Resumen de Isopods of the genus "Arcturella" (Valvifera: Arcturidae) from the expedition FAUNA I (S Spain), with description of a new species
L. Rodríguez Sánchez, Juan María Junoy Pintos
Three specimens of the genus Arcturella (Crustacea: Isopoda: Valvifera: Arcturidae) were collected in the oceanographic expedition FAUNA I (S Spain). The specimens are fully described and illustrated, and a new species, Arcturella estherae sp. nov., is established. The two female specimens of this new species can be distinguished from all other species of the genus chiefly by the shape and ornamentation of the pereonite IV. The third specimen resembles Arcturella carlosoteroi, but shows certain anatomical differences from the only known specimen of this species.
