A new South American genus of Iassinae (Hemiptera: Cicadellidae) and additional morphological characters for two Neotropical species of Neobalinae and Nioniinae

Abstract

The new iassine leafhopper genus Ana gen. nov is described, based on the type species Ana doctrix sp. nov. from Argentina, and placed in the tribe Hyalojassini. The new genus is distinguished from other Neotropical Hyalojassini genera by setose forewings, submarginal vein evanescent apically and appendix narrower than first apical cell, male pygofer with a triangular expansion turned mesad on ventral margin, lacking hooks, styles bifid basally, and female sternite VII short, with posterior margin concave. The subfamilies Neobalinae and Nioniinae are recorded for the first time from Argentina. New female morphological characters of Calliscarta fasciata (Osborn) (Neobalinae) and the male terminalia of Nionia major(Osborn) (Nioniinae) are provided. An updated key to the 12 subfamilies of Cicadellidae present in Argentina is provided.
