Galba truncatula (O. F. Mueller, 1774)

Fig. 14H, I

GenBank no.

COI: MZ027628-MZ027629

Remarks.

Common Palaearctic gastropod, inhabiting nearly all of Europe. This amphibious and calcifilous (e.g., Glöer 2019) species inhabits small water bodies, rich in vegetation, such as at our locality 16 - a small lake in a collapsed cave, rather than subterranean habitats, but at the locality 15 it was found in an estavelle, a kind of vast subterranean tunnel transporting water either down, as outlet of surface waters, or up, forming temporary active springs. Shells of our specimens (Fig. 14H, I ) were somewhat untypical, with low and broad spire, but the variation of the shell in the Lymnaeidae has been long known (e.g., Roszkowski 1914; Falniowski 1980, 1981), as being wider than in any other gastropod group.
