Guo, Hong-Wei, Wang, Ying-Lun & Feng, Ji-Nian, 2009, Taxonomic study of the genus Oecleopsis Emeljanov, 1971 (Hemiptera: Fulgoromorpha: Cixiidae: Pentastirini), with descriptions of three new species from China, Zootaxa 2172, pp. 45-58 : 54-56

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.
