COMPAGNUCCI, Luis A  and  ROIG ALSINA, Arturo. A new species of Brachyglossula Hedicke with a remarkable morphology of the first metasomal tergum (Hymenoptera, Colletidae). Rev. Mus. Argent. Cienc. Nat. [online]. 2012, vol.14, n.2, pp.357-362. ISSN 1853-0400.

: A new species, Braehyglossula sehlumpbergeri, is described, based on two males collected in the Department of Cochabamba, Bolivia. This species is remarkable because of the structure of the first metasomal tergum, which bears a keeled projection, not present in any other bee. Its mandible is not tridentate, as it is the case in all other males of the genus. The northern distribution of B. martinezi and B. eommunis in Bolivia is extended, and floral records associated to the specimens of the treated species are provided.

Keywords : Bees; South America; Colletidae; New species.
