ROIG ALSINA, Arturo. Two new species of Melitoma Lepeletier and Serville (Hymenoptera, Apidae, Emphorini) from South America, with modified hind legs in the males. Rev. Mus. Argent. Cienc. Nat. [online]. 2009, vol.11, n.1, pp.101-105. ISSN 1853-0400.

Two new species of Melitoma Lepeletier and Serville are described: M. fulviscopis n. sp. from Matto Grosso, Brazil, and M. torquata n. sp. from southeastern and southern Brazil, and northern Argentina. The males have a peculiar hind basitarsus, unique among emphorine bees, that suggests a close relationship of the two species. The basitarsus bears, on the inner surface, a longitudinal channel-like polished depression fringed with long hairs.
