Remarks
Vandel (1953: 52) originally classified this taxon as a subspecies of P. sexfasciatus . He indicated distinctive characters, including pronounced granulations ( Fig. 14A View Fig ), few pores in the glandular fields, cephalon with a small median lobe, and medium-sized lateral lobes. In males, the carpus of the pereopods 1 and 2 possess dense setae, and the exopod I has a widened inner lobe at the base, terminating in a fine, narrow point ( Figs 14C View Fig , 15A View Fig ). The b/c and d/c coordinates are relatively low ( Figs 2F, L View Fig , 14B View Fig ). Additionally, it is noteworthy that the scale-setae possess a broad tip ( Fig. 3F View Fig ). The male exopod of the pleopod II is triangular ( Figs 14D View Fig , 15B View Fig ). Females exhibit a minor incision in the tracheal field on exopods I and II ( Fig. 15C–D View Fig ). Considering the aforementioned, we consider that P. lucasioides ( Vandel, 1953) possesses sufficient distinct characters to be considered a valid species ( Table 1 View Table 1 ), rather than a subspecies of P. sexfasciatus .
In some specimens of both immature and adult P. lucasioides , the inner tip of the exopod I is occasionally underdeveloped, which increases the potential for misidentification with P. glabe r. However, distinguishing between these two species is feasible, as P. lucasioides has pronounced granulations and medium-sized lateral lobes on the cephalon, while P. glabe r either presents a smooth body or, in some specimens, may have sparse and very fine granulations on the cephalon, and lacks lateral lobes.
Distribution
Spanish providences of Almería: Fondón, Laujar de Andarax ( Vandel 1953) and Níjar ( Cifuentes 2021a); Ávila: Piedralaves ( Pollo Zorita 1986b); Córdoba: Morrón Grande ( Garcia 2019) and Venta del Charco ( Cifuentes 2021a); Cuenca: Ruinas de Segóbriga ( Pollo Zorita 1986a, 2015); Jaén: Peñas ( Garcia 2019).
It is recorded for the first time in the Spanish province of Murcia ( Fig. 16 View Fig ).
