Characters of the male genitalia are combined with morphological characters of the females and nests and used in a phylogenetic analysis. The single cladogram resulting supports monophyly of the genus Pseudopolybia and interrelationships among the species as: P. langi + (P. difficilis + (P. compressa + P. vespiceps)). A new, illustrated identification key is presented.1-11engArtigo10.1206/0003-0082(2007)3586[1:PAOTNP]2.0.CO;2WOS:000249468000001Acesso restrito0000-0003-0207-1067
