Agardhiella tunde spec. nov. (Gastropoda: Pulmonata: Argnidae), a new endemic land snail from Romania

Agardhiella tunde spec. nov. is described from the Piscuri Gorge (N of Vâlcele), Vâlcan Mts., Romania. Another population of this species has been found in the Sohodol Gorge (N of Runcu) and in the Susita Valley (N of Pârvulesti). Owing to the trapezoid shape of the aperture, this taxon resembles mainly Agardhiella banatica (Zilch 1958); however, it is different considering the structure of the palatal and basal folds of the aperture, and the presence of a parietal lamella and a palatal tooth. The new species and the accompanying fauna observed on its localities can, in zoogeographical terms, be well integrated into the Banaticum fauna characterized by the abundance of Carpathian and Balkan elements and endemisms.
