Gastropod Aporrhais pespelicani was recently recorded for the first time in several localities along the Murman Coast (SW Barents Sea). In all areas, only single specimens were collected with the exception of Kislaya Inlet where the dense population was found. We repeated field study in the Kislaya Inlet decade later after the first findings of the species. No living specimens were found at the place of the previous habitat of the population of Aporrhais pespelicani, however, two adult snails were collected in a remoted locality from the same waterbody. We hypothesize that distribution of Aporrhais pespelicani in the its northern edge of range fit to “core-satellite” metapopulation model, where Murman local populations representing “satellites” of the Norwegian “core”. There is no evident proof on the relation of recent records of Aporrhais pespelicani with range extension due to the climate change, as it was suggested before.

A relict and endemic species of the Blue Nile drainage basin, the mussel Unio abyssinicus, is under the threat of extinction, with the continuing decline in the area, while data on the localities and biology of the mollusc are scarce. A new find of the mollusc population in the Duko river, located in the Oromiya Region of south-western Ethiopia, gives additional information about distribution of this species. The morphology of siphons of U. abyssinicus has been studied for the first time, the features of siphonal papillas are compared with those of the other mussel species. The data on the beak sculpture as well as the morphology of the hinge teeth have been clarified. Some new data on biology of the mussel are provided.

Description of Neofruticicola donum gen. et sp. nov. from Kugitangtau Range (Central Asia) has presented. Conchologically the new species is similar to Fruticicola perlucens (Rosen, 1901), but anatomically it represents an unique for Bradybaenidae case of partial reduction of accessory organs of female part of the reproductive tract.
