Data on the larval shells (glochidia) morphology of the anodontin genus Colletopterum (Bivalvia: Unionidae: Anodontinae) from European part of Russia, Siberia and Transbaikalia are given. All morphometric characters of the analysed glochidial shells are homogenous between investigated water basins, as well as between species of the genus. Microsculpture of the outer surface of glochidial shells has the same features for all studied localities and can be described as loop-like structures forming distinct rows that extend in the dorso-ventral direction and cover the entire surface of the valves.
