Antenna approximately mm long. Pronotum (Fig. 55) approximately times as long as broad and times as broad as head; punctation dense and non-umbilicate, much coarser than that of head; in- terstices glossy, fomiing narrow ridges; midline punctate in anterior half, impunctate and narrowly elevated in pos- terior half. Elytra (Fig. 55) approximately times as long as pronotum; humeral angles obsolete; punctation similar to that of pronotum; interstices glossy. Hind wings complete- ly reduced. Abdomen approximately times as broad as elytra; punctation dense, defined, and coarse on tergites IIl-Vl, much finer and sparser on tergites Vll and VUl than on tergite VI; interstices without microsculpture and glossy; posterior margin of tergite VII without palisade fringe; posterior margin of tergite VIll strongly convex. S'- sternite Vll (Fig. 56) with posterior margin very weakly concave in the middle, otherwise unmodified; ster- nite VIII (Fig. 57) weakly transverse, posterior excision small and V-shaped; aedeagus (Fig 58-60) approximate- ly mm long; ventral process short, apically acute in Bonn zoological Bulletin 62 (2): 125-170 ventral view, and laterally somewhat compressed; dorso- lateral apophyses long and slender, distinctly extending be- yond apex of ventral process. Comparative notes. Based on the shapes and chaetotaxy of the male sternite VII and VIII, as well as on the mor- phology of the aedeagus (short ventral process; long and slender dorso-lateral apophyses), A^. wiiliangicus is close- ly allied to N. daliensis, from which it differs particular- ly by the more slender dorso-lateral apophyses of the aedeagus. It is reliably distinguished from the geograph- ically close TV. barbatus, which too was found only in the Wuliang Shan, only by the completel
