A new eumenine wasp in the genus Pseudodynerus de Saussure (Hymenoptera, Vespidae, Eumeninae)

Abstract

Pseudodynerus garcetei new species is newly described from the Brazilian Amazonia. The color pattern of this species is remarkable, being very similar to that found in the eumenine Montezumia liliacea Gribodo and in the polistine Polybia liliacea (Fabricius). A re-evaluation of the phylogenetic relationships among species of Pseudodynerus is presented, which places P. garcetei as sister to a clade composed of P. subapicalis (Fox), P. carpenteri Hermes & Melo and P. obesus Hermes & Melo. A matrix containing data from the new species and a partial key for its recognition are also provided.
