Epora Walker, 1857

Epora Walker, 1857: 145 . Type species: Epora subtilis Walker, 1857 , by original designation.

Diagnosis. Green to ochraceous tropiduchids. Head including eyes narrower than pronotum ( Figs 1, 3, 5 , 7 , 22 , 31 ). Vertex broader at base than long in midline, anterior margin rounded, projecting in front of eyes, disc of vertex slightly depressed with one median carina or sulcus ( Figs 1, 3, 5 , 7 , 22 , 31 ); frontal margins subparallel-sided and thickened, median carina distinctly ridged ( Figs 8 , 23 , 33 ). Pronotum with two median carinae on disc and one or two short lateral carinae at either side between eye and tegula ( Figs 7, 9 , 22, 24 , 31, 32 ). Mesonotum tricarinate, with a distinct transverse suture separating mesoscutellum, median carina straight, lateral carinae convergent anteriorly ( Figs 1, 3, 5 , 7 , 22 , 31 ). Hind tibia with 3 lateral and 6–7 apical spines, metabasitarsus with 5–8 spines apically. Forewings with costal cell bearing numerous transverse veinlets, Sc+R forked distad of middle of forewing, Cu1 forked in basal quarter, membrane with two ranks of irregular transverse veinlets forming numerous subapical and apical cells ( Figs 1, 3, 5 , 10 , 28 , 34 ). Male pygofer bilaterally symmetrical. Genital styles symmetrical, lobeshaped, separated at base, with a hook-shaped process on lateral side ( Figs 14 , 30 , 37 ). Aedeagal shaft tubular, elongate ( Figs 16 , 25 , 39 ). Periandrium well developed ( Figs 16 , 25 , 40 ).

Remarks. Epora differs from other tropiduchid genera in the tribe Eporini in the vertex with posterior margin broadly concave; the pronotum narrow, with two contiguous median carinae and the lateral areas strongly oblique; and the forewings narrow, moderately amplified at apex, surpassing apex of the abdomen, and the costal membrane with numerous oblique, transverse veins.

The species in the genus Epora was usually thought to have 2 distinct carinae on either side between eye and tegula ( Fennah 1970, 1982). However, the new species described in this paper has only one lateral carina on either side ( Fig. 24 ).

Distribution. China (Guangdong and Hainan Provinces), India, Vietnam, Sri Lanka, Philippines, Malaysia and Indonesia.
