(2005). Body orange-brown with microscopic blue dots and small yellow tubercles. Parapodia with straight edge, pigmented with brown along its entire length or in segments. In live animal parapodia enter in contact with each other in center of body, becoming separate towards posterior and anterior ends. In area of contact there is an olive-oil elongate patch with a bright blue spot on its anterior half and snow white pigment on its posterior half.

of the body with 2–3 snow white conical papillae with blue pigment around their bases. Head white or orange with blue spots and two orange lines running from eyes to parapodia and several ramified green lines. Foot sole translucent orange with viscera visible through skin. Rhinophores elongate, about ¼ of total length of animal, reddish-brown with small white papillae.
