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.

A short overview of subterranean Balkan hydrobid genera, with special focus on genus Bythiospeum Bourguignat, 1892 and Iglica A.J. Wagner, 1928 is given. In addition, based on recently collected material in Montenegro (Vitoja Spring) and Albania (Krumë), five new species are described, namely: Bracenica vitojaensis n. sp., Islamia montenegrina n. sp., Lanzaia pesici n. sp., Bythiospeum szarowskae n. sp. and Pseudamnicola krumensis n. sp. The holotypes and paratypes are depicted. In addition a re-description of Bythiospeum gittenbergeri (A. & P.L. Reischütz, 2008) is given and the types of the Iglica spp. deposited in the NHMW are depicted, some of them for the first time.
Subterranean Biology
The stygobiotic genus Travunijana Grego & Glöer, 2019 is one of the typical elements of the subterranean freshwater fauna of the Trebišnjica River Basin in Bosnia and Hercegovina. The previous records of the genus suggested that its distribution was limited to the basin of the Trebišnjica River and adjacent parts of the southwestern Neretva Basin. In this paper we describe a new species, Travunijana djokovicisp. nov. from “Vriješko Vrelo” spring in Montenegro. The recent finding of a new species in the Skadar Lake basin (The Drin River system) suggests the possibility of a subterranean route between the Trebišnjica and the Drin drainages, indicating that likely the endemic subterranean fauna in both basins has a lower level of historical isolation than has been considered so far.
A new Montenegrospeum species from south Croatia (Mollusca: Gastropoda: Hydrobiidae)
Folia Malacologica
The extremely rich stygobiont malacofauna of the Balkans is still poorly studied, and the systematics is based mostly on shells whose characters are often misleading. An interesting stygobiont gastropod species was found in several springs feeding the Cetina River in the SW. part of Sinj Basin in Croatia. Its shell resembled the ones of moitessieriid genera Paladilhiopsis, Bythiospeum, or Iglica. Analyses of COI and H3 markers placed it close to the hydrobiid Montenegrospeum bogici Pešić et Glöer, 2012 from central Montenegro. It is congeneric but molecularly and morphologically distinct. The new species is described herein as Montenegrospeum sketi n. sp.

Karucia sublacustrina a new species of freshwater snails (Hydrobiidae, Gastropoda) is described based on material collected from Skadar Lake (Montenegro, Albania). The new species belongs to monotypic genus Karucia gen. n. The shell morphology and body shape of the new genus resembles Radomaniola Grossuana Radoman, 1973, from which it differs in the larger shells with relatively slim and a slightly, but clearly shouldered body whorl. The number of gastropods from Skadar Lake basin tallies now 50 species. The adjusted rate of gastropod endemicity for Skadar Lake basin is estimated to be 38%. By compiling faunal and taxonomic data we also aim to provide information of relevance as to conservation efforts.
New Taxa of Hydrobiidae (Gastropoda: Risooidea) from Bulgarian Cave and Spring Waters
Acta Zoologica Bulgarica
In this paper two new species of Grossuana Radoman 1973 were described and first information about the anatomy and morphology of the stygobite genus Devetakia Glöer & Georgiev 2011 was provided with a description of a new species, Devetakia mandrica n. sp. Anatomical studies of Bythiospeum schniebsae Georgiev 2011, collected from a new cave locality, revealed that this species belongs to a new genus, Balkanospeum n. gen.
New investigations of freshwater habi-tats in caves revealed five new species of the Ris-sooidea in Bulgaria. The new species: Belgrandiella maarensis n. sp., Pontobelgrandiella tanevi n. sp. (the second species from this genus ever known), Bythiospeum simovi n. sp., Bythiospeum kolevi n. sp., Bythiospeum stoyanovi n. sp. are described and types illustrated. A synopsis of all published data on this ecological gastropod group in the country was comp-liled and complemented by author's unpublished data to provide a catalogue of all known Bulgarian stygobi-otic and troglophilous freshwater snails with their lo-calities.
