First record of the marine snail Xenophora crispa (Gastropoda: Xenophoridae) from Madeira Island (Northeastern Atlantic Ocean)

First record of Xenophora crispa from Madeira Island

Abstract

The marine snail Xenophora crispa (d' Orbigny, 1847) is recorded for the first time in Madeira Island (NE Atlantic). This species is currently distributed throughout the central and western Mediterranean, western Atlantic from France (Gulf of Biscay) to North Africa (up to Morocco) including the Archipelagos of the Azores, Canary Islands, and now Madeira. Taxonomic features and similarities between Xenophora crispa (d' Orbigny, 1847) and Xenophora senegalensis P. Fischer, 1873, are discussed, highlighting relevant morphological differences described in the bibliography.
