A single prominent rounded fleshy bulbous spine is present above each eye and on each cheek; spines otherwise absent. Body ornamentation is in the form of irregular prominent bulbous tubercles on the body and tail.

Colour is variable depending on the host gorgonian species. Individuals living on the gorgonian, Muricella plectana, are pale striated grey or purple with pink or red tubercles to match the gorgonian. Individuals living on M. paraplectana are yellow with orange/yellow tubercles. The tail is striped with dorsolateral circular markings.
