Non type material. One specimen ( MNCN 16.01/16626), COCACE station I6 (43.92°N – 06.11°W), 1186 m depth, 38% sand, 30% silt, 32% clay, Cantabrian Sea, Bay of Biscay, 0 4 Jul 1987; 1 specimen ( MNCN 16.01/ 16627), Prieto Cape (Asturias), 43º 49.10’ N, 04º 52.74’ W –43º 49.33 N, 04º 53.47’ W, 925–1025 m depth, Cantabrian Sea, Bay of Biscay, 25 Jun 1991, coll. Fauna Ibérica II. Several from the same locality for SEM studies.

All specimens incomplete, lacking posterior ends; smallest specimen measuring 11 mm for 48 chaetigers, width 0.3 mm; largest specimen measuring 22 mm in length for 76 chaetigers, width 0.6 mm.

Diagnosis. Eyes absent; palps reaching chaetiger 1, lateral antennae reaching chaetiger 3, median antenna reaching chaetiger 2; ceratophores of antennae and palps with 4–5 rings and lateral projections of variable distribution ( Fig. 4 B). Peristomial cirri present ( Fig. 4 B). Anterior three pairs of parapodia modified ( Fig. 4 A); ventral cirri subulate on first three chaetigers, ventral glandular pads with a continuous row of pores along the length of the glandular pad ( Fig. 11 A, B); subulate postchaetal lobes absent from chaetiger 8 ( Fig. 4 A). Modified parapodia with bi- and tridentate pseudocompound hooks with moderately long pointed hoods; subacicular hooks starting from chaetiger 11, pectinate chaetae with oblique combs with 14–17 teeth ( Fig. 4 C). Branchiae absent.

Distribution. Cantabrian slope and Capbreton and Avilés submarine canyons, Cantabrian Sea, Bay of Biscay, East Atlantic.
