Remarks

The record of Caprella santosrosai on the coast of Ceuta represents the ®rst for this species since its original description (SaÂnchez-Moyano et al., 1995b). Although this species was fully described, we have included complete ®gures because several diOEerences have been found between specimens from southern Spain and northern Africa. The general lateral view is very similar. However the mouthparts and abdomen are diOEerent: (1) in specimens collected from Ceuta the outer lobe of the maxilliped has four teeth and the inner lobe three, while in the specimens from southern Spain it has three and two respectively; (2) specimens from Ceuta have no plumose seta on the outer lobe of maxilla 1, while this seta, which is rare among species of Caprella , is present in specimens from southern Spain; (3) the most remarkable diOEerences are found in the male abdomen; while specimens from Ceuta have the ®rst pair of pleopods clearly biarticulate, no distinct articulation was found in the specimens from southern Spain (SaÂnchez-Moyano et al., 1995b). Furthermore, the distal article of the ®rst pleopods is serrated on the apical margin in male specimens from Ceuta, whereas it is smooth in specimens from southern Spain.
