This species has similarities to Cerberilla annulata in colour but in that species the yellow and black bands on the cerata are bands of regular width and outlined in white. In C. asamusiensis the yellow-orange region covers a broad section of the upper ceras and the black region is cap-shaped. It also differs in the blackinsh rhinophres and the black line that runs across the front of the head and along the front edge of the oral tentcales to join the black upper half of the oral tentacles.
