ResumenParental care and extended parental care are known behaviours in decapod crustaceans (see Thiel, 2000, 2003). While parental care before hatching, which involves incubation of the eggs (carrying, cleaning, and aeration) by females, is a common behaviour in the majority of decapod taxa (with the exception of Dendrobranchiata), extended parental care is a rare behaviour in decapods, restricted only to some species of brachyuran crabs (Diesel, 1989, 1992, 1997; Diesel & Horst, 1995; Ng & Tan, 1995), hermit crabs (Hazlett, 1983; López Greco et al., 2004; Calado et al., 2006), astacid crayfishes (Johnston & Fiegel, 1997; Vogt & Tolley, 2004), and caridean shrimps (Duffy, 1996). In the majority of these cases, the parental female presents different types of parental activity towards the offspring after hatching, like habitat control, elimination of predators, or sharing meals. Also, there are some cases in which larvae develop transient structures that allow them to remain fixed to the pleopods of the female abdomen, like in astacids (see Vogt & Tolley, 2004) and several species of the genus Sclerocrangon Sars, 1883 (see Makarov, 1968; Lacoursière-Roussel & Sainte-Marie, 2009). However, the most infrequent cases of extended parental care in decapods are those where females carry their juvenile offspring under their abdomen after the hatched larvae develop there (cf. abdominal brood pouches, or incubation chamber). These cases have only been reported in one species of Brachyura, Tunicotheres moseri (Rathbun, 1918) (see Bolaños et al., 2004), and one caridean, the kangaroo shrimp Dugastella valentina (Ferrer Galdiano, 1924) (see Cuesta et al., 2006). Taking into account this last case, and considering that there are only two species in the genus Dugastella Bouvier, 1912, the objective of the present study was to corroborate whether the other species, D. marocana Bouvier, 1912, also presents the same behaviour. These two species have a a restricted distribution, D. valentina occurs in the Gulf of Valencia (southern Europe) and D. marocana is found in some localities of Morocco (northwestern Africa).
