GenBank no.

COI: MW879254-MW879255

Remarks.

Considering the shell morphology, it should be determined as A. fluviatilis O. F. Müller, 1774, a species reported from this region. However, Pfenninger et al. (2003) demonstrated that A. fluviatilis inhabits a wide range throughout Europe, but in the southern regions there are a few cryptic, molecularly defined species of Ancylus . Our Ancylus sp. molecularly belonged to the Clade 4 of Pfenninger et al. (2003) and " Ancylus sp. C4" of Albrecht et al. (2006) (Fig. 15). It was found as a crenobiont in the cave springs at the localities 8, 9 and 16 (Fig. 4). Molecular divergence between this Ancylus sp. and Ancylus recurvus is 7%, and similar value (7.5%) is observed between this Ancylus sp. and A. fluviatilis .
