Yu, Xiaofei & Yang, Maofa, 2014, Key to species of the leafhopper genus Membranacea Qin & Zhang (Hemiptera, Cicadellidae, Typhlocybinae, Empoascini), with a new species from China, Zootaxa 3878 (1), pp. 97-100 : 99

Membranacea distincta Yu & Yang , sp. nov.

( Figs 1–11 )

Length: male 4.1–4.2mm.

Body robust, dorsal coloration golden yellow ( Figs 1, 2 ). Crown with median black apical spot surrounded with cream stripe; coronal suture brown and margined with cream, beside with a brown spot ( Figs 1, 3 ). Eyes dark ( Figs 1, 2, 3 ). Ocellus present ( Fig. 3 ). Face elongate and convex in profile ( Fig. 2 ). Pronotum wider and longer than crown, with median cream spot at anterior margin ( Fig. 1 ). Scutellum yellow with basolateral triangles and apex black; scutoscutellar sulcus distinct, not reaching lateral margin of scutellum ( Fig. 1 ). Forewing rounded apically, apical cells less than 1/3 total length, RP and MP’ separated and originated from r cell, MP’’+CuA’ from m cell, width of c cell equal with r cell. Hindwing with CuA bifurcated. Abdomen brownish. Legs yellow except claws brownish ( Figs 1, 2 ).

Ventral male abdominal apodemes broad, reaching segment 4 ( Fig. 4 ), Pygofer with dosrsal margin strongly concave, apex with few microsetae ( Figs 5, 6 ). Subgenital plate broad, with an oblique line of 14 macrosetae and ca. 23 microsetae in 3 rows; outer margin bearing 5 moderately long and stout setae forming the basal group and after that along with ca. 25 marginal setae ( Fig. 7 ). Paramere elongate, with apical teeth and setae ( Fig. 8 ). Aedeagus arcuate in lateral view, with broad single central flange on ventral surface from midlength to apex ( Fig. 9 ), subapically with pair of lateral flanges on each side, inner flange narrower than outer one; preatrium more than half length of shaft ( Fig. 10 ). Connective with base broad, apex narrow, apical margin deeply emarginate ( Fig. 10 ). Anal tube process only visible in ventral view ( Fig. 11 ).

Etymology. The new species is named for its single central flange broad and distinct.

Material examined. Holotype, 1 ♂, Mt. Leigong, Guizhou Province, 5. July. 2005, coll. Yuehua Song. Paratypes, 1 ♂, Huaping, Guangxi Province, 18. May. 2012, coll. Hu Li; 2 ♂, Huaping, Guangxi Province, 18–19. May. 2012, coll. Zhihua Fan.

Remarks. The new species is similar to M. stenoprocessa Yu & Yang, 2013 and M. plana Qin & Zhang, 2011 , but differs from the latter in having the single central flange broad and extending from midlength to apex, the narrower flange is inside the broader one ( Figs 9, 10 ).
