Description Emended diagnosis: Test uniseriate subcylindrical slightly curved. Proloculus not prominent followed by a series of pseudochambers without sutures and more or less developed pseudosepta. External surface of the test is smooth and not constricted opposite internal wall thickenings (unique difference with Vervilleina). Wall structure is two-layered as in Syzrania with a thin inner, dark microgranular, ancestral layer, and an external, hyaline, evolved, fibrous layer. Aperture terminal, areal, simple.
Occurrence: FAD in upper or uppermost Gzhelian (Afghanistan, Russia, Canadian Arctic, Carnic Alps, Darvaz; northern Iran). The acme seems to be Asselian–Sakmarian (Donbass (Ukraine); Perm area and Bashkortostan (Russia); Tezak (Afghanistan); Darvaz; Bolivia; Barents Sea, Canadian Arctic, Greenland; and New Mexico). Rare and/ or doubtful in the other Permian stages of Russia (Urals, Pechora and Primorye); where these questionable representatives might belong to Biparietata Zolotov a in Zolotova & Baryshnikov , 1980, which is likely a homeomorphous genus with a different wall microstructure.

Diagnosis Test small, elongate, about 0.5 mm in length, ovate proloculus followed by tubular stage with slight constrictions or pseudosepta resulting in narrow and elongate pseudochambers; wall calcareous, thick, hyaline, fibrous, finely perforate; aperture terminal. L. Permian (Asselian to Sakmarian); USSR: Donbass, Bashkir; Afghanistan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
