Remarks.

Cystodytes roseolus might have been found in Atlantic Panama in 2003 but identification needs to be confirmed due to the disjunct distribution ( Rocha et al. 2005). This second report of the species in the Gulf of Mexico indicates that this species occurs on both sides of the Atlantic. Finding this species in Progreso Harbor and nearby locations suggests that this species was introduced to the Yucatán peninsula from Africa by ship transport.

Global distribution.

Senegal ( Pérès 1949; Monniot 1969; Lafargue and Wahl 1987; Monniot and Monniot 1994), South Africa ( Hartmeyer 1912; Michaelsen 1919, 1934; Millar 1962), Seychelles ( Michaelsen 1919).
