title: Preliminary results of anatomical study of molluscs of the genus Helicopsis (Hygromiidae) of Crimea and Black Sea Lowland
abstract: The structure of the distal parts of the reproductive system of the majority of the species of the genus Helicopsis occuring in Crimea and Black Sea Lowland ( H. retowskii , H. dejecta , H. striata ) were studied. The special attention was given to the intraspecific variability of the penial papilla shape and some proportions of the genitalia. Basing on the anatomical characters, the wide range of the conchological variability of H. retowskii has been shown. The area of this species extends outs
