The genus Lithocharodes was described by David Sharp in 1876 for a single species, Lithocharodes fuscipennis Sharp, from the Amazon, Brazil. For over 130 years, the species has been mentioned only in catalogs. However, recent fieldwork found it in localities ranging from northern to southern Brazil. Lithocharodes fuscipennis differs from the other species of the genus mainly by the dark brown to black elytra with the apical quarter conspicuously lighter except on the elytral suture. The male genitalia of L. fuscipennis are illustrated, sexual dimorphism is described, and remarks on the genus, including a diagnosis, are presented.
