The Diceroprocta delicata species complex is currently composed of D. delicata (Osborn, 1906) and D. delicata variety aurantiaca Davis, 1938. We described the species distribution, made morphological measurements of nine structural characters, analyzed the calling songs, and determined the thermal responses for each species. Our collections and analyses show that there are significant differences in the biogeography, morphology, and acoustics, which suggest a reorganization of the complex. We suggest that there are in fact two separate species and that the current variety be elevated to species rank with the name Diceroprocta aurantiaca Davis, 1938.
