Two new species of Pirhosigma Giordani Soika (Vespidae, Eumeninae), with an updated catalog for the genus

Abstract

Two new species of eumenine wasps were described from Panama and Peru, namely Pirhosigma abregoi Garcete-Barrett & Hermes sp. nov. and P. cambrai Garcete-Barrett & Ferreira sp. nov. Lectotypes are designated for Eumenes deformata barberoi Bertoni and Eumenes superficialis mondaiensis Bertoni. Pirhosigma mearimense putumayense Giordani Soika stat. nov. is treated as a color variation of the typical P. mearimense (Zavattari). Additions to the key by Ferreira et al. (2017) are made and an updated catalog for species included in the genus is provided.
