A New Species of the Genus <i>Crusopimpla</i> Kopylov et al., 2018 (Hymenoptera, Ichneumonidae, Pimplinae) from the Upper Eocene Baltic Amber

Abstract

A new species Crusopimpla klopfsteinae sp. nov. (Hymenoptera, Ichneumonidae, Pimplinae) has been described from the Upper Eocene Baltic amber. It is the first reliable finding of the Darwin wasps of subfamily Pimplinae in Baltic amber. The systematic position of the previously described species from Baltic amber Pimpla succini Giebel, 1856 as a taxon of uncertain systematic status (Ichneumonoidea incertae sedis) has been established. Additions to the diagnosis of the previously known by impression from the Tadushi Formation (early Eocene) are given. Finding of a representative of a subfamily Pimplinae confirms the point that the fauna of Baltic amber is an extremely selective oryctocenosis that only approximately reflects the true biological situation. It has been shown that the connections of this fauna with other fossil localities are broader than previously assumed.
