Abstract

Ichneumonid wasps, also known as Darwin wasps, are relatively rare in Cretaceous amber deposits, with only the highest diversity documented from mid-Cretaceous Kachin amber. In order to enhance our understanding of the past diversity of this group, we describe and illustrate a new species belonging to the genus Rasnichneumon Kopylov et al., 2021, named Rasnichneumon nevergo sp. nov. This newly discovered species is based on an exquisitely preserved specimen and can be readily distinguished from the congeners by its forewing, with 2-Rs slightly longer than 2+3-M. With the addition of this new species, the diversity of the genus Rasnichneumon now encompasses five species, and we anticipate the description of more species in the future.
