Original description Diagnosis: Mature test is exceptionally large for a schubertellid. Juvenarium exhibits “endothyroid” or skewed initial growth stages characteristic of the Schubertellidae. Axis of coiling rotates to become typically fusiform beyond the first two volutions. Differs from Schubertella Staff and Wedekind 1910 and Biwaella Morikawa and Isomi 1960 in its large size for a schubertellid, greater number of volutions, and fluted septa. Resembles the near-contemporaneous Paleo-Tethyan genus Dutkevichites Davydov 1984, but also differs in its larger size, more fusiform shape, greater number of volutions, more uniform coiling, more intensely fluted septa, and higher degree of rugosity in the spirotheca. The juvenaria of some specimens resemble mature Fusiella schubertellinoides Suleimanov 1949. Closely resembles Schwageriniformis in general test morphology, but species of Schwageriniformis have a “schwagerinid” spirotheca and lack the skewed initial chambers of schubertellids.
Occurrence: Upper part of the Virgilian Stage. Nevada.
