A new species and new records of the leafhopper genus Taperus Li & Wang, 1994 (Hemiptera,Cicadellidae, Evacanthinae) from China

Abstract The paper deals with the species of the Oriental leafhopper genus Taperus Li & Wang. A new species, Taperus daozhenensis sp. n., from Guizhou Province, China is described and new records for other Chinese species are given together with a key for their separation. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University (GUGC).


Introduction
The leafhopper genus Taperus was established by Li and Wang in 1994 with Taperus fasciatus Li & Wang as its type species, at same time Li and Wang described two more species, T. albivittatus and T. apicalis. Subsequently, three new species were described in the genus by Shen (1997, 1999) and Li and Wang (2001). Zhang et al. (2010) reviewed the genus and described three new species from China in addition to transferring one species from Onukia to Taperus and three species from Taperus to the genus Convexana Li. A new species from Guizhou Province, China is here described and illustrated. A key to all known species of Taperus is given and new records for other Chinese species of the genus are provided. Currently eight species are included in the genus.
The specimens used in this study are deposited in the Insititute of Entomology, Guizhou University, Guiyang, China (GUGC). Diagnosis. Taperus is similar to Onukia Matsumura, it differs from this genus in having the median longitudinal carina of vertex very weak, nearly indistinct; area between median carina and submarginal carina of vertex nearly flat rather than concave and male pygofer with rows or groups of stout spine-like macrosetae marginally.
For detailed generic description see Zhang et al. (2010). Taperus  Notice. After reexamining the holotype of this species, we found the count of spine-like processes on the apex of the aedeagus was wrong in the original description, we corrected it in above keys.
Vertex, pronotum and scutellum dark brown; pale median longitudinal band yellow, extending from apex of vertex to posterior margin of pronotum (Figs 1, 2). Face nearly pale yellow (Figs 1, 2). Forewing (Figs 1, 2) dark brown, with nearly white and transparent plaque in middle of costal area.
Male pygofer (Fig. 3) nearly triangular in lateral view, row of long macrosetae at end of dorsal and ventral margin. Apex of foot-like apical process of style very long and slender, about one third length of style (Fig. 6). Aedeagal shaft, recurved dorsally, expanded distally in lateral view, broadly rounded apically with pair of retrorse spinelike processes on dorsal margin subapically and one big spine-like process on dorsal margin near base (Figs 4, 5).
Other characteristics are as shown in  Etymology. The species is named after the locality of the type specimens, Daozhen county.
Remarks. This species resembles T. albivittatus Li & Wang, from which it is distinguished by: aedeagus with pair of subapical retrorse spine-like processes dorsally and one big spine-like process on dorsal margin near base. Apex of aedeagus of T. albivittatus has three spine-like processes on dorsal margin and four pairs of spine-like process on ventral margin.
