Abstract

The leafhopper genus Cornicola Ohara & Hayashi, previously recorded from Japan, is recorded from China for the first time and a new species, C.maculatus Xu, Dietrich & Qin, sp. nov., is described and illustrated, including its color polymorphism. This genus has male genitalia and hind wing venation similar to those found in Empoascini but it is more appropriately placed in Dikraneurini. A key to species of Cornicola is given together with a key to the genera of Dikraneurini from China.

Keywords: Auchenorrhyncha; Homoptera; distribution; leafhopper; morphology; polymorphism; taxonomy.
