Material. Russia : 33, 2 ♀, Transbaikalia Region, “Pad’ Kapshil”, 6.VI.1943 , V.B. Dubinin [ZMU]. Remarks. The material examined shows individual variability in both males and females of the species.

Nevertheless, the pointed drawn-out apex of postpedicel distinguishes D. acutangulus from other members of the species group. Distribution. Type locality: “ Mongolia : Zentral aimak, 20 km S Ulan-Bator”. Dolichopus acutangulus was known from the environs of Ulan-Bator ( Mongolia ). Now the species is also known from Russia (southern Transbaikalia Territory).
