( Mediodia et al. 2017): With a smooth and shiny symmetrical shell and has predominantly dark brown to black colour with wavy dark pattern. Sculpture of fine concentric semi-circular rings (Fig. 8 d). It has two similar-shaped valves joined by a hinge without teeth at the anterior portion. It has two muscle scars, the large posterior adductor muscle scar and the greatly reduced anterior adductor muscle. The byssal and pedal retractor muscle scar is located below the adductor muscle forming a thick straight line moving towards the middle portion of the shell. The pallial line was seen as a curved line towards the adductor scar.
