Yang, Mao-Fa, 2017, Review of the Oriental leafhopper genus Parafagocyba Kuoh & Hu (Hemiptera: Cicadellidae: Typhlocybinae: Typhlocybini), with descriptions of three new species from China, Zootaxa 4318 (1), pp. 147-156 : 148

Parafagocyba membrana sp. nov.

( Figs 1–11 , 36–43 )

Description. Length of male 4.2–4.5 mm; female 4.4–4.8 mm. Crown anterior margin with pair of dark patches, eyes dark brown, adjoining area between eyes yellowish; face yellow; pronotum mottled yellowish to brownish; mesonotum yellow medially, anterolateral triangles of scutellum brown; forewing clavus brown-yellowish, veins reddish, corium medially crimson, apical 2/5 forewing infuscate; hind wing semitransparent (figs 1–5, 37).

Coronal suture indistinct and not reaching anterior margin between eyes (figs 1, 3, 6, 8).

Male 2S apodemes weakly developed, slightly divergent, extended to anterior margin of sternite IV (fig. 39).

Pygofer side with few microsetae medially (fig. 36). Subgenital plate with one macroseta near base and row of rigid setae on lateral margin, medially apical part in ventral view with few microsetae (figs 36, 40). Paramere with a row of microsetae on outer margin and small sensory pits on inner margin on middle. Connective stem short, central ridge indistinct, and anterior arms widely divergent (fig. 40). Aedeagus simple, slightly curved; genital atrium short and wide; aedeagal shaft rounded on apex and upper than apex of ventral process; ventral process with pair of membranes on subapical part in dorsal and lateral views, U-shaped between basally joint of shaft and process; gonopore subapical (figs 11, 41–43).

Type material. Holotype, ♂, Wanglang Nature Reserve , Mianyang, Sichuan Province, China, altitude 2530 m, 23 July 2016, lights trap, Coll. Bin Yan . Paratypes, 3♂♂, same data as holotype ; 1♂ 8♀♀, Wanglang Nature Reserve , Mianyang, Sichuan Province, China, altitude 2524 m, 21 July 2016, lights trap, Coll. Bin Yan and Hongping Zhan .

Etymology. The species name refers to the membranous area on the subapical section of the ventral process of the aedeagus.

Remarks. The species is very similar to P. striata sp. nov. and P. binaria Kuoh & Hu in male genitalia, but differs in its coloration, and in having the ventral process of the aedeagus slightly curved dorsad, with pair of membranes on the subapical part, without small sculptures on the apex.
