Li, Yu-Jian & Li, Zi-Zhong, 2012, A new species of the leafhopper genus Riseveinus Li, 1995 (Hemiptera: Cicadellidae: Evacanthinae) from China, Zootaxa 3185, pp. 59-63 : 60-63

Riseveinus baoshanensis sp. nov.

( Figs 1–11 )

Measurements: Body length (including tegmen): 3, 7.5–8.0 mm; Ƥ, 8.5–9.0 mm. Vertex ( Figs 1, 2 ) slightly shorter than pronotum and scutellum together.

Pygofer ( Fig. 7 ) longer than height, conically produced caudally, with some setae near end. Subgenital plate ( Figs 7, 11 ) elongate, with two rows of macrosetae. Apical process of style with equally produced mesal and lateral angles ( Figs 8–10 ). Aedeagus ( Figs 8, 9 ) with stout bilobed dorsal apodeme, shaft with paired lateral acerose processes, unpaired curved ventral process slender, shorter than shaft; shaft curved, broadened near apex and tapered to apex, gonopore apical. Other male genitalia characteristics as in Figs 7–11 .

Female slightly longer than male; vertex ( Figs 3, 4 ) slightly longer than pronotum and scutellum together; sternite VII with a median carina and distinctly extended posteriorly in midline ( Figs 6 , 12); ovipositor exceeding apex of pygofer ( Figs 6 , 12).

Type material. Holotype 3, CHINA: Yunnan Prov., Baoshan, Baihualing, 1600–1800m, 13~ 15 June 2011, coll. Zhang Bin. Paratypes: 13, same data as holotype, coll. Li Yujian; 131Ƥ, same data as holotype, coll. Yang Zaihua; 2ƤƤ, same data as holotype.

Etymology. The species name is derived from the type locality.

Remarks. Outwardly this species resembles Riseveinus asymmetricus Zhang, Zhang & Wei , but it can be distinguished from the latter by the dorsal apodeme of aedeagus bearing a pair of acerose processes and ventral processes shorter than aedeagal shaft ( Figs 8–9 ).
