Loxoconcha ex. gr. petasa ssp. 1

Fig. 30 a-d

Description. The shape of this subspecies resembles the outline of L. petasa . The ornamentation consists of polygonal meshes that vary in size but generally become finer towards the anterior-and posterior margins. In the postero-ventral area of the valve one more or less pronounced tubercle is present and covered in polygonal meshes. From the internal view it can be seen that the tubercle is hollow. The hinge and muscle scar are genus typical. Dimension: L = 0,58 – 0,66 mm, H = 0,33 – 0,41 mm, the minimum sizes include juveniles too.
