Geographical records. Brazil, Espírito Santo; Rio de Janeiro: Itatiaia. Remarks. As the type species of Dinelytron, this species is fundamental to the revision of the genus, as it provides a baseline for comparisons with other intrageneric species and serves as a reference for the differentiation of Dinelytron with other genera of Prisopodini. Westwood (1859) confirmed that the type specimen was lost, as it was included in the part of the entomological collection of the Museum of the Zoological Society which was sold. The specimens were identified as Di. grylloides based on Redtenbacher (1906) description of the subgenital plate - " Lamina subgenitalis _ apice profunde incisa ", which can be translated freely as "male subgenital plate with deep incision at apex". This is consistent with the subgenital plate observed in the designated specimens. Moreover, Redtenbacher identified the ZMUH specimen as Di. grylloides.
