Genus Drepasiagonusa View in CoL PACE, 2012

According to the original description, the genus is characterized by the shape of the mandibles ( Figs 11 View Figs 10-21 , 37 View Figs 33-39 ), an elongated spermatheca ( Figs 5 View Figs 1-9 , 20-21 View Figs 10-21 , 31-32 View Figs 22-32 , 39 View Figs 33-39 ), and an apically divided and strongly sclerotized ligula ( Fig. 12 View Figs 10-21 ). The remaining characters indicated by PACE (2012) apply to the majority of Palaearctic genera of Oxypodini View in CoL . Based on the species studied in the course of the present study, additional characters are a large head (in relation to the pronotum) and the shape of the antennae (fine; weakly incrassate at most).

Material of seven species, six from China and one from East Russia, was examined. Four species are newly described. Two species with weakly distinctive external characters from the Chinese province Shaanxi remain undescribed for want of males. The spermatheca of Drepasiagonusa species is of rather uniform shape (little interspecific variation) and consequently of little use for taxonomic purposes.
