Pronotum with fore margin yellowish-brown, midline and hind margin of pronotum grey bordered with dark brown. Brochosome field of forewing grey. Crown fore margin rounded in dorsal view, anteclypeus ovoid. Hind wing ( Fig. 4b ) with av almost complete between AP’+AA and CuP. Male 2S abdominal apodemes ( Fig. 4c ) not extended to hind margin of sternite IV. Anal tube appendage ( Fig. 4d ) very short and weakly sclerotized. Pygofer lobe ( Fig. 4d ) with group of macrosetae in middle area and some fine setae near ventral and caudal margins; dorsal appendage ( Fig. 4e ) thick, apex pointed and sharply bent cephalad. Subgenital plate ( Fig. 4g ) with about 6 macrosetae, apical ones much thinner than basal ones, with row of microsetae along outer margin. Style ( Fig. 4h ) stout, apical part thick and straight. Connective ( Fig. 4i ) with manubrium very narrow, lateral arms horizonal, in a line. Aedeagal shaft ( Figs 4j, k ) almost straight, dorsal and lateral margins serrated, apex blunt in lateral view, widened basally and tapering towards apex in ventral view; dorsal apodeme well developed, narrow and long in lateral view; preatrium as long as shaft, widened near preatrial process, process narrow and long; gonopore middle on ventral margin. Diagnosis. The new species has av of hind wing developed basally (between AP’+AA and CuP), which is similar to Diomma ( Diomma ) knighti Dworakowska, 1981 , but different with most other species in Diomma . The male genitalia of the new species is very close to Diomma ( Diomma ) pincersa Song, Li & Xiong, 2011 , but the pygofer dorsal appendage is bent cephalad, the subgenital plate is much wider and has a straight outer margin, the style has shorter, thicker apical part and the lateral arms of the connective are shorter. Measurement. Male length 2.70mm. Material examined. Holotype : ♂ , CHINA , Hunan Prov., Sangzhi , 0 6 ix 1981 , coll. Xinwang Tong. Etymology. The new species name is an adjective referring to the type locality, Sangzhi.
