Description. Length (from apex of vertex to tip of fore wings): 3 5.8–6.8 mm, Ƥ 6.4–7.1 mm.
Frons, vertex, pronotum, mesonotum and abdomen black, carinae and borders yellowish. Vertex about 1.7–2.1 times as long as broad, subapical carina V-shaped; outer sides of vertex black with a yellow spot; frons black, postclypeus yellowish brown and thus face two-coloured but with a small contrast. Tegmina 3.3 times as long as broad, veins yellowish with brown granules; stigma dark brown; RA unbranched, RP apically trifurcated, MA apically trifurcated or bifurcated, MP apically bifurcated, CuA bifurcated; Sc+R forked at same level as fork CuA1+CuA2; apex with ten or eleven cells (Fig. 1). Legs with femora brown, tibiae and tarsi yellowish. Chaetotaxy of hind tarsomere 7/5.
Male genitalia (Figs 2–6). Ventromedian process in ventral view generally triangular in outline, short, stout, broadest at base, slightly constricted in the middle, its apex bluntly pointed (Fig. 2). Genital styles symmetrical. Aedeagus in total with four spines. Apical process of flagellum bifurcated, rami of bifurcation symmetrical, almost equal in length (Fig. 6). Two subapical processes, short, dorsal one larger, tapering to end, directed left-cephalad; ventral one smaller, arising from base of apical process, basal portion directed left-cephalad, apex curved ventrad. Spine on right side of periandrium at apex of aedeagus shorter (Figs 4, 5).
Female genitalia. Caudal border of pregenital sternite shallowly excavated in middle, with two small convex processes submedially. Anal segment rectangular.
Material examined. CHINA: 2 Ƥ, Hunan, Chenzhou, 16-VIII-1985 (Y. L. Zhang) (NWAFU); 2 3, Fujian, Fuzhou, Xihu, 12-V-1964 (Z. C. Zhang) (NWAFU); 2 3, Guangxi, Lingchuan, Lingtian, 5-VI-1984 (Z. L. Wu & X. L. Lu) (NWAFU); 2 3, Hunan, Hupingshan Mountain Nature Reserve, Quanping Village, 20- VII-2006 (H. W. Guo) (NWAFU).
Distribution. China (Hunan, Guangxi, Fujian), Japan.
Remarks. Oecleopsis sinicus closely resembles O. bifidus, O. mori, O. artemisiae and O. wuyiensis sp. nov. in the presence of a bifurcate apex of the flagellum. It differs from O. bifidus in the presence of two subapical spines instead of one on the flagellum, from O. mori in the insertion of the apical spine on the right side of the periandrium which is inserted closer to the apex of the aedeagus in O. sinicus, and in the rami of bifurcation which are extremely asymmetrical in O. mori, from O. artemisiae in the apical spine on the right side of the periandrium which is much longer in O. artemisiae, and from O. wuyiensis sp. nov. in the symmetrical rami of bifurcation (asymmetrical in O. wuyiensis sp. nov.). In O. sinicus, the dorsal subapical spine is larger, tapering to the end, directed left-cephalad, the ventral one smaller, arising from the base of the apical process, the basal portion directed left-cephalad and the apex curved ventrad.
