Freshwater molluscs fauna of Western Ukraine and its representation in museum collections of Lviv
Based on the literary and personal data, as well as collections of the State Museum of Natural
History of the NAS of Ukraine and the Zoological Museum of the Ivan Franko National University of
Lviv, the taxonomic composition and peculiarities of the spatial distribution of gastropods and bivalve
molluscs in Western Ukraine have been analyzed. Species lists have been drawn up for the Volhynian
(Western) Polissia, Volhynian Upland, Male Polissia, Roztochya and Opillya, Western Podillia,
Central (Northern) Podillia, Prut-Dnister interfluve, Ciscarpathian, Transcarpathian lowland and
mountainous part of the Ukrainian Carpathians. It is established that in the west of Ukraine, 74
autochthonous and 6 adventitious freshwater molluscs with generally recognized species status,
belonging to 35 genera and 15 families, can be considered as reliably registered. Adventitious to
Western Ukraine are Potamopyrgus antipodarum, Physella acuta, Menetus dilatatus, Dreissena
polymorpha, D. bugensis, Sinanodonta woodiana. Additional confirmation requires the presence of
Lithoglyphus pyramidatus, Omphiscola glabra, Physella heterostropha, Planorbis carinatus, Pisidium
conventus and P. tenuilineatum.
Not taking into account the Central Podillia, poorly researched by malacologists, a distinctly
pronounced decrease in the species richness of freshwater molluscs is observed only in the mountainous
part of the Ukrainian Carpathians (38 species, 17 genera, 8 families), with the presence of some specific
components of freshwater molluscs complexes (small gastropods of the genera Bythinella і
Paladilhiopsis). The richest taxonomic composition of freshwater molluscs was noted for Volhynian
Polissia: 67 species, 29 genera, 15 families. It has been found that most freshwater molluscs are evenly
distributed throughout the plain and foothill territories of Western Ukraine. Only few species can be
considered as specific components of freshwater malacocomplexes for one of the physical-geographical
areas or river basins. A number of species that are not present in the malacological collection of SMNH
NASU, as well as the territories poorly represented in it, have been identified. The results obtained will
be taken into account when further collecting the museum collection.
