis Brenske, 1896 (Fig. 3C–D). The new species can be easily separated from B. frontalis by the shorter antennal club, which is equal to the combined length of antennomeres 3–4 but of antennomeres 3–6 in the latter species (Fig. 4A–B). The setae on lateral portions of abdominal ventrites are stouter (Fig. 4C–D). The elytra of the new species bear some short setae, while short setae are almost imperceptible on elytra of B. frontalis (Fig. 4E–F). Moreover, the shape of parameres differs a lot in lateral view: in B. dongzhiweii new species, the dorsal concavity is much shallower and the upper lobe is rounded ventrally, the lower lobe distinctly protruding. B. frontalis has deep dorsal concavity, ventrally protruding upper lobe and weakly protruding lower lobe (Fig. 7I–L). Other two Himalayan congeners, B. ulcerosus Brenske, 1896 and B. bhutanensis Keith, 2005 are also similar. But the two have a distinctly opaque and uneven pronotum, in contrast to the shiny and less uneven in B. dongzhiweii new species and B. frontalis. Etymology. This species is dedicated to Zhi-Wei Dong, who collected and donated the holotype of this new species., Published as part of Zhao, Ming-Zhi, Qi, Zhi-Hao, Su, Rong-Xiang & Liao, Tao-Kun, 2023, New and poorly known species of the genus Brachyllus Brenske, 1896 (Coleoptera Scarabaeidae: Melolonthinae) from China, pp. 358-370 in Zootaxa 5256 (4) on pages 361-364, DOI: 10.11646/zootaxa.5256.4.4, http://zenodo.org/record/7755194, {"references":["Keith, D.

Brachyllus rougeriei langeri Keith, 2008 new status (Figs. 3E–F, 4H, 7G–H) Brachyllus langeri Keith, 2008: 321 [original description]. Type material examined. None. Additional material examined. 1♁ (ZMPC), CHINA: Yunnan, Dehong Pref., Longchuan County, Mt. Banggunjianshan, 1600 m, 2022.VIII.11, Yu-Chen Zheng, Zu-Qi Mai & Yue-Zheng Tu leg. Remarks. An additional specimen of B. langeri was collected from Mt. Banggunjianshan, circa 160 km southwest to Panwar, the type locality. When describing B. langeri, Keith (2008) did not compare it with B. rougeriei Keith, 2003. However, the authors noticed a close resemblance between the two taxa. In B. langeri, general body color is more blackish, punctures on pronotum are slightly denser and apex of paramere is somewhat truncated in lateral view (rounded in B. rougeriei).

Paratypes: 1 Ô, 1 ♀ “ Hte Birmanie Mines des Rubies 1200-2300m Doherty 1890 / Museum Paris ex. Coll. R. Oberthur ” (MNHN, ZFMK). Description of holotype. Length: 7.2 mm, length of elytra: 5.4 mm, width: 4.4 mm. Body oblong-oval, dark reddish brown, elytra and antennal funiculus yellowish brown, elytral margins and one transversal mesolateral spot dark brown, dorsal surface dull or partly with iridescent shine, nearly glabrous. Labroclypeus little wider than long, shiny, widest at base, lateral margins strongly convex and convergent to convex anterior angles; anterior margin deeply emarginate medially, margins moderately reflexed; lateral margins and ocular canthus produce a blunt angle; surface convex, coarsely and densely punctate, with numerous long, erect setae; frontoclypeal suture finely incised and curved medially. Frons entirely shiny, with irregularly dense, fine punctures, beside eyes with some long setae, otherwise glabrous. Smooth area in front of eyes flat, twice as wide as long. Ocular canthus narrow and moderately long (1/3 of ocular diameter), almost impunctate, with a terminal seta. Eyes moderately large, ratio of diameter/interocular width: 0.73. Antenna with ten antennomeres; club composed of four antennomeres, straight, as long as than remaining antennomeres combined. Mentum elevated and slightly flattened anteriorly. Pronotum moderately wide, widest at base, lateral margins in basal half straight and distinctly convergent, anteriorly moderately convex and convergent towards sharp and produced anterior angles; posterior angles blunt. Anterior margin of pronotum weakly convex, with fine but medially widely interrupted marginal line; basal marginal line absent; surface finely and densely punctate, glabrous, with minute setae in punctures; setae of lateral and anterior margins sparse, not extending on pronotal disc around anterior angles. Hypomeron carinate, weakly produced ventrally. Scutellum triangular, finely and densely punctate, glabrous. Elytra elongate, widest at middle, striae weakly impressed, finely and densely punctate; sutural interval and lateral 2–3 intervals dark, dark color on elytra on mesal intervals near scutellum extended, as behind middle on sublateral intervals; intervals weakly convex, with fine and sparse punctures, with minute setae in punctures, penultimate lateral interval with a few short setae; epipleural edge fine, ending at weakly rounded, and almost blunt external apical angle of elytra, epipleura sparsely setose; apical border narrowly membranous, with a fine rim of short microtrichomes (magnification 100x). Ventral surface dull, finely and densely punctate, metasternum sparsely covered with fine, short, or very minute setae; metacoxa glabrous, with a few single setae laterally. Mesosternum between mesocoxae as wide as mesofemur. Ratio of length of metepisternum/metacoxa: 1/1.59. Abdominal sternites finely punctate, with a transverse row of coarse punctures, each bearing a robust seta. Pygidium weakly convex and dull, with dense, coarse punctures but without smooth midline, with a few longer setae along apical margin. Legs almost slender and long; femora finely and sparsely punctate, with two longitudinal rows of longer setae. Metafemur moderately shiny, anterior margin acute, without submarginal serrated line; anterior row of seta-bearing punctures present; posterior margin smooth ventrally, not serrate, widened in apical half, posterior margin smooth dorsally, with a few short setae basally. Metatibia moderately long and wide, widest at middle, ratio of width/ length: 1/3.55; dorsal margin weakly carinate in apical half, in basal half longitudinally convex, with two groups of spines, basal group at shortly before middle, apical one at three quarters of metatibial length, in basal third without further robust setae; lateral face longitudinally convex, finely and sparsely punctate, sometimes with minute setae in punctures; ventral edge finely serrate, with three robust equidistant setae; medial face smooth, apex interiorly near tarsal articulation shallowly concavely truncate. Tarsomeres with fine, sparse setae ventrally, neither laterally nor dorsally carinate, dorsally smooth; metatarsomeres glabrous, with a strongly serrated ridge ventrally and a parallel subventral smooth carina immediately beside it; first metatarsomere little shorter than following two tarsomeres combined, distinctly longer than dorsal tibial spur. Protibia short, bidentate; anterior claws symmetrical, basal tooth of both claws bluntly truncate at apex. Aedeagus: Fig. 23A–C. Habitus: 23D. Diagnosis. Oxyserica bifascipennis Ahrens, Lukic & Liu, new species resembles in external appearance the O. marginata (Brenske, 1898), while in shape of aedeagus it is similar to O. nigropicta (Fairmaire, 1891) and O. diversicornis (Moser, 1915). Oxyserica bifascipennis Ahrens, Lukic & Liu, new species differs from all of them by the larger body size, and, of course, in shape of parameres: the distal margin of phallobase (lateral view) is reflexed, the ventral lobes of parameres which are in the new species as well as in O. nigropicta and O. diversicornis subsymmetric, are longer than half of the phallobase in Oxyserica bifascipennis. Etymology. The name of the new species is derived from the combined Latin prefix “ bi ” (two-), and the words “ fascis ” (stripes) and “ pennis ” (wing). Variation. Length: 7.0– 7.2 mm, length of elytra: 5.1–5.4 mm, width: 4.3–4.4 mm.
