Subfamily Hybrizoninae Blanchard, 1845

Hybrizoninae , a small subfamily of Ichneumonidae , is distributed over the Holarctic region and includes 16 extant species in four genera (Khalaim, 2018). Hybrizoninae are considered to be koinobiont endoparasitoids of ants ( Komatsu & Konishi, 2010; Durán & van Achterberg, 2011). Female wasps oviposit into larval ants while they are being transported outside of the nest by worker ants.

There are four extinct genera from Baltic amber: Astigmaton Kasparyan, 2001 , represented by the species A. ichneumonoides Kasparyan, 2001 ; Ghilarovites Kasparyan,1988 ,represented by G. tarsatorius Kasparyan, 1988 ; Tobiasites Kasparyan, 1988 , represented by T. striatus Kasparyan, 1988 ; and Paxylommites Kasparyan, 1988 , represented by P. reticulatus Kasparyan, 1988 and P. groehni Tolkanitz & Perkovsky, 2015 . The monotypic genus Paxylobembra Khalaim, 2014 with P. kozlovi Khalaim, 2014 was described from Bembridge marls.
