This article presents an isopod that arrived at the Geological Museum of the Seminary, Barcelona (Spain) a few years ago, as part of the material compiled by the first author of this article (J C) in an outcrop of Gara es Sbâa (Morocco). This isopod is identified as Unusuropode castroi, is the first reference to this species outside of Brazil and also represents the first formal description of Unusuropode castroi in Africa. Gara is Sbâa, is located in the region of Kem Kem (southeast of Morocco) and is presented as a new locality for the isopod Unusuropode castroi, from the Upper Cretaceous (Cenomanian / Turonian), previously described only in the Turonian of the Apodi Group, Arenito Açu, state of Ceará Brazil. With this new isopod the statement of Martill et al. [1] is reinforced, indicating the affinities between the faunas of South America and Morocco during the Cretaceous. This document presents the two types of Unusuropode castroi differentiated by their size that also appear in Brazil, described by Duarte and Santos [2] as possible sexual dimorphism (see table 1 and figure 5, images b – c).
