All known species are described with an emphasis on structures of the male terminalia, which are fully illustrated. Detailed locality data and distribution maps for all species are provided. For perspective and to facilitate genus-group and species-group recognition, the tribe Discocerinini is diagnosed and a key to genera in the New World is provided.
