Maja goltziana d'Oliveira, 1888 (Decapoda, Brachyura, Majidae) in the southern Tyrrhenian Sea.

Maja goltziana d’Oliveira, 1888 is an oxyrhynch crab occurring in the eastern Atlantic Ocean from Portugal to Congo and the Canary Islands, and in the Mediterranean Sea (d’Udekem d’Acoz, 1999). It is apparently uncommon all across its distributional range, although González Pérez (1995) describes it as a frequent species on the Canary Islands. In the Mediterranean, it is by far the least common of the Maja species, among which it can easily be distinguished by the morphological characteristics of the dorsal part of the carapace and of the walking legs. The present paper reports about two findings of M. goltziana in the southern Tyrrhenian, and confirms its established presence in the western Mediterranean Sea.
