DISTRIBUTION. — Indonesian Archipelago and Solomon Islands ( Dijkstra & Maestrati 2008: 87). Depth range 281-655 m (dead). Austral Islands, only loose valves at 176-750 m depth.

REMARKS

The present specimens are similar to the type material. The radial riblets of the left valve are unevenly, widely spaced and more pronounced than the commarginal lamellae, which are microscopically closely spaced. External and internal sculpture is rather constant.
