  Further records of two uncommon Crustaceans in Italian seas: Maja goltziana D'Oliveira, 1888 (Decapoda Brachyura Majidae) and Xaiva biguttata (Risso, 1816) (Decapoda Brachyura Portunidae)

  ABSTRACT
  The presence of Maja goltziana D'Oliveira, 1888 (Decapoda Brachyura Majidae) is confirmed in the central Tyrrhenian Sea and in the Tuscan archipelago. Xaiva biguttata (Risso, 1816) (Decapoda Brachyura Portunidae) is first recorded from the Western Sardinian coast and the Eastern Sicilian coast. The presence and spread of M. goltziana are considered a consequence of climatic changes. The presence of X. biguttata in Italian seas was probably underestimated, and its supposed rarity should be reassessed.
