Revisão taxonômica da vespa-de-Darwin Bathyzonus Townes, 1970 (Hymenoptera: Ichneumonidae: Cryptinae)

Abstract

Bathyzonus Townes, 1970 is a genus belonging to Cryptinae, Ichneumonidae, whose is pseudo parasitoid wasps of egg sacs of Uloboridae spiders. In this work, the two valid species Bathyzonus ruficauda and Bathyzonus interruptor are revised, with new diagnostic characters and the description of the male specimen of B. interruptor, which was unknown. Seven new species are described based on taxonomy integrative using external morphology and DNA barcoding locus (658 base pair of cytochrome oxidase mitochondrial gene; COI): Bathyzonus sp.A sp. nov., Bathyzonus sp.B sp. nov., Bathyzonus sp.C sp. nov., Bathyzonus sp.D sp. nov., Bathyzonus sp.E sp. nov., Bathyzonus sp.F sp. nov., and Bathyzonus sp.G sp. nov.. Here we enlarge de distribution of Bathyzonus to North Mexico to South Brazil, previously known only to Mexico and some morphospecies to few countries in South America and Costa Rica. The taxonomic review includes images, illustrations of the main diagnostic characters, identification key, and distribution maps for the genus and all species.
