“…Bythinella Moquin-Tandon, 1855: Falniowski et al 1998Falniowski et al , 1999Falniowski and Szarowska 2011). Also the genetic diversification of Central European obligatory subterranean Bythiospeum Bourguignat, 1882 suggests postglacial recolonization (Richling et al 2016) and thus some effective ways of dispersion/gene flow. Moreover, the distribution of the interstitial fauna might be much more continuous than already recorded, due to data deficiency.…”

Freshwater truncatelloidean gastropods include numerous minute cryptic species, displaying simple morphologies, all of which hampers their taxonomic research based on morphology. Phylogenetic relationships among all but one extant species of the genus Kerkia from five localities in Croatia and one in Slovenia were therefore analysed based on one mitochondrial (cytochrome c oxidase subunit I) and three nuclear markers (18S, 28S and H3). Kerkia kusceri (Bole, ), K. jadertina Kuščer, 1933, K. j. sinjana (Kuščer, 1933), and K. kareli Beran, Bodon et Cianfanelli, 2014, were collected from their type localities. Our analysis confirmed their distinctness, recovering two additional clades that may represent yet undescribed species from Croatia. Apart from Kerkia, Hauffenia media Bole, , H. subpiscinalis (Kuščer, 1932) and H. erythropomatia (Hauffen, 1856) from Slovenia were analysed. Their distinctness together with the rejection of the eligibility for separate genus Erythropomatiana for the latter species was proven. Interestingly, its sequence divergence exceeded all previous estimates for species‐level divergence within the Truncatelloidea, implying a species‐level separation both for the COI and for nuclear loci. High p‐distances for the COI/nuclear loci (0.128/0.027, respectively) confirmed also the uniqueness of both genera. A comparison of their COI sequences with the reference sequences of Alzoniella Giusti et Bodon, 1984, Avenionia Nicolas, 1882, Fissuria Boeters, 1981, and Agrafia Szarowska et Falniowski, 2011, has shown that Kerkia and Hauffenia are not sister clades. The most striking, however, was the apparent introgression of the ‘Hauffenia’ mtDNA type from central Slovenia (cave Babja luknja) into two Kerkia clades from central (Ljubač) and southern (Podgrađe) Croatia, that are located 210 km and 360 km away, respectively. The introduced ‘Hauffenia’ mtDNA type and the closest Hauffenia erythropomatia COI differed by 0.8%. Secondary loss of isolating mechanisms between phylogenetically distant organisms and the severe lack of information on distribution of these underground taxa were postulated as possible explanations of this interesting phenomenon.

“…Additionally, in many cases it is likely the last chance to obtain any study material in the locality due to dynamic environmental alterations and climatic changes. We are fully aware of the possible high variability in shell morphology among the localities of some stygobiont species as was demonstrated for the genus Bythiospeum, Bourguignat, 1882 (Richling et al 2017). However, the close molecular relationship among the studied Bythiospeum populations within this study can be most likely explained by relatively recent post glacial colonization and population dispersal to the ex-permafrost localities from only few refugia situated at the foot of the Northern Alps.…”

During the field trips to Bosnia & Hercegovina and Montenegro in the years 2015 - 2018 we investigated the subterranean freshwater gastropod fauna in several karst springs. Five subterranean gastropod species new to science had been recorded within the collected material. Three of the new species are assigned to the family Moitessieriidae: Paladilhiopsis cattaroensis n. sp., Paladilhiopsis matejkoi n. sp., Bosnidilhia vitojaensis n. sp. and two to the family Hydrobiidae: Plagigeyeria feheri n. sp. and Stygobium hercegnoviensis n. sp., the latter in the new genus Stygobium.

Truncatelloid gastropods are one of the most species‐rich subterranean invertebrate groups. Their current taxonomy is based on morphological characters. However, this is not a comprehensive approach and does not take into account the degree of phylogenetic divergence between stygobiont populations inhabiting hydrologically isolated but geographically close caves. We studied two Paladilhiopsis populations of a small and isolated karstic area (Mecsek Mountains, Hungary) with two hydrologically separated cave systems, investigating morphological (shell morphometrics) and genetic (COI, 16S) divergence together. The populations differed both morphologically and genetically: we found strong divergence in the relative width of the shell (best described by the variable “shell angle”) and a 6.4% divergence in COI. This provides strong support for the presence of two distinct taxa; however, it is still doubtful whether they differ at the species or the subspecies level. In one of the caves, we found representatives of both haplotypes (and phenotypes), which can be explained by secondary contact after an allopatric divergence.
