New Data on Ichneumon Wasps of the Subfamily Pherhombinae (Hymenoptera, Ichneumonidae) in Baltic Amber with Descriptions of Three New Species

Аннотация

Three new fossil species of the subfamily Pherhombinae (Hymenoptera, Ichneumonidae) are described from Primorskoe deposit of Eocene Baltic amber (Kaliningrad Province, Russian Federation): Pherhombus kasparyanisp. n., Ph. kraxtepellensissp. n., and Ph. sorgenauensissp. n. An annotated list and a key to the six known species of Pherhombinae are given. The color preservation of ichneumonid inclusions in Baltic amber is discussed, the presence of syninclusions is interpreted, and reconstruction of the species biology is attempted.
