Es werden zwei neue Arten aus Albanien beschrieben: Agardhiella extravaganta n. sp. und Agardhiella zoltanorum n. sp. Alle Arten werden durch Fotos und Zeichnungen abgebildet, ihre bisher bekannte Verbrei- tung auf Karten dargestellt. Für A. formosa wird ein Neotypus festgelegt. Schlüsselwörter: Taxonomie, Anatomie, Agardhiella, neue Arten, Verbreitung. Abstract The Agardhiella species in the westerneschweizerbartxxx sng- part of their area of distribution are revised. Two species from Albania are described as new: Agardhiella extravaganta n. sp. and Agardhiella zoltanorum n. sp. All species are illustrated by photos and drawings. Their hitherto known area of distribution is presented on several maps. For A. formosa, a neotype is designated. Key words: Taxonomy, anatomy, Agardhiella, new species, distribution pattern. Introduction During several collecting trips of Hungarian mala- treated, i.e. Italy, Austria, Slovenia, Croatia, Bosnia and cologists to Albania, a number of yet unknown land snail Hercergovina, Montenegro, Albania and northwestern species have been discovered. These collectors entrusted Greece.

Comparing these specimens to material of this genus collected from Montenegro, two species from Albania Material and Methods turned out to be new to science and are described here. At the same time a revision of the Argninae is started to The shells of the species of Agardhiella are mainly increase the scarce knowledge of this subfamily. In the found in the debris of waterbodies, while records from first part of the revision, the Agardhiella-species of the primary habitats are extremely rare. This can be ex- western part of the distribution area of the genus will be plained by the cryptic way of life of these animals.
