Dongara, 6.0 metres, Western Australia, Australia, Indian Ocean, 15 March 2006, Subtidal limestone reef, SCUBA. Length: Approx. 3 cm. Photographer: Corey Whisson/Western Australian Museum.

Green elysiid with reddish brown mottling in the neck region and scattered white specks, caused by short white papillae on the body and external side of the parapodia. Microscopic black specks are also present. The rhinophores are relatively short and yellowish brown in colour. The most distinctive feature of this species is the presence of 50 or more large gill-like lamellae, on the inside of each parapodia. They sit at right angles to the parapodia edge and run from the edge of the parapodia to about halfway to the dorsal midline of the body.
