Virpazaria Gittenberger, 1969 is distributed in the Balkan Peninsula (Albania, Montenegro and Croatia) and inhabits the shallow subterranean habitat (MSS) on limestone base rock. Reviewing historical and recently collected material, two species, Virpazaria (Virpazaria) gittenbergeri Fehér & Erőss sp. nov. and Virpazaria (Virpazaria) pesici Fehér & Deli sp. nov., are introduced as new to science. The conservation status of the new species are assessed using IUCN criteria. Two taxa, Virpazaria (Virpazaria) pageti alexanderi Reischütz & Subai, 2012 and Virpazaria (Aemiliella) ripkeni pastorpueri Reischütz et al., 2011, are synonymized with their nominate subspecies. Some new distribution records, as well as geological and geomorphological data about the known locations for Virpazaria, are presented.
During systematic surveys of groundwater snails in Slovakia, Hungary and Bosnia and Hercegovina two new species of the genus Hauffenia, H. lozekiana sp. nov. from a single locality in Slovakia, and H. steffeki sp. nov. with a small range in Bosnia and Hercegovina were discovered and are here described based on shell morphology, anatomy and DNA sequence data (COI, 16S rRNA, ITS2). The discovery of H. steffeki sp. nov. extends the range of the genus considerably towards the south. Hauffenia lozekiana sp. nov. appears to be a relict surviving within the range of the today widely distributed H. kissdalmae. Based on a time tree, we developed a scenario for the origin and diversification of the genus. The ancestor probably evolved in the Miocene on the Balkans and with the gradual desiccation of the Paratethys and its remnant water bodies diversified towards the north. Karstic and in particular alluvial connectivities together with changing courses of paleo-rivers probably played an important role for dispersal. Ecological observations suggest that the phreatic rhizosphere, the delicate net of tree rootlets and their exudates, are important for the existence of these groundwater snails.
Cochlostoma revised: the subgenus Lovcenia Zallot et al., 2015
(Caenogastropoda, Cochlostomatidae)
(2018)
Five species of the subgenus Lovcenia of Cochlostoma (Cochlostomatidae) are recognized, three of which are described as new to science: C. (L.) tropojanum sp. nov., C. (L.) jakschae sp. nov. and C. (L.) lanatum sp. nov. A lectotype is designated for C. (L.) erika (A.J. Wagner, 1906). The shell and the genital tracts are described for all species and the distributional data are summarized.
Five species of the subgenus Clessiniella of Cochlostoma (Cochlostomatidae) are recognized, viz. Cochlostoma (Clessiniella) villae (Strobel, 1851), Cochlostoma (Clessiniella) tergestinum (Westerlund, 1878), Cochlostoma (Clessiniella) waldemari (A.J. Wagner, 1897), Cochlostoma (Clessiniella) anomphale Boeckel, 1939 and Cochlostoma (Clessiniella) stelucarum sp. nov. The shells and the genitalia are described and the distributional data are summarized for all the species.
The taxa of the subgenus Turritus of Cochlostoma (Cochlostomatidae) are analysed based on molecular and morphological data. The phylogenetic trees, based on ribosomal (16S) and nuclear (H3) DNA, indicate that the currently accepted taxonomy should be revised. Based on our data, there are 37 species in Turritus of which 5 are new to science: Cochlostoma (Turritus) pallgergelyi sp. nov., C. (T. ) muranyii sp. nov., C. (T. ) hallgassi sp. nov., C. (T. ) kontschani sp. nov. and C. (T. ) lacazei sp. nov. Of these, we describe the shells and the female genitalia and summarize the distributional data. Some samples (or set of samples) will remain undetermined for lack of data and these are reported in the appendix.
