Description Emendation: Description: Test spherical, rarely ovoid, involute, with rounded periphery and without umbilicus. Streptospirally coiled with the last few volutions rarely aligned. Spherical proloculus followed by an enrolled pseudoseptate second chamber gradually and proportionally increasing in size, but more tight in the early whorls forming a juvenarium. Periphery margin broadly rounded. Two groups of specimens may be considered as megalospheric and microspheric generations. Wall calcareous porcelaneous, well preserved in our material. Aperture simple at the end of the tubular chamber. Occurrence: Moscovian–Late Pennsylvanian of Russia. Early Permian; probably cosmopolitan. Middle-Late Permian of Paleotethys and Neotethys (Tunisia, Croatia, Serbia, Hungary, Greece, Italy, Turkey, Iran, Himalaya, South China, Sumatra, and Malaysia). (Krainer et al. (2019)).

Original description Rounded to ovoid test, moderately large in diameter, with relatively numerous volutions. No pseudosepta. Proloculus spherical with flexostyle canal. Wall particularly thin and often recrystallized (light gray to whitish color). Occurrence. Early Permian of Bashkorotostan (Russia), South China and the Carnic Alps. Artinskian of South America (Yaurichambi, Bolivia). Late? Kungurian (latest Leonardian) of New Mexico. Bolorian (late Kungurian) of Darvaz (Tajikistan) and Armenia. Lazarus effect or parallel evolution with the group Glomospira tenuifistula Ho, 1959 during the Triassic. (Vachard et al. (2015)). [details]
