(Figs 5, 6, 31–45)

Epora hainanensis Chou & Wang, 1985: 36, figs 31a–e; Men et al., 2010: 248–250, figs 1–15.

Diagnosis. Body length: male 9.5 mm (n=1), female 10.0 mm (n=1).

General colour pale green to yellowish green (Figs 5, 6). Vertex with apical and lateral margins yellowish brown. Eyes brown, ocelli yellow. Pronotum, mesonotum and abdomen green. Male genital segment pale green. Forewings with veins dark green. Legs green with apices of spines on tibiae and tarsi black.

Vertex with ratio of basal width to median length 1.7: 1.0 (Figs 5, 31). Frons with ratio of median length to width at level of anterior margin 1.5: 1.0, lateral frontal margins subparallel except where convergent in apical 1/3 (Fig. 33). Pronotum wider than long medially (4.7: 1.0) (Figs 5, 31). Pronotum and mesonotum together about 2.8 times as long as vertex in midline.

Male genitalia with pygofer quadrangular with dorsolateral angle produced rectangularly (Fig. 39). Anal tube stout, latero-distal margin produced with a pair of oxhorn-shaped processes (Figs 39–41). Genital styles about 2.4 times longer than maximum width; dorsally with an ear-like process near middle and a lateral, hook-shaped, caudad directed process below the ear-like process; at dorsal side with a triangular process in middle and a conical, dorsocaudad directed process at apex (Figs 37, 38). Periandrium tubular, surrounding aedeagus in middle, with dorsal margin connected with base of anal segment, with a pair of angular processes on ventral side apically (Figs 39– 41). Aedeagus tubular, long, with six distinct processes: two of them being apical with the ventral one triangularflaky and directed caudad and the dorsal one membranously expanded at base, apparently narrowing towards apex; remaining four processes arising from apical 1/5 of aedeagus and cephalad directed in right lateral view (Figs 39– 41).

Material examined. China: 1 male, Diaoluoshan, Hainan Province, 26 May 2008, coll. Qiulei Men (NWAFU); 1 female, Jianfengling, Hainan Province, 6 Jun. 2007, coll. Lijun Cai (NWAFU).

Distribution. China (Hainan Province).

Remarks. This species is similar to E. callosa Fennah, 1978, but can be distinguished from latter by the forewings having 17–18 costal transverse veinlets and 21–22 apical cells (9 costal transverse veinlets and 17 apical cells in E. callosa) and the transverse veinlets more densely interspersed in the subapical cells (not densely interspersed in E. callosa).
