Description. Poorly developed glomospiral initial stage followed by an uncoiled tubular last part arranged symetrically around the initial coiling (D = 0.67 mm; w = 0.29 mm). No umbilicus. Four whorls. Lateral sides of spire flat to slightly inflated. Peripheral margin rounded. Uncoiling in form of a tubular chamber in which the diameter is equal to the height of the last planispiral whorl (h = 0.10 mm), erect, vertical, tubular, aligned with the axis of coiling. No secondary incrustation of lateral walls. Wall originally porcelaneous, currently neosparitized (s = 0.01 mm).
Occurrence. Late Pennsylvanian of Texas and Ecuador. Early Permian of Australia. Middle Permian of Cambodia. Early?-middle? Kungurian of New Mexico (Yeso Group: sample MG 10-20a. San Andres Fm: sample MLY(2) 5a-24).
