One transversal row of 11–12 stalked macrotubercles per chaetiger in midbody. Macrotubercle stalk about as long as or slightly longer than macrotubercle, with 1–3 small papillae along proximal half. Papillae on all body surfaces. 10–16 spherical papillae in front of each row of macrotubercles, somewhat arranged in a dorsal zig-zag row; 10–18 ventral papillae per chaetiger, most arranged in three more or less defined transversal rows: two on parapodial areas and one on interparapodial area, of usually 4, 6 and 5 papillae respectively. Females with a pair of oval, distally-opened tubercle-like structures located ventrally between parapodia of chaetigers 9–10. Males lacking any visible copulatory organs.
