10. Hybos oncus Yang & Yang, 1987

Hybos oncus Yang & Yang, 1987: 164 . Type locality: China: Tibet, Bomi.

Distribution. China (Tibet).

Remarks. This species was described by Yang & Yang (1987) from only a single male specimen collected in Tibet. Its female is still unknown. It is similar to H. furcatus in R4+5 and M1 parallel (Yang & Yang, 2004, fig. 342), but may be separated from the latter by the following characters: legs entirely black; first flagellomere with 2 dorsal setulae; hypandrium apically not trifurcated but distinctly narrowed with a small subapical lateral process shallowly incised apically (Yang & Yang 2004, fig. 344).
