M. Schülke [CH09-23] / Holotypus ♀ Drepasiagonusa procera sp.n. , det. V . Assing 2018" (MNB). E t y m o l o g y: The specific epithet (Latin, adjective: slender) alludes to the distinctive habitus of this species. D e s c r i p t i o n: Body length 4.2 mm ; length of forebody 2.0 mm. Habitus as in Fig. 6 . Coloration: forebody reddish; abdomen reddish with most of tergite VI, the anterior two-thirds of tergite VII, and an antero-median spot on tergite III-V blackish; legs, antennae, and maxillary palpi reddish. Head ( Figs 7 , 37 ) approximately as long as broad; punctation shallow, rather large, and extremely dense (except on frons), with the interstices reduced to narrow ridges; microsculpture pronounced. Eyes moderately convex and small, little more than half as long as distance from posterior margin of eye to posterior constriction of head. Antenna ( Fig. 8 ) 1.3 mm long and very slender; antennomeres IV approximately twice as long as broad, V-X of gradually decreasing length and decreasingly oblong, X weakly oblong, and XI approximately as long as the combined length of IX and X. Mandibles ( Fig. 37 ) each with a pronounced, long and acute molar tooth. Pronotum ( Fig. 7 ) weakly transverse, 1.08 times as broad as long and approximately as broad as head, broadest in the middle; lateral margins distinctly convex in the middle and sinuate near posterior angles (dorsal view); punctation and microsculpture similar to those of head, but punctures even shallower and less defined. Elytra ( Fig. 7 ) 0.85 times as long as pronotum; punctation extremely dense, moderately fine, and defined. Hind wings not examined. Metatarsomere I approximately as long as the combined length of metatarsomeres III and IV. Abdomen ( Fig. 9 ) as broad as elytra; tergites III-V with moderately deep anterior impressions, tergite VI without anterior impression; punctation fine and dense, only slightly sparser on tergite VII than on anterior tergites; interstices with distinct microreticulation; posterior margin of tergite VII with palisade fringe; posterior margin of tergite VIII weakly convex. ♂ : unknown. ♀ : posterior margin of sternite VIII obtusely produced in the middle ( Fig. 38 ); spermatheca shaped as in Fig. 39. C o m p a r a t i v e n o t e s: Drepasiagonusa procera is readily distinguished from all other species of the genus by its conspicuous external characters alone: relatively large body size; slender habitus; a reddish forebody; long and very slender antennae with oblong antennomeres IV-X; small eyes; short elytra. D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The type locality is situated near Gongshan in the Gaoligong Shan, Northwest Yunnan . The holotype was sifted from wet moss near a small waterfall at an altitude of approximately 2900 m .
