Description Description: Tetrataxid genus with low conical and large tests, with many whorls, and large and depressed umbilicus, and without depressed sutures. Wall microstructure and apertures similar to those of Tetrataxis.
Occurrence: Bashkirian (Groves, 1983)–Capitanian (Ciarapica et al., 1986); probably cosmopolitan. Wuchiapingian of Japan (Kobayashi, 2013).

Diagnosis Test large, up to 2.25 mm in diameter, low and conical, early stage as in Tetrataxis, up to six chambers in the earliest whorl, later with low, crescentic chambers, gradually decreasing to four per whorl, forming many whorls and a spreading test; wall calcareous, microgranular, outer granular layer and inner hyaline fibrous layer; aperture umbilical in position, a narrow opening beneath a valvelike flap from the inner margin of the final chamber, those of earlier chambers and earlier whorls also may remain open. U. Carboniferous (Moscovian); USA: Texas, Oklahoma; Austria; Algeria. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
