First record of the leafhopper genus Yangida Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Zyginellini) from China, with description of one new species

Abstract

Zyginellini is a smaller tribe in Typhlocybinae. Species in this tribe feed on trees and shrubs, and some species harm economic crops. Examples include as Zyginella mali (Yang) and Zyginella minuta (Yang) which damage apple trees. Members in this tribe usually have bright coloration, distinct patches and spots. Most lack ocelli. Compared with other tribes of Typhlocybinae, the main diagnostic characters of Zyginellini are: vannal veins in hindwing separate apically, only one transverse vein visible and submarginal vein extended directly to vein Cu₁, forming one open cell. This tribe is related to Typhlocybini. The Zyginellini leafhopper genus Yangida was erected by Dworakowska (1994) with Yangida basnetti Dworakowska from Sikkim, as its type species. There have been no further reports on this genus. In this paper, we describe the second species, Yangida fasciata sp. nov. from China. The type specimens of the new species are deposited in the collections of the Entomological Museum, Northwest A & F University, Yangling, China.
