Baba notes that the animal has elongate anterior foot corners and 'exceeding elongate' cerata. The colour is distinctive with orange red spots scattered on the head, back, sides and lower half of the cerata. The oral tentacles and upper half of the rhinophores are orange yellow. The upper half of the cerata is dusted with opaque white and the cerata are tipped with yellow. 5-7mm long.
