Extendeddiagnosis . Body narrow. Fivetoeight pairs (commonly more than six) of branched dorsolateral appendages, digestive gland penetrates at least three pairs of dorolateral appendages. Four to six appendages of oral veil. Four to six appendages of rhinophoral stalks. Lateral papilla of rhinophoral sheaths present. Rhinophoreswith 11–15 lamellae. Five to ten lip papillae. Basal colour white, dorsolateral appendage variable opaque orange or opaque white, including tip. Dorsal processes of jaws inclined posteriorly at approximately 50–60° to the longitudinal axis of the jaw body and 0.43–0.45 of its length. Radula with up to 43 rows of teeth.
