Es cita per primera vegada a les costes de Balears Pachygrapsus transversus (Gibbes, 1850). La presencia d'aquesta especie a les nostres costes només pot esser explicable al seu transport involuntari per medi de vaixells, tal com ja s'ha constatat a altres indrets. Es comenta breument la importancia deis vaixells en la dispersió recent per la Mediterrania d'algunes especies de eran cs.

Pachygrapsus transversus (Gibbes, 1850) is first recorded from the coast of the Balearics Islands. Its presence here can only be explained by involuntary passive transport by means of ships, as has also been recorded for other sites. The relevance of ships in the recent dispersal of some species of crabs in the Mediterranean is discussed.
