Remarks This species is characterized by a smooth integument (Fig. 6A), antennae without tubercles bearing scale-setae, and pereopod 7 without sexual dimorphism (Table 1). The male pleopod I endopod has a long and triangular lobe (Figs 6B, 7A), and the exopod is triangular (Figs 6C, 7B), with almost no notch and two nearly equal ciliated rami, with the external ramus slightly thinner and longer than the internal. The male pleopod II endopod (Figs 6D, 7C) has a distal segment 3.5 × the length of the basal segment, ending in a thin tip covered by a hyaline membrane, and the exopod II is trapezoidal (Figs 6D, 7D). This is an epigean species (Table 1). Distribution In Portugal, the species is recorded from the districts of Braga (Albergaria, Serra do Gerez), Porto (Fragas do Diabo) and Viana do Castelo (Carvoeiro, Castanheira, central Lindoso, Mantelàes, Vascões) (Vandel 1946; Gregory et al. 2012). In Spain, it is known from the provinces of A Coruña (Santiago), Cantabria (Ruente, Saja), León (Río Duerna, Posada), Orense (Avión, Beade, Beiro, Lobios) and Pontevedra (Amorín, As Eiras, Cangas, Gondomar, Marín, Oia, Puerto de Moncelos) (Schmölzer 1955, 1971; Gregory et al. 2012; Cifuentes 2019b). It is recorded for the first time in the district of Leiria, which is the southernmost record of this species in Portugal (Fig. 8).
