“…The absence of any substantial genetic difference between these snails means that conchological traits such as general shell shape and the relative spire height are irrelevant for species delineation and identification in this group (despite the claims of Kruglov, 2005). This may be explained as the result of intraspecific conchological plasticity, a phenomenon which is widespread among freshwater pulmonate gastropods and, in the past, created much difficulties for their classification (Kruglov, 2005; Osikowski et al., 2018; Vinarski, 2018).…”

“…It is especially true for character-poor and species-rich families such as Lymnaeidae and Hydrobiidae in Gastropoda and Unionidae and Sphaeriidae in Bivalvia. The case studies, where the DNA-based approach to classification resulted in drastic changes in accepted taxonomy of freshwater mollusks, are numerous (Aksenova et al, 2017(Aksenova et al, , 2018Bolotov et al, 2015Bolotov et al, , 2020Klishko et al, 2017;Osikowski et al, 2018, to cite a few recent examples).…”

The taxonomic position of three nominal species of lymnaeid snails placed by Kruglov & Starobogatov (1993) into the subgenus Lymnaea (Pacifimyxas) Kruglov & Starobogatov, 1985, has been reassessed based on a molecular genetic study of topotypic specimens and an examination of the type series and other materials available. It has been shown that the two species, Lymnaea (Pacifimyxas) magadanensis Kruglov & Starobogatov, 1985 and Lymnaea (Pacifimyxas) streletzkajae Kruglov & Starobogatov, 1985, are identical with the species Kamtschaticana kamtschatica (Middendorff, 1850) and must be treated as its junior synonyms. Hence, Pacifimyxas becomes a junior synonym of Kamtschaticana Kruglov & Starobogatov, 1984. The taxonomic identity of the third species of Pacifimyxas, Lymnaea (Pacifimyxas) perpolita, remains obscure, and this species is considered here as taxon inquirendum. Two other nominal species, Lymnaea aberrans (Westerlund, 1897) and Lymnaea middendorffi (W. Dybowski, 1904), have been synonymized with K. kamtschatica based on morphological and geographical evidence. The lectotype of Limnaea peregra var. middendorffi is designated. The actual level of species richness in the Beringian freshwater malacofauna may be 20-25% lower than it was determined on the basis of the traditional system. Some implications of this outcome for the biogeography of the Beringian freshwater fauna are discussed.

“…Chertoprud et al (2016) summarised the species detected during their research in the southeast Caucasus. Nevertheless, it was clear from the above works and from recent studies of the Balkan fauna (Szarowska 2006;Beran et al 2015Beran et al , 2016Rysiewska et al 2017;Grego et al 2018;Hofman et al 2018;Osikowski et al 2018;Grego et al 2019), that the Caucasian species were assigned to respective Balkan genera (Belgrandiella, Paladilhiopsis, Plagigeyeria) based only on the few morphological features of the shell, and it is not likely that they are closely related to the geographically distant morphotypes. Molecular investigations of genus Belgrandiella from Georgia (Grego et al 2017) revealed its close relationship to the genus Agrafia Szarowska & Falniowski, 2011 from Greece.…”

The position of the southwestern Caucasus as a stygobiotic Mollusca hotspot is confirmed. Molecular data of stygobiotic gastropods revealed the diversity of subfamily Sadlerianinae Szarowska, 2006, inhabiting the subterranean environment of Georgia. In addition to the well-known endemic genera Pontohoratia Vinarski, Palatov & Glöer, 2014 and Motsametia Vinarski, Palatov & Glöer, 2014, five more genera were identified in northwestern Georgia as new to the science: Kartvelobiagen. nov., Imeretiopsisgen. nov., Caucasopsisgen. nov., Caucasogeyeriagen. nov., and Hausdorfeniagen. nov. Additionally, 21 new species were found to inhabit the studied area (Samegrelo, Imereti, Racha regions in Georgia).

“…Belgrandiella from the Zrmanja River catchment area: B. krupensis from the source of the Krupa River and B. zermanica from the Zrmanja River above the Jankovića buk waterfalls. However, it has to be noted that the distinctness of these species is doubtful and both should be synonymised with B. kusceri(faLniowsKi & beran 2015, osiKowsKi et al 2018). B. kusceri was found at loc.19, 29, 41, 50-53, 56, 60, 66, 70, 71.…”

The Balkan region is inhabited by hundreds of endemic species of freshwater molluscs but the information on their distribution, as well as that on the distribution of more common and widespread species, is still insufficient; most areas have no complete inventories of their mollusc faunas. The Zrmanja is one of the largest rivers in the Adriatic part of Croatia. Its freshwater molluscs were studied in the last decade, resulting in a substantial body of distributional data. The main objective of this study was to summarise and analyse the recent distributional information on its freshwater molluscs, with special reference to endemic or threatened species. In total 33 freshwater mollusc species were found in the Zrmanja River and its tributaries at 73 sites. The middle section of the Zrmanja River and its largest tributary, the Krupa River, were the richest studied parts. Dalmatinella fluviatilis Radoman, Tanousia zrmanjae (Brusina) and Islamia zermanica Radoman, endemic to the Zrmanja catchment area, were found in the middle and lower sections of the river. Their occurrence is scattered and limited in area; T. zrmanjae is probably on the verge of extinction. The occurrence of the endemic Belgrandiella kusceri (Wagner), Hadziella sketi Bole and Kerkia sp. in springs or underground waters and an abundant population of Unio elongatulus C. Pfeiffer in the Zrmanja and Krupa Rivers is also noteworthy. The area can be regarded as an important part of the Balkan region, one of world’s hotspots of global biodiversity. Although it is protected, there are still anthropogenic factors that are negatively affecting or may affect the mollusc assemblages.
