| Abstract |
Two new taxa belonging to the genus Acicula Hartmann, 1821, are described: A. giglioi n. sp., endemic from the Nebrodi Chain (north Sicily), and A. giglioi peloritana n. ssp., endemic from Peloritani Ridge (north-eastern Sicily). Their shells are characterized by the shape of the peristome: flattend, well separated from the last whorl of the spire, arched in lateral view and more or less strongly turned backwards in its upper part, crossed by several superficial striae. The two subspecific taxa differ from each other in the different character of the shell (height and diameter of shell, ratio H/D, number of striae in the penultimate whorl) and their distribution (Nebrodi and Peloritani mountains respectively). In addition, Acicula szigethyannae Subai, 1977 (Gastropoda Aciculidae), already known in peninsular Italy (from eastern Liguria to southern Calabria) and in eastern Sicily, is now confirmed as present in all central-eastern Sicily. |
