Phacoid shell twice as broad as the medullary shell, with seven pores on the radius. Arms nearly square, about as large as the phacoid shell, with a strong pyramidal terminal spine at the distal end. Patagium complete, between every two arms triangular, with rectilinear parallel rows of chambers; it connects the end points of the arm radius in such a manner that the whole shell becomes a regular square.

Diameter of the phacoid shell 90µm, of the medullary shell 45µm; length of the arms 100µm, greatest breadth 80µm.
