1977 Cibicidoides (?) simplex McCulloch : p. 447, pl. 152, fig. 12.

Remarks. This species is characterised by its biconvex text with a bluntly angled periphery, a prominently perforated wall and sutures which are flush to only slightly depressed. The specimens in this study are smaller than the type specimen described by McCulloch (1977).
