Abstract

The Brazilian sharpshooter Tettigonia incarnata Germar, 1821 was treated as incertae sedis in the most comprehensive and recent monograph of the New World Cicadellini. We have been able to identify male and female specimens of T. incarnata from northeastern and southeastern Brazil using high-resolution images of two syntypes deposited in the Museum für Naturkunde, Universität Humboldt, Berlin. Here we transfer T. incarnata to the genus Kogigonalia Young, 1977 and provide a detailed redescription of this species, including information on intraspecific color variation. In addition, we provide an updated key to the species of Kogigonalia. This is the first record of the genus from Brazil. Kogigonalia incarnata comb. n. can be recognized, among other features, by the subgenital plates with a distinct emargination at outer margin, aedeagus with a ventral unpaired process near midlength of shaft, and female sternite VII bearing an elongate strong projection on posterior margin.
