Description: Body elongated and cylindric, translucent whitish with three white lines, the first one dorsal, beginning in the tip of the tail and bifurcating close to the oral tentacles, ending in the anterior of each rhinophores. Other two lines lateral, beginning in the basis of the last ceratae and ending in basis of the fist ceratae. Redorange spot on first five rhinophore lamellae, on medial region of oral tentacles. Basis of caratae dark or light brown, cnidosacs whitish. Conspicuous, well-developed head with black eyes posterior to the basis of the rhinophores; one pair of elongated, smooth oral tentacles, wide in the basis and pointed distally, more than twice as long as the rhinophores. One pair of retractile, lamellate, conical rhinophores with robust, basal projection. Dorsal surface smooth with lateral, smooth and elongated ceratae organized in rows. Posteriorly, smooth, elongated foot forming a narrow tail.
