Description. Length (from apex of vertex to tip of fore wings): 3 5.1–5.7 mm, Ƥ 6.4–6.8 mm.

Head and pronotum black, carinae and borders yellowish; mesonotum totally black, carinae black; abdomen black. Vertex about 1.6–1.7 times as long as broad, subapical carina V-shaped. Tegmina 3.1 times as long as broad, slightly yellowish; all veins and stigma yellowish. Veins covered with concolorous granules; RA unbranched, RP apically trifurcated, MA apically trifurcated, MP apically bifurcated, CuA bifurcated; Sc+R forked at same level as fork CuA1+CuA2, apex with eleven cells. Legs with femora dark brown, tibiae and tarsi yellowish. Chaetotaxy of hind tarsomere 7/5.

Male genitalia. Ventromedian process in ventral view generally triangular in outline, short, stout, broadest at base, its apex tapering and bluntly pointed. Genital styles symmetrical. Aedeagus in total with five spines. Apical process of flagellum bifurcated, curving to right, rami of bifurcation extremely asymmetrical, left ramus about three times as long as length of right ramus; an awl-shaped process at midway of left lateral side of flagellum, directed dorsocephalad; another awl-shaped process at right apical angle of flagellum, directed cephalad; a small spine on ventral margin at base of flagellum before sclerified periandrium. Spine on right side at apex of aedeagus shorter.

Female genitalia. Caudal border of pregenital sternite shallowly excavated in middle, with two small convex processes submedially. Anal segment elliptic.

Material examined. CHINA: 1 3, Yunnan, Xishuangbanna, Menglun, 21/ 30-IV-1974 (I. Chou, F. Yuan & Y. Y. H u) (N WA F U); 1 3, Yunnan, Jinghong, 21-V-1974 (collector unknown) (NWAFU).

Distribution. China (Yunnan, Taiwan).

Remarks. This species is closely related to O. sinicus and O. wuyiensis sp. nov., but can be distinguished from the latter two species in the proportion and implantation of the spines on the aedeagus, especially in the rami of bifurcation with the left ramus about three times as long as the length of the right ramus.

This species is recorded here for the first time from the Chinese mainland (Yunnan Province).
