Nemésio, André & Ferrari, Rafael R., 2011, Species of Euglossa (Glossura) and E. (Glossuropoda) (Hymenoptera: Apidae: Euglossina) occurring in the Amazon, including new records for Brazil, Zootaxa 2885, pp. 1-13 : 5-8

Diversity of Euglossa (Glossura)

Twenty-three species are now known in Euglossa (Glossura) and E. (Glossuropoda), four of them endemic in the Atlantic Forest ( Euglossa cyanochlora Moure, 1996 , Euglossa iopoecila Dressler, 1982a , Euglossa roubiki Nemésio, 2009 , and Euglossa stellfeldi Moure, 1947 sensu Nemésio 2009a ) and three of them endemic in Central America ( Euglossa asarophora Moure, 1969 , Euglossa flammea Moure, 1969 , and Euglossa nigrosignata Moure, 1969 ). The remaining sixteen species occur in northern South America, one of them ( Euglossa natesi Parra-H, Ospina- Torres & Ramírez, 2006) only recorded from the westernmost part of the continent, west to the Andes in the Chocó region of Colombia and Ecuador ( Parra-H et al. 2006: 34), thus not reaching the Amazon Forest and not treated here; two of them ( Euglossa rufipes Rasmussen & Skov, 2006 and Euglossa tiputini Roubik, 2004 ) occurring at the westernmost part of the Amazon Basin; one ( Euglossa inflata Roubik, 2004 ) only recorded from the Guianas; and twelve species have a more widespread distribution, all of them known from the Brazilian Amazon, one of the most diverse assemblages of Euglossa (Glossura) (see Table 1 ). Three of these species were only recorded in the Brazilian Amazon recently: Euglossa allosticta Moure, 1969 , formerly known only from Central America ( Roubik & Hanson 2004), was first recorded in Brazil by Nemésio & Morato (2004, 2006a, b), for the state of Acre, and subsequently was found in Roraima ( Nemésio 2005b) and Amazonas ( Dias 2007). The other two records, E. lugubris and E. occidentalis , are introduced in this study and discussed below.

Another species which deserves further attention is E. orellana Roubik, 2004 . This species was only recently described, but it is very common throughout the Amazon Basin and there has been some confusion between it and E. chalybeata Friese, 1925 . Specimens collected in the state of Amazonas and identified as E. chalybeata by Powell & Powell (1987), Becker et al. (1991), Morato et al. (1992), Morato (1994), and Oliveira & Campos (1995, 1996) may belong to this species. Nevertheless, subsequent studies confirmed that both species are sympatric in the state of Amazonas (e.g. Dias 2007), as well as in the state of Roraima (e.g. Oliveira et al. 2010) (see Table 1 ).
