Description Test with an Endothyra initial stage, and a last whorl enlarging rapidly and tending to uncoil. Wall microgranular to coarsely granular. Aperture simple, becoming cribrate in the last
chambers.
Occurrence: Latest Visean of Donets Basin (limestones B4 and B6; Vdovenko, 2001: tab. 1, p. 172), Morocco and Montagne Noire. ?Late Visean of Japan. Visean/Serpukhovian boundary of Iowa (USA). ?Early Serpukhovian of Kazakhstan (as Mikhailovella? sp.; Brenckle and Milkina, 2003: pl. 5, fig. 20). Late Serpukhovian (Protvian) of Donets Basin and middle and southern Urals. Zapaltyubian of the Urals. Ichinotani Fm. of Japan.

Description Diagnosis: Medium sized, endothyroid skew coiled with the last chamber tending to be uncoiled. Supplementary deposits as crustae. Aperture simple terminal, then areal and finally cribrate.
Occurrence: ?MFZ12 of South China, Early Brigantian-late Serpukhovian; for this moment, only known in western Palaeotethys and Japan. Early Brigantian in southern France (Pille, 2008), late Visean of Japan (Ueno & Nakazawa, 1993), late Visean-early Serpukhovian of Donbass (Vdovenko, 2001).

Diagnosis Test with early stage streptospirally coiled and whorl increasing slowly in height, final whorl enlarging more rapidly and may tend to uncoil, last chamber occupying up to one-half the test diameter, septa straight and radial; wall calcareous, microgranular to coarsely granular, secondary deposits variable, may be massive against the chamber floors; aperture basal and simple in the early stage, that of the final chamber areal and multiple. L. Carboniferous (U. Serpukhovian); USSR: Donets basin. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
