Shell flat, broadly oval in outline, divided almost equally by a rather broad shallow girdle and narrowing towards a short blunt apical projection and one or occasionally two slight antapical prominences. A short, broad longitudinal furrow is developed on the central surface of the hypotheca. The capsule is approximately circular in outline and does not fill the shell laterally. A pylome has not been observed. Shell-membrane thin, transparent, wall of capsule slightly granular.
Dimensions: Type 57 µm long, 48 µm broad. Range 53-67 µm long, 43-52 µm broad.
