Branchiae cirriform, sessile on branchial plate, arranged as two concentric rows, posterior row continuous with about 12 branchial scars, anterior row separated in two lateral groups, each with four branchial scars, making 20 total filaments. Size relationships between palps and branchiae unknown. Cephalic cage chaetae about as long as body length, or four times longer than body width. Cephalic cage made only by chaetigers 1-2, with chaetiger 2 slightly displaced dorsally. Chaetiger 3 with chaetae long but less than half those present in chaetiger 2. Cephalic cage chaetae arranged in short series, lateral, four-five chaetae per chaetal lobe. Anterior dorsal margin of first chaetiger papillated. Chaetigers 1-2 with long papillae over their chaetal lobes, longer than following chaetigers. Post-cephalic cage chaetigers not elongated; only chaetiger 3 longer. No constriction behind those chaetigers forming the cephalic cage; parapodia of chaetigers 1-2 better developed than posterior ones. A crescentic glandular pad with a smaller portion on chaetiger 1. Chaetal transition from cephalic cage to body chaetae abrupt; pseudocompound neurohooks from chaetiger 4. Gonopodial lobes not seen. Parapodia better developed in chaetigers 1-2; following ones poorly developed; chaetae emerging from the body wall. Notopodia with longer papillae than neuropodia (
