Original Description

Bilobed cephalis of the usual acanthodesmiid form, its outline marked by an almost complete frontal ring. Anterior and posterior faces of this cephalic shell very delicate, with small subcircular pores. In the frontal plane, surrounding the cephalic shell, is a more robustly developed zone of chambered structure, which may be kidney-shaped, elliptical or circular in outline. The cephalic cavity is generally about a third to a half as wide as the total width of the skeleton.

Size:
(Based on 9 specimens) Width of cephalic cavity 130 to 170µm; height of sagittal ring 65 to 80µm; greatest diameter of total skeleton 205 to 365µm.
