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 : 45-46

Typhlocyba napoensis sp. nov.

Figs 1–11 .

Description. Color pattern of dorsum as in Figs 1–2 . Patches on pronotum and scutellum and irregularly sinuated band on forewing, reddish-orange; basal triangles of scutellum surrounded by red streaks; small spot on base of 3rd apical cell blackish brown. Abdomen ivory.

Abdominal apodemes reaching to end of 5th abdominal sternite.

Male genitalia: Pygofer side tapering, with short finger-like protrusion at upper angle of posterior margin, with few setae beneath ( Figs 4–5 ). Subgenital plate slender gradually narrowing caudad and knob-like terminally ( Fig. 6 ); several short setae apically and subapically ( Fig. 7 ). Paramere slim ( Fig. 8 ). Connective nearly M –shaped ( Fig. 9 ). Aedeagal shaft arcuate, with pair of basal processes sculptured on apical 1/3, sinuate and exceeding end of shaft ( Figs 10–11 ).

Measurement: Male, 2.94 mm (including wings).

Type material. Holotype: ɗ, CHINA. Guangxi Province: Napo, Defu , 19.vi.2000, coll. Chaodong Zhu; paratype, 1ɗ, 19.vi.2000, same date as holotype, coll. Jian Yao (both IZAS).

Notes. The new species belongs to T. quercus group and resembles T. irenae Sharma (1984) in male genitalia, but can be distinguished by 1) aedeagal shaft with basal processes longer, exceeding end of shaft, while in T. irenae processes not reaching apex of shaft; 2) aedeagal shaft processes sinuate and close to shaft in posterior view, rather than straight and detached from shaft as in T. irenae ; 3) color pattern on forewing brighter and uninterrupted, while in T. irenae patches on forewing irregular and interrupted.

Etymology. The specific name is derived from the type locality, Napo.
