Spiralix calida sp. nov. (Gastropoda: Moitessieriidae), una nova espècie de gastròpode estigobi de Toga (l'Alt Millars, País Valèncià, Espanya)

Spiralix calida sp. nov. (Gastropoda: Moitessieriidae), a new species of stygobiont gastropod from Toga (l’Alt Millars, Valencian Country, Spain).—A new stygobiont snail, Spiralix (Spiralix) calida sp. nov. (Gastropoda: Moitessieriidae), is described based on shells from Font Calenta (Toga, l’Alt Millars, Valencian Country), in the province of Castellon. The new taxon differs from French species of the same genus by lacking a conspicuous teleoconch ornamentation, thus more closely resembling the various species of Spiralix previously known from Spain, from which it differs by size, the number of whorls and/or the less conical and slenderer shape of the shell. The description of this taxon reinforces the significance of the Iberian Levant (in particular, the provinces of Castellon and Valencia) as a diversity hotspot of this genus
