Phylogenetic analysis of the neotropical Pseudopolybia de saussure, 1863, with description of the male genitalia of pseudopolybia vespiceps (Hymenoptera: Vespidae, Epiponini)

The male genitalia of Pseudopolybia vespiceps are described and compared to congeners. 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. Copyright © American Museum of Natural History 2007.
