Based on a large part of a skeleton, a new species of the genus Otschevia (O. alekseevi) from the Volgian Stage (Dorsoplanites panderi zone) of the Volga Region near Ulyanovsk is described. The diagnoses of the family Undorosauridae, the subfamilies included in the family, and the genus Otschevia are emended.
