A New Genus, Sordana, for the "Gypona Sordida" Complex Homoptera: Cicadellidae

Abstract

The genus Sordana is discussed and a new species S. sordelta (collected in Bolivia) is described. A key to males of S. sordida (Stal), S. placida (Spangberg) and S. sor delta n-sp. is presented. All three species are so similar in form and coloration that they could be placed in the same species except for the differences in male genital structures.
