Original description: Shell subcylindrical or elongate ellipsoidal, approximately twice as long as broad. An inner, densely spongy core is surrounded by a narrow mantle of less dense meshwork. Entire surface usually sparsely covered with bristle-like spines, which in many specimens tend to be longer at the two poles of the main axis. At one pole is a pylome, usually surrounded by short, irregular teeth.

(based on 29 specimens) Length 150-255 µm, breadth 78-125 µm. Length of surface spines 5-40 µm (usually broken off). Distinguishing characters (rw): his species differs from all others of the genus in the presence of a pylome
