Type material of South American Pimpla Fabricius, 1804 (Hymenoptera, Ichneumonidae) housed in the Instituto Fundación Miguel Lillo, Argentina

In this study, we conducted a taxonomic examination of type specimens of South American Pimpla (Ichneumonidae) described by Charles Porter and deposited in the entomological collection of the Instituto Fundación Miguel Lillo (IFML), Argentina. This study aims to facilitate the morphological understanding of South American Pimpla species through the application of modern imaging techniques. A total of 11 species were examined: P. aeola, P. alnorum, P. golbachi, P. jakulicai, P. oropha, P. pyramis, P. ramirezi, P. sparsa, P. stangei, P. tafiae, and P. tarapacae.

For all species, except P. golbachi, diagnoses distinguishing Porter’s species from other Neotropical species of Pimpla, together with digital images, are presented for the first time. In addition, a taxonomic key to females of the Argentine species of Pimpla is provided.
