The genus Elytrogona Chevrolat is redefined. Stoiba decemmaculata Blake is a junior synonym of E. bulla Boheman, and E. interjecta Boheman is a junior synonym of E. quatuordecimmaculata Latreille, new synonymies. A key to the species of Elytrogona and distributional records are provided. A cladistic analysis is presented using Stoiba swartzii Boheman, S. bruneri Blake, Basipta stolida Boheman (Basiptini) and Asteriza flavicornis Olivier (Asterizini) as outgroups. Results indicated that brachyptery preceeded wing loss. The origin and subsequent radiation of the genus were less clear given the complex geology of the Greater Antilles.
