Abstract

The results of the survey on the new species of stagnicoline snails from the extreme North of Western Siberia are presented. The species could be distinguished from each other by both conchological and anatomical features. Snails were killed and fixed in 96% ethanol in the field and later transferred to 70% ethanol for permanent preservation. The shells are reported to be turriculate-conical, solid, light-brown, and medium-sized. Whorls are strongly inflated, sometimes almost stepped, separated by deep, oblique suture. Body whorl is moderately inflated, relatively high, and its surface is covered by growth lines and weakly malleated. Spermathecal duct is very long and narrow, roughly 3 times as long as the spertmatheca. Uterus is long and narrow and its width nearly constant along the full length. Praeputium is greyish-white, cylindrical, with its width constituting approximately 0.40-0.45 of its length.
