Prodissoconch 170 µm long. Left valve with reticulate sculpture of weak unevenly spaced radial costae and slightly more prominent commarginal lamellae, interstices microscopically scratched. Radial and commarginal sculpture commence in early ontogeny, c. 1 mmbelow umbonal top. Radial riblets increasing in prominence towards ventral margin. Anterior auricle with coarser commarginal lamellae than posterior one, lacking radial riblets. Right valve with commarginal lamellae, somewhat higher and coarser at ventral margin than higher up, interstices with microscopic scratches. Anterior and posterior auricles also with commarginal lamellae, slightly more irregular on anterior one. Byssal fasciole small, byssal notch hardly distinguished from outer margin of anterior auricle. Hinge line almost straight. Hinge dentition with strong irregular grooves. Internal ribs lacking. Type material examined: Holotype(pr): AMS C.155831.1.  Paratypes(47 v): AMS C.155800, C.155813, C.155814, C.155822, C.155823, C.155831.2, C.155832, C.155837. See Dijkstra (1990 b: 31). Other material examined:  MOZAMBIQUECHANNEL: Zambezetransect ( 19°36'S 36°47'E), -  636 m, live, campaign Mainbaza, stn CC3154,  13.iv.2009( MNHN);  Maputotransect ( 25°13'S 35°21'E), -  700–707 m, live, campaign Mainbaza, stn CP3138,  10.iv.2009( MNHN);  Maputotransect ( 23°33'S 35°55'E), -  684–698 m, dead, campaign Mainbaza, stn CP3141,  11.iv.2009( MNHN);  Inhambanetransect ( 24°22'S 35°42'E), -  708–715 m, live, campaign Mainbaza, stn CC3166,  15.iv.2009( MNHN). S  MADAGASCAR: Sainte Luce( 24°43'S 47°32'E), -  296–307 m, dead, expedition Atimo Vatae, stn DW3534, RV Nosy Bé11,  02.v.2010( MNHN);  Lavanono( 25°43'S 44°24'E), -  729–732 m, dead, expedition Atimo Vatae, stn CP3597, RV Nosy Bé11,  12.v.2010( MNHN);  S Cap Sainte Marie( 26°14'S 45°09'E), -  284–286 m, dead, expedition Atimo Vatae, stn CP3615, RV Nosy Bé11,  14.v.2010( MNHN). Distribution and habitat: Solomon Islands( Dijkstra & Maestrati 2008: 97), southeastern Australia(Dijkstra 1990 b: 29), Norfolk Islandand Kermadec Islands ( Dijkstra & Marshall 1997: 17), Vanuatu(Dijkstra & Maestrati 2012: 393). Now also extended into the southwestern Indian Ocean, from the MozambiqueChannel and southern Madagascar(new record). Living bathyally (- 512–914 m) on soft substrata of mud and sand with sediments. Present specimens live at - 707–708 m(minimum depth range). Remarks: Present specimens from the MozambiqueChannel and southern Madagascarare morphologically indistinguishable from the typematerial. The reticulate sculpture on the left valve is somewhat variable in prominence of the present material, but this feature is also observed in material from the southwestern Pacific (MNHN).
