Belgrandiella dobrostanica is a tiny, freshwater snail whose scientific name is derived from the Dobrostan Ridge of the western Rhodope Mountains in Bulgaria, where this species was first discovered (2).
Snails within the Hydrobiidae family rarely have any colouration in the shell, which is ordinarily white (4). In Belgrandiella dobrostanica, the cylindrical shell is whitish to horn-coloured with a glossy surface and consists of four to five whorls which are slightly rounded (2). The umbilicus at the centre of the shell is closed, and the mantle is white (2).
