CHINA : Guizhou Province , Dashahe Natural Reserve Area , 5 males , 24.viii.2004 , light trap , X. Yu . Diagnostic characters. The species can be separated from other members of the subgenus by having AR 2.5– 3.0, anal lobe strongly produced, inferior volsella with dorsal part broadly rounded and overlying the ventral part, and virga consisting of two main spines. Remarks. O. ( O. ) glabripennis was once treated as a junior synonym of O. ( Pogonocladius ) consobrinus (Holmgren) by Brundin (1956) . However, Pinder & Cranston (1976) gave a detailed comparative description of the two species, and proved the validity of both names. Wang et al . (2005) recorded the species from Guizhou Province .
