Oecleopsis wuyiensis sp. nov.

( Figs 27–36 )

Description. Length (from apex of vertex to tip of fore wings): 3 5.5-6.0 mm, Ƥ 7.0- 7.3 mm.

Face, vertex, pronotum, mesonotum, abdomen brown-black, carinae and borders yellow. Vertex 2.6 times as long as broad, subapical carina V-shaped ( Figs 34, 35 ), outer sides of vertex black with a yellow spot ( Fig. 36 ). Frons black, postclypeus dark brown. Tegmina 3.0 times as long as broad, veins yellowish with concolorous granules; stigma yellow to brown. RA unbranched, RP apically trifurcated, MA apically trifurcated, MP apically bifurcated, CuA bifurcated; Sc+R forked at same level as fork CuA1+CuA2; apex with eleven cells ( Fig. 27 ). 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. Genital styles symmetrical, T-shaped in ventral view ( Fig. 28 ). Aedeagus in total with four spines. Apical process of flagellum bifurcated, rami of bifurcation asymmetrical, right ramus longer and thicker, left ramus slender and shorter, the length of right ramus about 1.8 times as long as that of left ramus, thickness of right ramus two times as thick as that of left ramus ( Figs 32, 33 ). Two subapical spines, dorsal one longer and tapering to apex, curved dorsocephalad; ventral one awl-shaped, curved left-ventrocephalad. Spine on right side of periandrium at apex of aedeagus shorter ( Fig. 31 ).

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

Etymology. Named after Wuyi, the type locality.

Distribution. China (Fujian, Shaanxi, Henan, Hunan).

Remarks. This species is very externally similar to O. sinicus but can be distinguished from the latter by the following characters: 1) the apical process of the flagellum bifurcated, the rami of bifurcation asymmetrical, right ramus longer and thicker, left ramus slender and shorter, right ramus 1.8 times as long as length of left ramus; 2) the dorsal subapical spine of the flagellum is longer and tapering to apex, curved dorsocephalad; the ventral one awl-shaped, curved left-ventrocephalad.
