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