Tricolia landinii, una nuova specie per le coste orientali della Sicilia

We report here on some Tricolia specimens found in scattered localities in the vicinity of the Strait of Messina (Calabria and eastern Sicily), which we could not assign to any of the known Mediterranean species from shell morphology. These were considered to be a new species, named Tricolia landiniii after Fabio Landini who was also studying this species in the last days of his life. Characters of the new species are compared to those found in Mediterranean congeners. This new species further increases the number of endemic species of the area.
