Rhaphium beringiense was described only after males collected from the Russian Far East and Alaska (Negrobov 1979). Males and females of this species were collected on the Taimyr Peninsula and in the Altai Mountains. Here we give the description of the female.</p><p>In the key to Palaearctic species of Rhaphium (Negrobov 1979), the female of R. beringiense comes closest to R. albomaculatum (Becker, 1891), but differs by black legs and smaller size.</p><p>Distribution.
