Original Description
Subellipsoidal shell, of which the thorax forms the major part. Cephalis spherical, usually pore-less. half or more of it sunken into the thorax, with a small apical horn. Collar stricture generally not pronounced externally. From the base of the cephalis, primary lateral and dorsal spines extend in the thoracic wall or within the thoracic cavity to join the inner surface of the upper wall. Remainder of shell subellipsoidal. with subregular pores not arranged in rows, and with practically no tendency to form a spongy meshwork. In some specimens. a line in the shell wall (with no change in contour) distally separates a short, flattened area. which may be regarded as an abdomen, from the remainder, which may be regarded as the thorax.

Size: (Based on 35 specimens) Total length 95-150µm. Maximum breadth 75-130µm.

Etymology: From the Greek neoteros = younger.
