Diagnosis. Operculum with slanting, flat to subconical endplate, sometimes with smooth surface but most typically with 10–20 radiating ridges ending in as many marginal teeth. In fresh material a very diagnostic feature is the intensely red band of single lensed ocelli in the ventral edge of the opercular ampulla immediately below the calcareous endplate, thinning out towards the dorsal side ( Fig. 21 B–D). However, ocelli are difficult to see in preserved material. Peduncular wings with entire edge, at most slightly crenulated, but terminal digitate processes absent.

Remarks. Tube may be difficult to find, deeply imbedded into substrate and having a greenish to pink tinge in fresh material. The material from North Point still showed the typical band of ocelli in their opercula upon reexamination in 2015.

Distribution. Qld Australia, widely distributed in the Indo-West Pacific.
