摘要：
A new species, Tanychora loki, sp. nov., and a new genus and species, Megachora sibirica gen. et sp. nov., are described from the Lower Cretaceous of Transbaikalia and Mongolia. The genus Tanychora Townes, 1973 is divided into two genera: Tanychora s. str., composed of T. petiolata Townes, 1973 (type species), T. sinensis Zhang, 1991, and T. loki sp. nov., and Amplicella, gen. nov., composed of A. sessilis (Townes, 1973) (type species), A. exquisite (Zhang et Rasnitsyn, 2003), A. beipiaoensis (Zhang et Rasnitsyn, 2003), and A. spinata (Zhang et Rasnitsyn, 2003). The frequency of occurrence of ichneumonids in the principal Cretaceous localities of central and northern Asia is calculated.
