A taxonomic review of the monotypic genus Trochalonota Westwood, 1833, endemic to the Atlantic Forest in southeastern Brazil (Espírito Santo and Rio de Janeiro), is presented. Trochalonota badia (Germar, 1823) is redescribed, and its aedeagus is described and illustrated for the first time. The study further provides a diagnosis, a detailed nomenclatural history, and photographs of both syntypes and non-type material. A lectotype and paralectotypes are designated, and a distribution map is included. In addition, the genus is compared with Pixis Chevrolat, 1843, which has been considered in the literature as the most morphologically similar genus occurring in Brazil. A nomenclatural history of Pixis and remarks on its diversity and type species are also provided.
