Abstract. The calanoid copepod species Diaptomus zografi Korchagin, 1887 is recorded from the East European Plain (Middle Volga Region, Russia) for the first time since the year 1925. A brief redescription and illustrations of the species are provided, and some precise details in its morphology are revealed. The studied population of D. zografi from the Middle Volga region is similar in morphological characters to populations from the environs of Moscow and Kostroma.
