description: Oecleopsis tiantaiensis sp. nov.
(Figs 17–26)
Description. Length (from apex of vertex to tip of fore wings): 3 5.8–6.0 mm, Ƥ 7.0– 7.2 mm.
Face, vertex, pronotum, mesonotum, abdomen brown-black, carinae and borders yellow. Vertex 2.6 times as long as broad, subapical carina V-shaped, outer sides of vertex black with a yellowish white spot; frons black, postclypeus dark brown; genae yellow. Tegmina 3.0–3.1 times as long as broad, veins yellowish brown with brown granules; stigma yellow to brown. RA unbranched, RP apically trifurcated, MA apically trifurcated, MP apically bifurcated, Cu bifurcated; Sc+R forked at same level as fork CuA1+CuA2; transverse veins thickened and darkened up to dark brown, expanded apices of longitudinal veins fused together with peripheral vein; apex with eleven cells (Fig. 17). Legs with femora brown, tibiae and tarsi yellowish. Chaetotaxy of hind tarsomere 7/5.
Male genitalia. Ventromedian process in ventral view short, stout, broadest at base, constricted at subapex, then tapering and bluntly round at apex (Fig. 18). Genital styles symmetrical, T-shaped in ventral view (Figs 23, 24). Aedeagus with four spines in total. Apical process of flagellum bifurcated, rami of bifurcation strongly asymmetrical, left ramus rudimentary (Fig. 22). Two subapical spines, dorsal one broadest basally, then abruptly constricted near midlength and acuminating to apex, curved dorsocephalad; ventral one longer, pronglike, curved left-ventrocephalad (Figs 20, 21). Spine on right side of periandrium at apex of aedeagus shorter (Fig. 20).
Female genitalia. Caudal border of pregenital sternite shallowly excavated in middle, with two small convex processes submedially (Fig. 25). Anal segment rectangular (Fig. 26).
Material examined. Holotype 3, CHINA: Shaanxi, Hanzhong, Tiantai,?- VIII-1980 (J. H. Wei) (NWAFU); Paratypes. CHINA: 1 3, 21 Ƥ, Shaanxi, Hanzhong, Tiantai,?- VIII-1980 (J. H. Wei) (NWAFU); 1 3, 3 Ƥ, Shaanxi, Foping Nature Reserve, 2-VIII-1990 (Y. L. Wang & H. Jiang) (NWAFU).
Etymology. Named after Tiantai, the type locality.
Distribution. China (Shaanxi).
Remarks. This species is externally similar to O. sinicus, but can be distinguished from the latter by the following characters: 1) the left ramus of bifurcation of the apical process of the flagellum rudimentary; 2) the dorsal subapical process of the flagellum broadest at base, then abruptly constricted near midlength and acuminating to apex, curved dorsocephalad; the ventral one longer, prong-like, curved left-ventrocephalad; 3) the spine on the right side at the apex of the aedeagus is shorter and smaller.
