Stenotrema pilula

The shells of pygmy slitmouths are smaller than the majority of Stenotrema species, with an elevated spire and 5 or more whorls. The surface of the shell is covered by the fine, long hairs typical of species of the Stenotrema genus. The parietal tooth is long and hooked, and curves inwards into the interdenticular sinus. There is a large notch in the basal lip. The shell is commonly chestnut brown in color. Pygmy slitmouths range from in width and in height. == Ecology ==
