Distribution. East Pacific, from California and western Mexico; Indian Ocean (Ibarra Rivera & Hendrickx 2008). In western Mexico it has been reported throughout the central-southern Gulf of California (Ibarra Rivera & Hendrickx 2008) and it is herein reported from several localities along the west coast of the Baja California Peninsula (Fig. 5).

Remarks. With 108 specimens collected during this survey in only three stations, G. scapularis was by far the most numerous species in the samples.
