摘要

The non-indigenous crustaceans Erugosquilla massavensis (Stomatopoda, Squillidae), Penaeus aztecus (Decapoda, Penaeidae) and Portunus segnis (Decapoda, Portunidae) are reported for the first time from the southern Tyrrhenian Sea (Gulf of Castellammare, NW Sicily) as a consequence of distribution range expansion. Their size and weight are provided along with the main distinguishing morphological characters. The presumed impacts on the ecosystem and the possible effect on the small-scale fishery of the Gulf of Castellammare are briefly discussed.
