Dicraeus flavipes Duda, 1930

Dicraeus flavipes Duda, 1930 .: 295. Type locality: China: Taiwan.

Description. Head brown; frons slightly longer than wide, anterior 1/4 of frons yellow; gena broad, 0.25 times as deep as eye. Ocellar triangle smooth, shiny, reaching anterior margin of frons, with pointed apex. Palpus largely black. Thorax black. Legs yellow except for fore and mid tarsomeres 2–5 and hind tarsomeres 3–5 black. Wing hyaline, veins brown. Relative lengths of 2nd: 3rd: 4th costal sections = 6.6: 1.4: 1. Male genitalia: Epandrium yellow, surstylus 0.7 times as long as depth of epandrium in lateral view, clavate in form, gradually widened toward apex, round distally ( Kanmiya 1971).

Distribution. China (Taiwan).

Remarks. The species is somewhat similar to D. nartshukae Kanmiya, 1971 , but can be separated from the latter by the following features: gena 0.25 times as deep as eye in lateral view; palpus largely black; surstylus clavated in lateral view. In D. nartshukae , the gena is 0.3–0.4 times as deep as eye in lateral view; the palpus is entirely yellow; and the surstylus is nearly parallel in lateral view ( Kanmiya 1971).
