Preliminary data on the geographical distribution of Drosophila species within morphoclimatic domains of Brazil. III. The cardini group

Abstract

A reanalysis, based on museum specimens, of our previously published data on the geographical distribution of the species of Drosophila belonging to the cardini group in Brazil is presented and discussed. As previously recorded in several papers, including ours, the following four species were recognized: D. cardini, D. cardinoides, D. neocardini, and D. polymorpha. However, it was realized that most of the flies we have previously identified as Drosophila cardinoides belong in fact to Drosophila cardini. To facilitate the proper identification of these four near-sibling species, their holotypes were analyzed and their terminalia were described and illustrated. A key to the four species is also provided.
