Description Test shortly fusiform to fusiform, often asymmetrical. Early stage discoidal, deviated in comparison with the later stage more or less fusiform, with acute poles. Septa numerous, unfluted in the center of the chambers but slightly fluted at the poles, especially in the outer whorls. Chomata low, asymmetrical and bordering a broad and low tunnel ; occasional strong and ribbon-shaped. Wall bilayered with an outer tectum and a protheca. Primitive forms (Schubertina or Eoschubertella of the authors) exhibit only the dark tectum; advanced forms (Dutkevitchites, Oketaella and Biwaella) exhibit, in the wall, the tectum and an inner porous layer. Aperture terminal simple.
Occurrence: Bashkirian–early Moscovian forms belong more probably to the genus Schubertina (or Eoschubertella of the authors), whereas typical representatives are distributed from late Moscovian (only early Virgilian in North America: Sanderson et al., 2001) to latest Permian. Schubertella
is cosmopolitan and distributed globally between the paleotropics, from the Moscovian to the Wordian (Rauzer-Chernousova et al., 1951; Skinner & Wilde, 1966a, b; Leven, 1998a, b; Davydov , 2011); then, it is only Paleotethyan. [details]

Diagnosis Test fusiform to subcylindrical, advanced taxa may be uncoiled and rectilinear or flaring in later stage; early coiling streptospiral or with sharp change in direction from early whorls to later ones; early septa flat, fluted in advanced taxa; wall varied, with tectum and upper and lower tectoria, tectum, and diaphanotheca, tectum and lower tectorium only, a single thin layer, or with tectum and alveolar keriotheca; tunnel single, chomata low to large and asymmetrical. U. Carboniferous (Moscovian) to U. Permian. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
