Notes. Eremus rugosifrons, the type species of Eremus Brunner von Wattenwyl, 1888 . It bears characteristics that most species of Eremus contain: face rugose; head rather wide, fastigium vertics more than twice as wide as scapus (Fig. 1D); wings absent; the male’s ninth abdominal tergite smooth, and the apical margin bearing a pair of short spines (Fig. 1E).

Karny (1929a) described the female morphology of this species by two female specimens: one from Sikkim, the other without locality label. Ingrisch (2018) mentioned that these specimens may not be Eremus rugosifrons, since the localities were rather imprecise. The two female specimens are not regarded as E. rugosifrons in this study.

Distribution. Only known distributed from China.
