RA unbranched, RP apically trifid, MA apically trifid, MP apically bifid, CuA bifurcated; Sc+R forked distad of fork CuA1+CuA2; apex with eleven cells. Legs with femora brown, tibiae and tarsi yellowish. Chaetotaxy of hind tarsomere 7/5.

Male genitalia. Genital styles symmetrical. Aedeagus in total with four spines. Apical process of flagellum bifurcated, rami of bifurcation slender and longer, acuminate, right ramus curved upwards; two subapical spines, left subapical spine longer and stronger, directed cephalad, apex curved downwards, right one smaller, tapering, directed caudad. Spine on right side of periandrium at apex of aedeagus very long, sinuate, about 2/3 length of periandrium

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

Material examined. CHINA: 1 Ƥ, Sichuan, Ya’an, Zhougong Mountain, 13-VII-1939 (I. Chou, F. Y. Zheng & T. H. Hao) ( NWAFU); 1 Ƥ, Hainan, Yinggeling, 23-V-2007 (Y. L. Wang & Q. Zhai) ( NWAFU); 1 Ƥ, Yunnan, Longling County, Shanzipo, 5-VI-1979 (collector unknown) ( NWAFU); 1 3, Yunnan, Mengla County, Menglun Town, 9-VI-1986 (collector unknown) ( NWAFU)..

Distribution. China (Sichuan, Yunnan, Hainan), Cambodia.

Remarks. Oecleopsis petasatus can distinguished from its related species by the shape of the aedeagus, more particularly the proportions of the spines, the bifurcated apical process of the flagellum, the acuminate, slender and longer rami of bifurcation, with the right ramus curved dorsad. The spine situated at the apex of the right side of the aedeagus is very long, sinuate and about 2/3 of the length of the periandrium.

This species is recorded here for the first time from China.
