Brada rugosa.— Støp-Bowitz 1948a: 37 –40, Fig. 10 (syn.).— Støp-Bowitz 1948b: 41 –42, map.— Jirkov & Filippova 2001: 355, Figs 1–4.— Oug et al. 2011: 13, Figs a, b. (repeated from Støp-Bowitz 1948a). Type material. Northwestern European Arctic Ocean. Syntypes (ZMUB 2288), Norwegian North Atlantic Expedition, Sta. 366 (79°35' N, 11°17' E), NW Svalbard, 68 m (after Hansen 1882:23), 1877. Description. Two syntypes (ZMUB 2288, Figs 1C, 17A, B) with all neurochaetae broken. One syntype whitish (more damaged), body truncate in both ends, soft, dissected anteroventrally and several parapodia removed; the other syntype yellowish, truncate, wider anteriorly, tapered posteriorly, rough, several parapodia removed; 34–38 mm long, 7–8 mm wide, cephalic cage 5.0– 5.5 mm long, 21–25 chaetigers. Tunic rugose, dorsal and ventral papillae forming incomplete transverse tuberculose ridges, arranged in 3–4 transverse rowsseries per chaetiger; each tubercle covered by a thin layer of fine sediment particles. Cephalic hood not exposed; dissected syntype without anterior end (missing). Additional dissection avoided. Anterior end features unknown. Cephalic cage chaetae as long as 1/6 body length, or more than half as long as body width. Chaetiger 1 involved in cephalic cage; chaetae arranged in short lateral series; 10 notochaetae and 10 neurochaetae per side (most remain in yellowish syntype, Fig. 17C). Anterior dorsal margin of first chaetiger papillated, papillae small, abundant (most eroded). Anterior chaetigers without especially long papillae. Chaetigers 1–3 of similar length but notopodia in chaetiger 2 larger than others. Chaetal transition from cephalic cage to body chaetae abrupt; chaetiger 2 with neurospines (broken). Gonopodial lobes small, rounded, ...
