First record of the leafhopper genus Varicopsella(Hemiptera: Cicadellidae: Macropsinae) in China with descriptions of a new subgenus and new species a checklist and a key to species

摘要

A new monobasic leafhopper subgenus, Varicopsella ( Multispinulosa ) Li, Dai, and Li, subgen. nov., of the subfamily Macropsinae (Hemiptera: Auchenorrhyncha: Membracoidea: Cicadellidae) is proposed to accommodate Varicopsella ( Multispinulosa ) hamiltoni Li, Dai, and Li, sp. nov.from Guangxi province of China. The new subgenus and new species are described and illustrated. They can be distinguished mainly by characteristics of the fore wings with two anteapical cells; weak dorsoventrally flattened body; aedeagal shaft with paired apical processes on ventral margin; and the shape of the dorsal connective. An updated checklist and an illustrated key for identification of the species of Varicopsella along with geographical distributions of the species are given.
