Diagnosis Testlarge,elongate, upto 10.5mminlength, ellipsoidal to subcylindrical, slightly inflated in the median plane, poles broadly rounded, small globular proloculus followed by sixteen or more slowly enlarging whorls, septa thin, closely spaced, up to about thirty-three per whorl, flat and unfluted, directed slightly forward at the base; wall of earliest whorls with tectum and less dense lower layer, later whorls with tectum, thick diaphanotheca or keriotheca, and thick inner and outer tectoria, numerous small parachomata extend about half the chamber height but almost reach the top of the chamber adjacent to the septa; foramina small, circular in early whorls, later elliptical, up to about thirty-four in the later whorls. U. Permian (U. Kazanian to L. Tatarian); Japan; S. China; Cambodia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
