Epora bilemisca Qin & Men, 2010

( Figs 1, 2 , 7–21 )

Epora bilemisca Qin & Men, 2010: 189 –192, figs 1–15.

Diagnosis. Body length: male 9.5 mm (n=2), female 9.8 mm (n=1).

General colour light green ( Figs 1, 2 ). Eyes brown, ocelli yellow. Pronotum, mesonotum and abdomen green. Male genital segment pale green. Legs green with apices of spines on tibiae and tarsi black.

Vertex with ratio of basal width to median length 2.2: 1.0 ( Figs 1 , 7 ). Frons with ratio of median length to width at level of anterior margin 1.5: 1.0, lateral frontal margins distinctly parallel ( Fig. 8 ). Pronotum wider than long medially (4.6: 1.0) ( Figs 1 , 7 ). Pronotum and mesonotum together about 4.0 times as long as vertex in midline.

Male pygofer quadrangular, post-dorsal angle roundly produced ( Fig. 12 ). Anal tube elongate, narrow, apex deflexed, with two slender ventral ribbon-like processes ( Figs 12, 13, 16, 17 ). Genital styles lobed, rounded apically, about 3.1 times as long as wide, dorsally with a triangular process in apical 2/5 and a hook-like process on surface, directed caudad ( Fig. 14 ). Periandrium short; dorsally connected with base of anal segment; on the dorsal surface with two broad compressed processes, inner margin concave, apices broadest, with two pairs of folded lobes subbasally ( Figs 15–17 ). Aedeagus tubular, membranous apically, triangularly expanded, with a long and narrow dorsal process apically, directed caudodorsad; aedeagal shaft nearly half as long as aedeagus, with two lateral flaky processes in ventral view: right one bifurcated and left one sharply narrowing with pointed apex ( Figs 15–17 ).

Material examined. China: 1 male (holotype), Jianfengling, Hainan Province, 26 Jun. 2008, coll. Qiulei Men ( NWAFU); 1 female (paratype), Jianfengling, Hainan Province, 21 Jul. 2009, coll. Manqiang Wang ( NWAFU); 1 male (paratype), Xiaoaoshanzhuang, Guangdong Province, 22 Aug. 2010, coll. Manqiang Wang ( NWAFU). Distribution. China (Hainan and Guangdong Provinces).

Remarks. This species is similar to E. callosa Fennah, 1978 , but differs from the latter in the vertex with ratio of basal width to median length 2.2: 1.0 (1.7: 1.0 in E. callosa ), the female pregenital sternite produced caudad in an arched lobe (produced subangulately in E. callosa ) and the female third valvulae having nine apical teeth (ten teeth in E. callosa ).
