It is very difficult to find the atrial spicules, likely the atrial areas are represented by small spots on the intersections of the main skeletal beams composed of fused and unfused diactins from the atrial surface, which contain few pentactins and stauractins. The observed variations in microsclere content and dimensions do not notably differ from previous descriptions of representatives of this species.
