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 : 46-48

Typhlocyba tubercula sp. nov.

Figs 12–22 .

Description. Color pattern of dorsum as in Figs 12–14 . Patches on vertex yellowish, thin streak on the lateral margin of vertex entending to anterior margin of face, then joining streak on anterolateral margin of face, brown; clypeus and gena dark brown. Patches on anterior and lateral part of pronotum and on basal half of forewing reddish-orange, on the pronotum centrally orange, on distal end of clavus and adjacent area of corium yellowish-orange and on distal end of brochosome field dark brown; apical part of forewing infuscate. Abdomen and genital capsule dark brown.

Vertex concave centrally, with anterior margin produced apically, longer than pronotum ( Figs 12–13 ).

Abdominal apodemes reaching to end of 5th abdominal sternite.

Male genitalia: Pygofer side with long finger-like protrusion at upper angle of posterior margin, serrated ventrally ( Fig. 16 ). Subgenital plate broad basally, abruptly narrowed at median with apex digitate and twisted laterally ( Fig. 17 ); corner of apex with a big tuberculate-like protrusion bearing numerous rigid microsetae ( Fig. 18 ). Paramere slim and with base pigmented (Figs 17,19). Connective pigmented, nearly M –shaped ( Fig. 20 ). Aedeagal shaft slim with pair of subapical upturned processes, broadened basally ( Figs 21–22 ).

Measurement: male, 3.39 mm (including wings).

Type material. Holotype: ɗ, CHINA. Yunnan Province: Sanchahe, 7.vi.1991, coll. Rungang Tian; paratype, 1ɗ, same data as holotype (both NWAFU).

Notes. The new species belongs to T. arborea group and comes close to T. equata Dworakowska (1982) in shape of aedeagus but characteristics of pygofer, paramere and connective are similar to T. quercus group. The most characteristic features of the new species are apically produced and centrally concave vertex and shape of the subgenital plate which becomes abruptly slender at mdlength and bears a big tuberculate protrusion at its apex.

Etymology. The specific name is derived from Latin word tuber, meaning protuberance, which refers to subgenital plate with a protrusion at its apex.
