The data on biology and taxonomy of the new subspecies Bracon pallicarpus dorytomovorus Samartsev & Dokuchaev ssp. nov. are given. It was shown that in the Northern Okhotsk region, the wasps of the new subspecies are solitary univoltine parasitoids of the Dorytomus cinereus Hochhuth, ۱۸۵۱ (Coleoptera, Curculionidae) larvae which feed on the central axis of the catkins of the willow Salix rorida Lakschevitz (Salicaceae). Having consumed the weevil larva, the parasitoid forms a cocoon inside the host's tunnel and overwinters as a pupa inside the fallen catkin. Bracon pallicarpus dorytomovorus ssp. nov. adults emerge the next year in the second half of May. The status of the specimens of the type series of B. pallicarpus pallicarpus Thomson, ۱۸۹۲ was specified and its differences from ۳۰ closely related species are presented. Bracon schmiedeknechti Fahringer, ۱۹۲۷ was synonymised with B. pallicarpus pallicarpus (syn. nov.).
