Diagnosis Test small, up to 2.4 mm in length, fusiform, with bluntly pointed extremities, small to average-sized proloculus followed by about six to seven volutions in a closely and streptospirally coiled ovoid juvenarium, later whorls with changed axis of coiling that lengthens rapidly, septa slightly undulating in the central region and slightly fluted toward the apices; wall thin, three layered, of tectum, relatively dense diaphanotheca, and outer tectorium and rarely may have a suggestion of a thin lower tectorium, chomata well developed in all but final whorl, asymmetrical, about half the height of the chamber, tending to overhang the tunnel that is developed after the coiling axis straightens and elongates, secondary deposits gradually thinning toward the apices and may grade into the axial filling, or the latter may be present only in the apical areas and absent from the axial region. U. Carboniferous (Moscovian), L. Desmoinesian; USA: New Mexico; Mexico. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
