Contribution to the knowledge of pincer wasps (Hymenoptera: Dryinidae): new records from South America

Abstract

Dryinidae wasps are poorly known in the regions of the Neotropics. Because it is a group considered rare in most collections, most species are obtained in sporadic collections using Malaise traps, flight intercepts, yellow pan traps and sweep nets. In this study new distribution records for 14 Dryinidae species belonging to three genera are provided: one species for Deinodryinus, nine species for Dryinus and four for Gonatopus with reports for Brazil, Costa Rica, French Guiana, Peru and Paraguay. The species D. maximus and G. stellaris are recorded for the first time from Brazil, while D. bolivianus, D. piscencens and Gonatopus willinki are recorded from Paraguay; D. chiapasensis is recorded for the first time from French Guiana and other species from different localities and different countries.
