Distribution. China (Hainan, Yunnan).

Etymology. The specific name “ eminens ” (prominent) refers to the mesopleuron significantly elevated in dorsal view.

Comments. O. eminens sp. nov. can be distinguished from other species by having lateral surface of mesopectus significantly elevated in dorsal view ( Fig. 3h ); first median cell of forewing triangular ( Fig. 3i ); vertex crest straight, sides of head behind eyes almost parallel in full face view, frons and vertex with dense punctures ( Fig. 3b ).
