Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Harzhauser et al. 2008 | Medium-sized, subquadrate tridacnine bivalve with sharp pseudocarina (sensu Schneider 1998), narrow dorsoventral angle and closed byssal gape. Pseudocarina with keel-like accentuated primary rib. Sculpture differentiated into broad primary ribs and weaker secondary ribs. Right hinge with a blunt posterior cardinal tooth and a very weak, largely reduced anterior denticle; left valve only with strong posterior cardinal tooth. Left valves develop a deeper posterior lateral socket and stronger laterals than the right valves. |
