Opis:
New materials of Tandonia totevi (Wiktor, 1975) from Bulgaria have enabled the authors to prepare a detailed redescription and to distinguish the species from those from southern Greece which have been confused with T. totevi for almost 30 years. From the southern Greek Islands, the Peloponnese and the island of Euboea at least three more species need to be described and discriminated from T. totevi. The spermatophores of T. totevi from Bulgaria are described here for the first time, as is an intra-integumental glandular secreting organ of unknown function. The first description of spermatozoa of T. totevi is included. The first photographs of living specimens and the first observations on the behaviour and ecology are provided.

Opis:
The morphology of shell, penis, and female reproductive organs was studied in five populations of Pseudamnicola exilis (Frauenfeld) from southern Peloponnese and Kithira Island (Greece). No interpopulation differences were found in any of the characters. Thirty eight sequences of mitochondrial cytochrome oxidase subunit I (COI) and nuclear ribosomal 18S RNA genes were analysed. In COI 19 haplotypes, high haplotypy diversity, low nucleotide diversity in each population, and restricted gene flow between populations were found. NCA indicated allopatric fragmentation for all populations, and long-distance colonisation and/or past fragmentation for populations 4 and 5. Mismatch distribution in the most polymorphic population 4 reflected a bottleneck followed by population growth. The values of K2P interpopulation distances, though relatively low, pointed to congeneric distinct species within the Rissooidea. The monophyly of Pseudamnicola/Adrioinsulana clade was confirmed. Most probably the studied populations of Pseudamnicola were part of a flock of vicariant species little differentiated in morphology and ecology, many of which must have disappeared due to human impact.

Opis:
A valvatiform hydrobiid gastropod, found in a spring at Dhiaselo, W of Sparta, N. Taigetos Mts., Peloponnese, Greece, was identified as Horatia hadei Gittenberger, 1982. Its protoconch sculpture, female reproductive organs and penis morphology are characteristic of Daphniola Radoman, 1973. Maximum likelihood phylogenetic analysis based on COI (cytochrome oxidase subunit I) fragments of mtDNA proved that the species is congeneric with D. exigua (A. Schmidt, 1856) and D. louisi Falniowski et Szarowska, 2000, and thus belongs to the genus Daphniola, and that D. hadei, D. exigua and D. louisi are species-level distinct taxa.

Opis:
In September 2003 we visited localities of rissooid snails in continental Greece, known from the literature. Nine springs (type localities included), situated in urbanized or cultivated areas, were destroyed, changed or under stress. Localities of Rissooidea in Greece need urgent protection, otherwise the snails may disappear altogether.
