Abstract
Two new species of the genus Euglossa Latreille, subgenus Glossurella Dressler are here presented. Euglossa (Glossurella) embera sp. n., from the Pacific lowlands of Colombia, and Euglossa (Glossurella) adiastola sp. n., from the Atlantic Forest of Brazil. Their taxonomic association and distinction are discussed, as well as the correct understanding of the subgenus Glossurella.
Highlights
The appealing external morphology and interesting behavioral features of orchid bees make them one of the most notorious groups among the Neotropical bee fauna
Discovery of new suites of morphological features, and access to newly collected sets of specimens in recent years has contributed to the recognition of various new species, in Euglossa (e.g., Hinojosa-Díaz and Engel 2007, 2011a, b; Hinojosa-Díaz et al 2011; Nemésio 2007, 2011b, 2011c; Parra et al 2006; Ramírez 2005, 2006; Rasmussen and Skov 2006)
The two new species described here are unequivocally related to E. bursigera Moure, E. augaspis Dressler, and E. prasina Dressler
Summary
The appealing external morphology and interesting behavioral features of orchid bees make them one of the most notorious groups among the Neotropical bee fauna. Males of this group of bees have a characteristic set of secondary sexual morphological features involved. Discovery of new suites of morphological features, and access to newly collected sets of specimens in recent years has contributed to the recognition of various new species, in Euglossa (e.g., Hinojosa-Díaz and Engel 2007, 2011a, b; Hinojosa-Díaz et al 2011; Nemésio 2007, 2011b, 2011c; Parra et al 2006; Ramírez 2005, 2006; Rasmussen and Skov 2006). We discuss the taxonomic affiliation of both species and one possible re-interpretation of the subgenus Glossurella in the light of current phylogenetic hypotheses
