Material examined: Praia de Baia Formosa, Baia Formosa, 05.VII.2009, one specimen, 3 mm (body length), leg. M. Delgado ( GEEFAA 289).

Description: Elongated and cylindrical body. It has a whitish translucent background, with the whitish back cut by two lateral orange lines from the oral tentacles to the base of the last cerata, very translucent at the beginning of the oral tentacles. From the median to the ends the color changes to a light yellow, almost beige, the rhinophores have an orange base, yellowish in the medial region and translucent in the apical region. Cerata have a translucent color with soft spots in a light orange tone, with yellowish cnidosacs. In the anterior portion there is a prominent head with lateral eyes and, below the base of the rhinophores, smooth oral tentacles and a gradually thin thickness at the tip. Elongate and lamellated rhinophores with tips thinner than the base, with an oblique angle. In the medial region, there are very long and thin cerata, arranged in pairs of six rows on the lateral side. The muscular foot is broad and flat, becoming well tapered in the posterior portion, forming a slender tail.
