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

Oecleopsis spinosus sp. nov.

( Figs 7–16 )

Description. Length (from apex of vertex to tip of fore wings): 3 6.0 mm, Ƥ 7.0– 7.1 mm.

Postclypeus yellowish brown; frons dark brown, median carina and lateral carinae yellowish; rostrum dark brown, moderately long, reaching caudal margin of hind coxae; ocelli small but distinct. Vertex black, 2.6 times as long as broad, subapical carina deeply V-shaped; median longitudinal carina rudimentary, only distinct in basal half of disc ( Fig. 16 ); outer sides of vertex brown with a white spot; genae yellow. Tegmina yellowish, semihyaline, 3.2 times as long as broad, veins yellowish with brown granules; RA unbranched, RP apically trifurcated, MA apically trifurcated, MP apically bifurcated, CuA bifurcated; Sc+R forked basad of fork CuA1+CuA2; transverse veins thickened and darkened up to dark brown, expanded apices of longitudinal veins fused together with peripheral vein; stigma yellow; apex with eleven cells ( Fig. 7 ). Abdomen dark brown, with yellow posterior margins of sternites; legs with femora 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 ( Fig. 8 ). Genital styles symmetrical, T-shaped in ventral view ( Fig. 13 ). Aedeagus in total with four spines. Apical process of flagellum not bifurcated, awl-shaped, curving right-ventrad. Two subapical processes, dorsal one expanded at base, acuminating to apex, curving leftdorsad; ventral one broadest basally, then abruptly constricted near midlength and acuminating to apex, bent left-ventrad. Spine on right side at apex of aedeagus shorter ( Figs 10–12 ).

Female genitalia. Caudal border of pregenital sternite shallowly excavated in middle, with two small convex processes submedially. Anal segment rectangular ( Fig. 15 ).

Material examined. Holotype 3, CHINA: Shaanxi, Foping Nature Reserve, 1-VIII-1991 (Y. L. Wang & H. Jiang) ( NWAFU). Paratypes. CHINA: 1 3, same data as holotype, ( NWAFU); 1 Ƥ, Shaanxi, Foping Nature Reserve, 1-VIII-1991 (Y. L. Wang & M. N. Wang) ( NWAFU).

Etymology. The Latin term ‘spinous’ means ‘acuminate as a spine’, referring to the apical process of the flagellum which is not bifurcated but spinelike.

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 apical process of the flagellum not bifurcated, awl-shaped, curving right-ventrad; 2) two subapical processes in total, the dorsal one expanded at base, acuminating to apex, curving left-dorsad; the ventral one broadest at base, then abruptly constricted near midlength and acuminating to apex, bent leftventrad; 3) the spine on the right side at the apex of the aedeagus is shorter than in O. sinicus .
