Review of Scaura Schwarz, 1938 (Hymenoptera: Apidae: Meliponini).

Scaura Schwarz is a small, widely distributed Neotropical genus of stingless bees whose workers and males have the metabasitarsus as broad as or wider than the metatibia. The genus currently includes four valid species. A species complex composed of three additional species are described here as new (S. amazonica sp. n., S. aspera sp. n. and S. cearensis sp. n.). In addition to the descriptions and redescriptions of the species of Scaura, an illustrated identification key is presented, as well as updated geographical records.

The real taxonomic identity of Trigona latitarsis Friese, 1900, with notes on type specimens (Hymenoptera, Apidae).

The taxonomic history of Trigona latitarsis Friese, 1900 and its clarification based on the observation of the types and literature data are treated in this study. The paper discusses the validity of the previously proposed lectotype, deposited in the ZMB (Berlin, Germany). Based on the type series deposited in HNHM (Budapest, Hungary) as well as the original description, a new lectotype and 15 paralectotypes from Amazon forest (São Paulo de Olivença, Amazonas) are designated. Data on the geographic distribution of Scaura latitarsis (Friese, 1900) are provided.
