MATERIAL EXAMINED. — New Guinea. NE, 1957 m, lectotype spm (BMNH 1887.2.9.3307, designated by Dijkstra [1995a: 24]).

Rapa. BENTHAUS, stn CP 1911, 27°38’S, 144°15’W, 900-1300 m, 1 lv, 1 rv.

DISTRIBUTION. — Northern Indian Ocean, southern Japan, Papua New Guinea, New Caledonia, and Vanuatu (Dijkstra 2001: 82). Depth range 650-1300 m (alive). Now also Austral Islands (new record), only single valves at 900 m depth.

REMARKS

The left and right valves are similar to the type material, although the commarginal lamellae on the left valve are somewhat more closely arranged (intermediate lamellar space is variable). Other shell characters are identical to the type material.
