The specimens of this species can reach more than 20 mm in length. The head is small and rhinophores are short and curled. The eyes are behind the base of the rhinophores. The parapodia are quite large, with a scalloped or undulating edge and have small conical tubercles which are also found in smaller quantities in the inner and outer parapodia. The overall body color is yellowish-green more or less homogeneous, except on the edge of the parapodia and the tubercules, which are white. With the aid of a binocular microscopy small reddish spots can be seen in the head and on the inner side of the parapodia. There are whitish granulations that conform a curved line extending from the anterior edge of the parapodia until the prominence of the heart, located in the region of the back, where the parapodia start. From the cardiac area there can be seen, by transparency, two thick greenish nervations, one on each side of the body, belonging to the digestive gland, that progressively branch towards the edges of the parapodia. The foot is also yellowish-green color, with a short tail behind the back of the parapodia.
There is no information regarding its preferred habitat, the algae that feeds on, nor reproduction.
