Abstract The taxonomy of Dinelytron Gray (Prisopodidae: Prisopodinae) is controversially discussed in the literature, as well as the delimitation between Prisopodini genera. The phylogenetic relationships between Prisopodini genera were never studied. Attempting to resolve these problems, Dinelytron was reviewed and a phylogeny was conducted to test the monophyly of the genus and better delimitate the limits of the tribe genera. Resulting, Prisopoides gen. nov., with four species was described. In Dinelytron, one species is redescribed and five new Brazilian species are described. Dinelytron unilineatus (Redtenbacher) comb. nov. was transferred from Damasippus Stal. New diagnosis for Damasippus and Prisopus are proposed, based on external characters and of the male genitalia. The phylogeny recovered two most parsimonious trees, both supporting the taxonomic changes proposed in the present study. Prisopodini and each of its genera are shown to be monophyletic. Novelties on the male genitalia are described and discussed, as well as their impact over Phasmatodea systematics.
