Epicodakia consettiana Iredale, 1930 Description: A medium-sized, thick-shelled lucinid. Shape oval, longer than high, moderately inflated, umbo posterior to midline, lunule shallow. Exterior with commarginal ridges crossed by narrow, low radial threads forming small oval-shaped beads at intersections. Interior smooth, margin weakly crenulate; posterior muscle scar oval, anterior more elongate; pallial line entire. Hinge (Fig. 2) with left valve with 2 cardinal teeth, 2 posterior and 2 anterior lateral teeth; right valve with 2 cardinals, and single anterior and posterior laterals. Ligament relatively short, external. Shell colour white. Size: Up to 25 mm in length. Distribution: Endemic to Australia: Port Stephens, NSW, southwards and around southern Australia to North West Cape, WA. Habitat: Shallow subtidal seagrass and down to 200 m. Uncommon as beach washup. Comparison: This species has commarginal and radial sculpture, but the radial sculpture is weaker than in C. bella and C. tatei. Synonymy: Talocodakia kennethi Iredale, 1936 is a previously recognised synonym and Codakia perobliqua Tate, 1892 may also be a synonym.
