A new leafhopper genus Comahadina Huang and Zhang (Hemiptera: Cicadellidae: Typhlocybinae) and a key to genera of Eupteryx-complex

摘要

Leafhoppers of the Eupteryx-complex differ from other members of the tribe Typhlocybini in having the posterior branch of hind wing vein R separate from the anterior branch of M (Young 1952). The complex now includes 9 known genera of which 5 genera,Aguriahana Distant 1918, Eurhadina Haupt 1929, Eupteryx Curtis 1833, Caknesia Dworakowska 1994, Almunisna Dworakowska 1969 and Bellpenna Chiang et al 1989, have been reported from China. Here we propose a new genus Comahadina Huang and Zhang which sharesthe hind wing character with other genera in the complex, based on a new species, Comahadina angelica Huang and Zhang, here designated as the type-species. The new genus and species are described and illustrated and a key to all genera of the Eupteryx-complex is provided. In this study we follow Dworakowska (1993) for the nomenclature of wings and Zhang (1990) for methods and other terminology.
