A remarkable new record of the Iberian freshwater mollusc Corbellaria celtiberica Callot-Girardi & Boeters, 2012 (Gastropoda: Hydrobiidae) in Spain

A new, isolated, population of the endemic Iberian hydrobiid Corbellaria celtiberica has been located, based on shells at the eastern foothills of the Iberian System (Province of Castellón, Valencian Community, Spain). The shells are biometrically studied and compared with shells from the type locality and with additional data from the literature. The finding of this new population considerably expands the previously known distribution area of the species.
