There is a tentacle over each eye, consisting of a short, flat, fleshy stalk with a short fringe of fine cirri at the end. The head is pointed, with a bluntly wedge-shaped snout and the space between the eyes is convex. The mouth opening is small, with the lower jaw slightly longer than upper and thick lips.[3][4] The dorsal fin has no crest.[5] Cirri on the front nostrils are elongate, spatulate, and slightly lobed ventrally.[4]

There is a white band from the dorsal fin between the eyes to the snout, and a brown band from the eyes to the snout, extending onto the lower lip. The outer edge of the dorsal and analdins and the tip of the caudal fin are white. The inner half of the ventral fins is white and the outer part is reddish brown.[3][5]
