Abstract

A new gastropod genus Alanstukella gen. nov., from the family Trochonematidae is described. The type species A. rossica (Stuckenberg, 1905), belongs to a small group of the largest Late Paleozoic representatives of the class Gastropoda. A. rossica has been shown to have pedomorphic features. Despite the extreme rarity of finds, the species has a wide geographical and stratigraphic distribution: the East European Craton, the South Urals and the Fergana Valley; Upper Pennsylvanian–Lower Permian (from the basal Kasimovian to the basal Sakmarian).
