. Ellipsoid body with strongly convex dorsum. Four longitudinal rows of sessile and spherical (sometimes pear-shaped) dorsal macrotubercles and three transversal rows (total up to 11) of dorsal spherical papillae per segment. Distance between dorsal-most macrotubercles exceeding distance between those and lateral ones. Parapodia with long digitiform acicular lobe, shorter ventral cirrus and a single rounded papilla on anterior distal end. Four or five chaetae per parapodium, with thin shafts slightly enlarged distally and lacking spinulation, and short blades (5–7 times longer than wide), serrated and with smooth distal end. Males with ‘copulatory organ’ as conical papillae ventral to ventral cirri between chaetiger 6 and 7.

Parapodia do not exceed twice the length of the width. Number of chaetae range between 4–5 per parapodium. Length of blades shows a slight variation in number of chaetae and the relative length of blades. Examined specimens are not transparent and muscular pharynx was not conspicuous.
