Ancylus recurvus Martens, 1783

Fig. 14J, K

GenBank no.

COI: MW879251-MW879253

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%.
