First branchiae dorsal to notosetae of setiger 1 lateral to dorsal tentacles; subsequent branchiae also dorsal to notosetae. Thoracic parapodia well developed dorso-lateral lobes with notopodia forming shoulders; setae emerge ventro-laterally from slightly swollen regions of body wall in abdominal segments.
