ABSTRACT. A new species Aphidius medvedevi Davidian sp.n. is described from Altai Mountain in Western Siberia. It was reared from Brachycaudus aconiti (Mordvilko, 1928), mummies, which were collected on Aconitum lycoctonum L. New species looks like to A. pelargonii Starý et Carver, 1979, A. similis Starý et Carver, 1979 from Australia and A. subantarcticus Starý, 1985 from Falkland Islands by long and erected hairiness of antennae and legs. They are easy differ by host range and complex of the morphological features, including antennae, maxillary and labial palps, metacarpus, proportion between both of the radial abcissae and outline of ovipositor sheaths. Aphidius sussi Pennacchio et Tremblay, 1988, which is parasitoid of Delphiniobium junackianum Karsch, 1887, was only known before from Aconitum sp. New species differs from A. sussi by 15–16-segmented of antennae, maxillary and labial palps, more elongated metacarpus in relation to pterostigma, long and erected hairiness of antennae and legs.
