Subfamily Cryptinae Kirby, 1837 Cryptinae is the largest subfamily of Ichneumonidae, about 3,100 species have been described, in 275 genera (Broad et al., 2018). Mostly species are external parasites of insect pupae and cocoons. The earliest Cryptinae are recorded in the Early Eocene (Green River Formation) (Spasojevic et al., 2018b). A high occurrence and species diversity were noted in the Beds of the Bembridge marls (Khalaim, 2014), Florissant (Brues, 1906, 1910), and Biamo (Khalaim, 2008). However, they are rare in the Early Eocene Tadushi Formation (Tolkanitz & Perkovsky, 2018). The subfamily dominates in inclusions of Baltic amber in terms of abundance, constituting more than 44% of the studied samples. The fossil fauna of Baltic amber is completely unrevised and not a single species has been formally described.
