Calcinus californiensis Bouvier, 1898

Material examined. Six males (ICMyL MAZ 9038A) form Islas Marietas and one female from the Huatulco region (ICMyL MAZ 9055).

Remarks. The distribution of this species has been from the Gulf of California to the Acapulco region and the west coast of the Baja California peninsula (Brusca 1980). There is a sibling species (C. explorator Boone 1930) whose distribution ranges from the central-south Mexican Pacific to the Galápagos Islands (Brusca 1980). However, the sampled material was determined as C. californiensis because of its color pattern of the walking legs (Brusca 1980). Our data, sampled south of the Acapulco region (its previous geographic limit), is the southernmost limit for the species in the Eastern Pacific, increasing its range about 350 km south.
