Typical shape for Crosslandia with bilobed parapodia, the anterior lobe being larger than the posterior. Edge of lobes described by Poorman & Mulliner as 'irregularly notched and digitate'. Colour described as 'greenish brown-orange: longitudinal fine chestnut brown lines with some white lines on sides and undersides of lobes; a narrow light-coloured border along the thin edge of the rhinophores sheaths, along the sides of the neck, round edge of lobes and crest of tail; irregular black to brown blotches on some animals. Brilliant blue small round spots medially along sides of body, about 6 in number, about 5 spots medially on the dorsum, most spots with fine black borders. A row of 4-6 flesh-colored, sharply conical tubercles along the median line of each side of the animal.' The animals were reported from Sonora, Mexico, on Padina where it grazes on small hydroids growing on the algae. It grows to 25mm in length.
