Victrix umovii (Eversmann, 1846) (Lepidoptera: Noctuidae: Bryophilinae), found in the north and northwest of Vitebsk Region, is recorded for the fauna of Belarus for the first time. At the first locality (Braslav Lakes National Park), the species was collected using a light trap in an upland swamp in a Ledum-Sphagnum pine forest with Vaccinium uliginosum, surrounded by pine and spruce stands no more than 80 years old. In the second locality (Rossony District), one male was attracted to the light of a mercury vapor lamp in a clearing at the edge of a mossy pine forest, approximately 110 years old, adjacent to a site of bracken spruce forest, approximately 100 years old. The variability in the structure of the male genitalia is discussed: some specimens have a bifurcation at the apex of the cornutus to varying degrees; in the extreme case, the cornutus has the shape of two separate teeth.
