Resumen de Two new species of Melitoma Lepeletier and Serville (Hymenoptera, Apidae, Emphorini) from South America, with modified hind legs in the males
Two new species of Melitoma Lepeletier and Serville are described: M. fulviscopis n. sp. from MattoGrosso, Brazil, and M. torquata n. sp. from southeastern and southern Brazil, and northern Argentina. Themales have a peculiar hind basitarsus, unique among emphorine bees, that suggests a close relationship of thetwo species. The basitarsus bears, on the inner surface, a longitudinal channel-like polished depression fringedwith long hairs.
