Zethus (Zethus) wileyi (Hymenoptera, Vespidae, Eumeninae), a new species with its own species-group

Abstract

Zethus wileyi Stange sp. nov. (Panama) is described and a cladistic analysis is carried in order to determine the relationship between the new species and the other species in the hilarianus species-group. The new species is assigned to its own new species-group due to evident differences in the morphology.
