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, Taperus albivittatus and Taperus apicalis. Subsequently, three new species were described in the genus by (Cai and 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).

Type species.

Taperus fasciatus Li & Wang.

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).

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.

The species is named after the locality of the type specimens, Daozhen county.

Remarks.

This species resembles Taperus 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 aedeagusof Taperus albivittatus has three spine-like processes on dorsal margin and four pairs of spine-like process on ventral margin.
