Type data. Holotype (pr) NHMUK 1887.2.9.3281. Type locality: NW Coral Sea, E of Cape York (N QLD), 12°08'S 145°10'E, alive, 2561 m (Challenger stn 184). GoogleMaps

Comments on type data. The holotype is an articulated specimen without soft parts. Probably these were removed during preservation. It is most likely that this specimen was collected alive, as dead-collected specimens always consist of separate valves because of their very weak ligament.

Description. Shell small, c. 15 mm high, fragile, almost circular, inequivalve, opaque, left valve somewhat more convex than right valve, auricles unequal, umbonal angle c. 95°.

Left valve sculptured with closely spaced commarginal lamellae, less prominent on right valve, more closely spaced near ventral margin. Auricles delimited from shell disc. Microsculpture of weak interstitial antimarginal threads.

Right valve almost flat, with minute commarginal lamellae. Posterior auricle delimited; anterior auricle distinct from shell disc, with deep byssal notch. Dorsal margin straight.

Distribution. The only other material recorded to date is that by Dijkstra & Marshall (2008: 39, fig. 33) from the Lord Howe Rise (34°31.5'S 166°21'E, 2928–2930 m; 2 v, NMNZ M.274123; 2 v, NIWA U195). The known distribution is therefore the Coral Sea and Lord Howe Rise, in 2561–2930 m.

Remarks. Specimens from the Lord Howe Rise are smaller than the holotype (height c. 10.5 mm versus c. 14.5 mm) but are otherwise identical.
