Huang, Min & Zhang, Ya-Lin, 2009, Five new leafhopper species of the genus Typhlocyba Germar (Hemiptera: Cicadellidae: Typhlocybinae) from China, Zootaxa 1972, pp. 44-52 : 50-52

Typhlocyba bilaminata sp. nov.

Figs 43–52 .

Description. Color pattern of dorsum as in Fig. 43 . Patches on vertex and pronotum orange, basal triangles of scutellum reddish brown surrounded by reddish orange, end of scutellum and basal patches of forewing, reddish orange; distal end of brochosome field brownish orange with apical part infuscate. Abdomen with dorsal part brown, pygofer with upper posterior part dark brown, end of anal tube light orange.

Abdominal apodemes reaching to end of 5th abdominal sternite.

Male genitalia: Pygofer side bilobed at posterior margin, upper lobe triangular and pigmented, lower one truncate and with several rigid microsetae along posterior margin ( Figs 45–46 ). Subgenital plate broadened basally, narrowed medially, and slightly broadened again distally ( Fig. 47 ), with hook-like protrusion subapically ( Fig. 48 ). Paramere with central part robust ( Fig. 49 ). Connective robust, nearly M-shaped ( Fig. 50 ). Aedeagal shaft moderately slender and angularly curved, with pair of long parallel distal processes, bladelike, directed dorsally ( Figs 51–52 ).

Measurement: male, 3.05 mm (including wings).

Type material. Holotype: ɗ, CHINA. Yunnan Province: Sanchahe, 7.vi.1991, coll. Rungang Tian ( NWAFU); paratypes, 22ɗ, same data as holotype ( NWAFU and including 2 in BMNH).

Notes. The new species belongs to T. aptera group and is similar to T. aptera Dworakowska (1979) in male genitalia but can be distinguished from the latter by paired blade-like distal processes of aedeagal shaft.

Etymology. The specific name is a combination of the Latin prefix bi meaning two and the Latin word lamina, meaning blade which refers to blade-like aedeagal processes.
