Janulus spadinii n. sp. (Gastropoda, Pulmonata, Gastrodontidae) is described herein from the Zanclean (early Pliocene) of Baize di Caspreno (Tuscany).

Abstract
Janulus spadinii n. sp. (Gastropoda, Pulmonata, Gastrodontidae) is described herein from the Zanclean (early Pliocene) of Baize di Caspreno (Tuscany). It belongs to a Macaronesian genus occasionally reported from the Tertiary of Europe. The new species is very similar to the Recent Madeiran Janulus stephanophorus by virtue of its shape, dorsal sculpture and radial rows of palatal teeth. It is also apparently similar to some fossil European species, however, due to insufficient information regarding the latter, no well supported distinction may be proposed at present. A brief survey of all the nominal taxa of the species-group assigned to Janulus is also provided.File | Dimensione | Formato | |
