Number: 419, Pages: 1 - 8

Two new species, Erromenus atrator sp. n. (Primorskiy Territory) and E. tereshkini sp. n. (Zabaikalskiy Territory) are described in the tribe Trypho­nini (Ichneumonidae). Both new species differ from other congeners by almost completely black body color and a very wide dorsal area at the base of the pro­podeum, formed by a fused basal area and areola, and by the distinctly raised upper edge of the antennal sockets. In the last character, in the structure of the clypeal foveae and of the ovipositor, the new species are evolutionarily close to the Holarctic species E. zonarius (Gravenhorst, 1820). A new subgroup of species zonarius in the marginatus species group is proposed. Key to black-colored species of zonarius species-subgroup of the Eastern Palaearctic and related species is given.
