Between 2001 and 2004, 623 samples of freshwater molluscs were gathered in Hamburg and examined. In this way about 2207 sets of data indicating the presence of the genus Sphaerium, Musculium and Pisidium were found which have been ecostatistically evaluated by applying different criteria. A method of mathematically evaluation of the degree of endangerment of the Sphaeriidae in Hamburg is presented. 9 pp., 2 figs, gr. 8.…

Using published records and original data from recent field work and revision of Iranian material of certain species deposited in the collections of the Natural History Museum Basel, the Zoological Museum Berlin, and Natural History Museum Vienna, a checklist of the freshwater gastropod fauna of Iran was compiled. This checklist contains 73 species from 34 genera and 14 families of freshwater snails; 27 of these species (37%) are endemic to Iran. Two new genera, Kaskakia and Sarkhia, and eight species, i.e., Bithynia forcarti, Bithynia starmuehlneri, Bithynia mazandaranensis, Pseudamnicola georgievi, Kaskakia khorrasanensis, Sarkhia sarabensis, Valvata nowsharensis and Acroloxus pseudolacustris are described as new to science; Ecrobia grimmi (Clessin & Dybowski, 1888), Heleobia dalmatica (Radoman, 1974) and Hippeutis complanatus (Linnaeus, 1758) are reported for the first time from Iran. Additional field work is highly desirable for a more appropriate evaluation of the extant freshwater snail biodiversity in Iran. New taxa: Kaskakia n. gen., Sarkhia n. gen., Bithynia forcarti n. sp., Bithynia starmuehlneri n. sp., Bithynia mazandaranensis n. sp., Pseudamnicola georgievi n. sp., Kaskakia khorrasanensis n. sp., Sarkhia sarabensis n. sp., Valvata nowsharensis n. sp., Acroloxus pseudolacustris n. sp. 51 pp., 20 figs, br. gr. 8.…

Dieses Werk erm?glich die Bestimmung der 74 S??wasserschnecken- und 44 Muschelarten, die bisher f?r Deutschland nachgewiesen wurden. Auch das Arteninventar der meisten Nachbarl?nder ist hiermit gr??tenteils abgedeckt. Wo es f?r die Bestimmung unerl??lich ist, wird auf anatomische Merkmale des Weichk?rpers eingegangen. In kurzen Artportraits und auf ?ber 130 Fabfotos werden die wichtigsten Erkennungsmerkmale und kurz ?kologie und Verbreitung dargestellt. Neben diesem speziellen Teil findet sich auch eine Einf?hrung in die Malakologie f?r Einsteiger und zur Auffrischung f?r Fortgeschrittene. G?ttingen.

During a field trip to the western part of the Balkan Peninsula in 2016, investigations of several caves and karstic springs revealed six new gastropod species living in subterranean waters and resulted in some noteworthy faunistic records. Five of the new species are assigned to the genus Paladilhiopsis Pavlovi_, 1913, namely P. prekalensis sp. n., P. lozeki sp. n., P. szekeresi sp. n., P. wohlberedti sp. n., P. falniowskii sp. n. and one to the genus Plagigeyeria Tomlin, 1930, namely P. steffeki sp. n. New Albania and Kosovo distribution records are given for Iglica illyrica Sch?tt, 1975, Plagigeyeria zetaprotogona Sch?tt, 1960, Vinodolia matjasici (Bole, 1961), and the first georeferenced record is given for Saxurinator schlickumi Sch?tt, 1960. The most important environmental factors influencing habitat selection of these subterranean freshwater gastropods are briefly discussed. 23 pp., 34 figs, gr. 8.…
