Anterior margin oval, inflated; dorsal margin curved downwards; ventral margin slightly rounded or nearly straight; posterior margin obliquely arc-shaped. Umbo inflated, above hinge line, located at 1/3 of the dorsal margin, and often eroded. Periostracum orangish to brownish, with straight broken blackish-green rays and thin growth lines. Growth lines arranged in irregular concentric circles. Zigzag sculpture presented on all over the shell surface but weakening from umbo to edge. Hinge short. Ligament short and strong. Mantle muscle scars obvious. Anterior adductor muscle scars oval, deep, smooth in junior but rough in adult; posterior adductor muscle scars long oval, smooth. Left valve with two pseudocardinal teeth, equal height, anterior tooth small and flat, posterior tooth thick and pyramidal; anterior pseudocardinal tooth of the right valve well developed, posterior pseudocardinal tooth reduced, connected to lateral teeth. Lateral teeth of both valves long and thick. Nacre white or light orangish.

has been seriously underestimated for a long time due to the common misidentification of museum material. Upon examination of museum specimens, it has been discovered that specimen NZMC10542 in the National Zoological Museum of China and specimens 15_NCU_XPWU_AA01-11 in Nanchang University were actually
