See Grichanov (2013) for diagnosis of the genus. Grichanov (2013) recognised four subgenera of the genus, i.e. Diostracus Loew, 1861, Sphyrotarsus Mik, 1874, Lagodechia Özdikmen, Negrobov et Tsurikov,, 1995) and Wang</p> <p>1996, and Ozmena 2010. Saigusa (1984 et al. (2015) distinguished nine species groups inhabiting Myanmar, Nepal and Tibet. A new species is described and illustrated here. Diostracus campsicnemoides sp. n. from the Yunnan Province of China belongs to the subgenus Diostracus (sensu Grichanov, 2013), or to the tangalensis species group (sensu Wang et al., 2015) comprising single species D. tangalensis Saigusa, 1984 known from Nepal. The last species is associated here with the subgenus Diostracus for the first time.</p> </div>	https://treatment.plazi.org/id/396C87DDFFD3270A2270FA7EFE35FE1E	Public Domain	No known copyright restrictions apply.

G. Davidian [ZIN].</p> <p>DIAGNOSIS. According to Grichanov (2013), the new species belongs to the nominotypical subgenus Diostracus Loew, 1861, differing from other subgenera in the presence of several dorsal setae on antennal scape. Following the key to Chinese species (Yang et al., 2011), the new species is close to D. nishiyamai Saigusa, 1995, which has glabrous scape, mostly black tibiae and tarsi, short cercus, etc. Following the key to Himalayan and Tibetan species (Wang et al., 2015), the new species keys to D. (Diostracus) tangalensis Saigusa, 1984, which has also setose antennal scape, but differing from D. (D.) campsicnemoides in blackish legs, short setose four leg, short fore basitarsus, and small triangular cercus.</p> <p>DESCRIPTION. Male.
