Fig. 1. Phylogenetic tree hypothesized for 36 orchid bee (Apidae: Euglossini) species, based on cyt b partial sequences and inferred using the maximum likelihood method. Node bootstrap support values greater than 50% are shown. Species groupings, based on Cameron (2004), are presented in different colors. Eg., Euglossa; Ef., Eufriesea; Ex., Exaerete; El., Eulaema.
