Diagnosis
ReferenceDiagnosis
H. H. Dijkstra and R. N. Kilburn 2001Shell thick, height to 55 mm, but most adults 30–35 mm, elongate to suborbicular, nearly equivalve, equilateral, auricles small and subequal, umbonal angle ca. 85–95°. Both valves strongly convex to more compressed, with prominent radial plicae (3–5, usually 3) and smaller lateral ribs (2–3), both plicae and their intervals radial striated. Microsculpture of close-set commarginal lamellae. Auricles with several radial riblets (8–14) and microscopic commarginal lamellae. Hinge small and straight. Byssal fasciole absent, byssal notch narrow. Active ctenolium with a few small teeth (1–3) on suture, sometimes absent. Resilifer elongate, triangular. Auricular crura strongly developed, resilial teeth weak or absent. Inner surface slightly plicated. Colour variable, cream, yellow, orange or brown with lighter or darker markings, occasionally uniform in colour; RV paler than LV.
