Two new species of Drosophila(Diptera, Drosophilidae) associated with inflorescences of Goeppertia monophylla(Marantaceae) in the city of São Paulo, state of São Paulo, Brazil

Two new Brazilian species of Drosophila(subgenus Drosophila) are described and illustrated: Drosophila asymmetricasp. nov. and Drosophila peixotoisp. nov. Both species were collected, and emerged, from inflorescences of Goeppertia monophylla(Marantaceae) in the urban Forest Reserve of the Instituto de Biociências da Universidade de São Paulo and their types will be deposited in the Museu de Zoologia da USP. The former species, which could not be assigned to any known group, has a conspicuously asymmetric aedeagus and a narrow oviscapt valve. The latter species belongs to the guaranigroup and is closely related to D. guaru, D. ornatifronsand D. subbadia, from which it can be distinguished by the presence of just one conspicuous large black spine at inner lower tip of cercus instead of two spines.
