Original description: [Cookson and Eisenack, 1970, p.146]:

Description:
Shell rather flat, almost circular to slightly angular in outline, with a slight apical prominence and with, as in the holotype, or without a slight antapical concavity bounded by blunt or pointed outgrowths. In one example (from 1486-1523 ft) a girdle is clearly evident on the ventral surface. The shell opens by the removal of a considerable portion of the epitheca. The ornamentation consists of densely arranged, irregularly outlined thickenings, some of which narrow to short, hair-like appendages (Pl. 13, fig. 4).

Dimensions:
Holotype: c. 102 µm long, 90 µm broad.
Range in breadth: c. 78-94 µm.
