Opercular peduncle or operculum absent; however, the radioles sometimes with the tips and/or pinnules swollen. Thorax with 8–11 chaetigers. Collar with fin-and-blade chaetae, with proximal denticulate expansion separate of the distal limbate zone, with 3–6 large teeth ( Fig. 10I). All thoracic chaetigers (except collar segment) with “ Apomatus   ” chaetae ( Fig. 10J). Thoracic uncini rasp shaped, with 8–9 rows of teeth and 3–4 teeth in each row. Abdomen with 26– 29 chaetigers.

Habitat. Depth: Intertidal to 2 m. On dead coral. Fouling species.
