Description. Length 7 to 17 mm, width 0.7 to 1.6 mm. Prostomium with middle lobe delimited by incision, without glandular ridges or eyes ( Fig. 4View FIGURE 4 A). Buccal tentacles without groove, densely covered with long and slender pinnae ( Fig. 4View FIGURE 4 B). 4 pairs of indistinctly annulated, cirriform branchiae in transverse lines in fused segments II + III, with 4 th pair usually displaced slightly caudally; branchial groups separated by wide median gap; branchiae of segment II in 2 nd outermost position, branchiae of segment III in outermost position, branchiae of segment IV in innermost position, branchiae of segment V in 2 nd innermost position, shifted slightly caudally ( Figs. 4View FIGURE 4 C, D; 6 D). 8–12 chaetae in fused segments II + III, slightly thicker and longer than regular notochaetae. Numbers on both sides differing by 1 in each specimen. Notopodia with regular capillary notochaetae from segment IV, present in 14 chaetigers ( Fig. 4View FIGURE 4 E). Neuropodial tori with uncini from segment VI, present in 12 thoracic uncinigers. Cirri and papillae in thoracic parapodia absent. Continuous ventral shields present to thoracic unciniger 10. Elevated or modified notopodia absent. 2 intermediate uncinigers. 10 abdominal uncinigers. Glandular pads above pinnules present in intermediate and abdominal uncinigers. Pinnules with small dorsal papilla ( Fig. 4View FIGURE 4 F). Pygidium with terminal anus, surrounded by 1 pair of lateral, cirriform anal cirri, inserted sub-terminally, and a ring of papillae ( Fig. 4View FIGURE 4 G). 1 pair of nephridial papillae in segment IV, located posterior to innermost branchiae. Thoracic and abdominal uncini with 9 teeth in 2 alternating rows over basal prow and rostral tooth ( Figs. 4View FIGURE 4 H, I). Faint reddish brown stripe along body on both sides, located between notopodia and tori in thorax, continuing in the abdominal glandular pads; prostomium, peristomium, and ventral shields also faintly pigmented.

Distribution. North Atlantic from Nova Scotia, New Foundland, and the Gulf of St. Lawrence over Iceland, the Irish Sea, to Spitsbergen and the North Sea as far east as the Kattegat; White Sea; North Pacific including the Japanese coast (105–480m). The species has been recorded from a wide depth range from 8 to 1940 m.
