Remarks.

Ancylus is known as a stygophile gastropod (e.g., Culver and Pipan 2009; Macher et al. 2016; personal observations); also inhabiting caves. Ancylus recurvus at the locality 13 was also found interstitially, pumped, and at the locality 15 (Fig. 4) it inhabited an estavelle. Our A. recurvus molecularly belonged to the clade " Ancylus sp. B" of Albrecht et al. (2006), Clade 3 of Pfenninger et al. (2003) (Fig. 15). It is molecularly different from A. fluviatilis by 9%.
