BythinellaMoquin-Tandon, 1856 (Gastropoda: Rissooidea: Bythinellidae) in Romania: species richness in a glacial refugium
2009
Mitochondrial cytochrome oxidase I (COI) and ribosomal internal transcribed spacer 1 (ITS-1) sequences were analysed in 12 Romanian Bythinella populations. Phylogenetic relationships were inferred using maximum parsimony, maximum likelihood and Bayesian techniques. For COI, the Kimura two-parameter (K2P) distances and haplotype networks were computed. Two sympatric and four allopatric groups were distinguished. The K2P distances are similar to those for congeneric rissooids, so each of the six groups represents a species. Two are identified as Bythinella molcsanyi H. Wagner, 1941, and Bythinella dacica Grossu, 1946. The other four groups cannot be ascribed to any known Bythinella. The occur…
Presence of the genus Bythinella Moquin-Tandon, 1856 (Gastropoda, Bythinellidae) and other hydrobioids in Saône-et-Loire (Burgundy, France): taxonomi…

While listing spring-dwelling snails in the regionBourgogne Franche-Comté (eastern France), we found threelocalities with living representatives of the genus BythinellaMoquin-Tandon, 1856 in the department of Saône-et-Loire. Toour knowledge, they represent the only Bythinella -bearinglocalities currently known in this department. The sampledindividuals share several shell features with B. carinulata(Drouët, 1867), B. viridis (Poiret, 1801) and B. lanceleveiLocard, 1884. Pending a complementary genetic analysis, weidentify these specimens as Bythinella sp. Two of the threelocalities also yielded empty shells of Islamia andBythiospeum . They represent the westernmost occurrence ofthese stygob…
