Abstract

A new species of Trypoxylon is described from females and males collected in trap-nests and Malaise traps disposed in sites of Atlantic forest in southern Brazil (Paraná and São Paulo states). Trypoxylon basirufum sp. nov. is structurally very similar to Pisoxylon roosevelti Antropov, differing in details of the color pattern, clypeal apex, male antenna and propleura. In an ongoing molecular phylogenetic study of the genus Trypoxylon, T. basirufum sp. nov. did not group with Pisoxylon amenkei Antropov, a species very close morphologically to P. xanthosoma Menke, the type species of Pisoxylon. Based on these results, the scope of the Neotropical wasp genus Pisoxylon Menke is changed to include only the type species and P. amenkei, and consequently Pisoxylon roosevelti is transferred to Trypoxylon s. str.
