Original Description

A shell with a well-developed cephalis. Apical spine not developed. Shell thick-walled. Sagittal ring slightly protruding on to the outer surface on cephalis. Cephalis pores of different size, commonly arranged symmetrically relative to the sagittal ring. Diameter of large pores about 20 μm; that of small ones, 8-11 μm. Dimensions of cephalis: length, 55-80 μm; width, 75-100 μm (based on measurements of 20 specimens). Commonly about 6 basal feet. They are connected by transverse bars and form something similar to a thorax with large pores and smaller fine bars. Single pores are visible in places of their junction. When there are 6 basal feet, they form a hexahedron in the section. The diameter of pores is 40-45 μm; thickness of bars, 10-15 μm. Width of pseudothorax 100-110 μm; the preserved length 50-60 μm.

Etymology:
This form was first discovered by paleontologist H. Ling, and is named lingi after him.
