The body is translucent clear with a series of large dark patches along the midline of the notum and on the head. These patches appear greenish but are composed of a dense aggregation of small spots which range in colour from green to black. There are similar dark patches on the sides of the body below the cerata. Scattered all over the body are opaque white specks, which are much more numerous in the lighter parts of the body. The ducts of the digestive gland in the cerata are brown. The ceratal wall is translucent with scattered opaque white specks, and a dark greenish median band. The smooth tapering rhinophores are translucent with scattered white specks in the basal third, then a dark median band of blackish blotches, and an upper third which is opaque white. It is been previously reported as Cuthona sp. 1 (Hermosillo & Behrens, 2005), Cuthona sp. 2 (Camacho-Garcia et al, 2005; Hermosillo et al., 2006) and Cuthona sp. 4 (Behrens & Hermosillo, 2005)
