Revision of the Neotropical species of Pareucamptonyx Olmi (Hymenoptera, Dryinidae) with descriptions of new species

Abstract

The genus Pareucamptonyx Olmi, 1991 is endemic to the New World and comprises three described species, two from the Neotropical region and one from the Nearctic. Here is presented the first revision of species of Pareucamptonyx from the Neotropical region, including four new species described from Brazil: P. albopictus Martins sp. nov., P. kumagaiae Martins sp. nov., P. niger Martins sp. nov. and P. paranaensis Martins sp. nov. Detailed illustrations, distribution map, and key to females are provided, as well as a revised diagnosis of the genus and notes about the method of collection. Additionally, new distribution records for P. townesi (Olmi, 1984) are reported.

A review of the biology of the pincer wasps (Hymenoptera: Dryinidae)

“…About 90% of the dryinid species in the world belongs to the subfamilies Anteoninae, Aphelopinae, Bocchinae, Dryininae and Gonatopodinae (Olmi & Virla 2014). The genera Anteon Jurine, Dryinus Latreille and Gonatopus Ljungh contain more than half of the described species (Martins & Domahovski 2022;Tribull 2015). The works that gathered the taxonomic information available about the family are the world review by Olmi (1984) and its supplement (Olmi 1991).…”

“…Dryinidae (Hymenoptera: Chrysidoidea) are a widespread family, present in all zoogeographical regions, except Antarctica. They are parasitoids and predators of Hemiptera: Auchenorrhyncha, with over 1900 species (Martins & Domahovski 2022; Olmi et al 2020). Dryinidae, commonly known as pincer wasps, include species living in a wide range of habitats (from Patagonia to northern Europe beyond the Arctic Circle), from sea level to altitudes over 3000 m (Olmi 1999).…”

“…Within the Dryinidae family, 17 subfamilies (12 extant) and 53 genera have been reported using morphological characters (Martins & Domahovski 2022; Olmi et al 2020; Olmi, Onore & Guglielmino 2022). About 90% of the dryinid species in the world belongs to the subfamilies Anteoninae, Aphelopinae, Bocchinae, Dryininae and Gonatopodinae (Olmi & Virla 2014).…”
