Ichneumonoidea genera

Diachasmimorpha is a genus of the Opiinae subfamily of braconid parasitoid wasps and was first described in 1913. It is a small genus relatively restricted to the subtropics but also includes species in the Nearctic and northern Neotropical Regions. The genus is most clearly defined by an apical sinuate ovipositor, which is a synapomorphic character and defines a monophyletic lineage.

Praeichneumon is an extinct genus of ichneumon wasps from the Lower Cretaceous of Mongolia and the Russian region of Transbaikalia. It was originally described by Alexandr Pavlovich Rasnitsyn in 1983, who also added a second species in 1990. Three new species were described by D. S. Kopylov in 2012.
