[Nesting of Euglossa (Euglossa) melanotricha Moure (Hymenoptera: Apidae) in the ground of cerrado].

Nests of euglossine bees are difficult to found in nature, with descriptions available for only 20% of known species. A nest of Euglossa (Euglossa) melanotricha Moure found inside a cavity in the ground at a Cerrado area in Uberlândia, Minas Gerais state, is described. Comparisons of nesting behavior and social structure with those reported for Euglossa (Euglossa) cordata (L.) and Euglossa (Euglossa) townsendi Cokerell are presented and discussed.
