A tiny, freshwater snail, Belgrandiella bachkovensis takes its scientific name from the village, Bachkovo, to which it is endemic. Its shell is tiny and cylindrical, consisting of four to five whorls, and the central umbilicus is closed (2) (3). Snails within the Hydrobiidae family rarely have any colouration in the shell, which is usually white (4). In Belgrandiella bachkovensis the shell is light horn-coloured and has a glossy surface. The mantle of this species is colourless (2).
