Distinctive colour pattern of 2 transverse purple to Brown bands across anterior chaetigers. Antennae, tentacular cirri and dorsal cirri long and slender, distinctly articulated. Pharynx extend over 6-7 chaetigers with large conical tooth set back from anterior margin, proventicle over ~ 4 chaetigers.
First found on coralline algae outside abalone farm, in higher densities on experimental Holothuria scabra farm. Could potentially damage cucumbers, but conclusive evidence lacking.
