Abstract
Species of Mimapsilopa from Brazil are reviewed with an emphasis on the fauna from southern Brazil, where six new species were discovered and herein are diagnosed and described. To facilitate identification of species, we have included a diagnosis of the tribe Discomyzini and of Mimapsilopa and have also provided an annotated key to the New World genera of the tribe. We have also provided photos of representative specimens, illustrations of structures of the male terminalia and a distribution map for all included species.
