Abstract

Keywords

This paper describes and illustrates a new Calodia leafhopper species from China (Oriental Region), namely Calodia dentispina Fan, Li & Chen, sp. n. (Cicadellidae: Coelidiinae: Coelidiini) and provides a distribution map for the new species. A key to the Chinese coelidiine genera and species of Calodia is also provided. Leafhopper, morphology, taxonomy, distribution

Introduction

The Oriental leafhopper genus Calodia (Cicadellidae: Coelidiinae: Coelidiini) was erected by Nielson (1982) based on C. multipectinata as its type species from Malaysia. The genus encompasses 60 known species at present, of which 22 species are found in China (Nielson 1982, 1991, 1996; Li 1989; Zhang 1990, 1994; Li and Wang 1991; Cai and Kuoh 1993; Xu and Kuoh 1999). Recently, we discovered one new Calodia species from China, which is described, illustrated and mapped in the present paper. A key to the Chinese coelidiine genera and species of Calodia is also provided.

Material and methods

The morphological terminology adopted herein follows Nielson (1982). Photos of external morphology were obtained by Keyence VHX-1000 system. Illustrations of male genitalia were drawn using an Olympus CX41 stereomicroscope, then enhanced by Adobe Illustrator CS6. All pictures were labelled and figs composition in Adobe Photoshop CS5. The type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

Subgenital fig long, apex with short fine setae (Fig. 8). Connective Y-shaped with stem very short (Fig. 9). Style short and simple, apophysis folded at midlength, narrowed distally to rounded apex (Figs 9, 10). Aedeagal shaft asymmetrical, elongate, distally upturned and tapered to acute apex in lateral view with numerous small spines and fine teeth, with two large subapical processes arising on same side, lower process about twice length of other bifurcate apically with inner branch also bifurcate, upper process with margin serrate in lateral view; gonopore large, subapical, situated laterally (Figs 11–13).
