Abstract |
During the expeditions FAUNA IBERICA II and CANGREXO I off the coast of the Iberian peninsula, eighteen specimens of Luitfriedia minuta gen. et sp. nov., were collected in Galicia (NW Spain). The new species, which belongs to the sub-family Eleutheromeniinae of the family Pararrhopaliidae, is characterized by a thick cuticle with hollow, acicular and hooked spicules; a pedal groove with one fold that does not enter the pallial cavity; the absence of a radula and a radular sac rudimentary; no dorsal pharyngeal gland; the ventral foregut glandular organs belong to the type A (according to Salvini-Plawen, 1978); the midgut is devoid of a dorsal caecum; the posterior-most sole glands are enlarged and the unpaired genital orifice has a muscular sphincter. There are no copulatory and abdominal spicules; ten to twelve respiratory folds are present. The features of the new species are discussed and compared with those of other species of the subfamily. |
