Description Emended diagnosis: Endothyroid test with semi-evolute last whorls. Chambers are globular and well sutured. Supplementary deposits as crusts, tubercules and/or broad spines. Wall microgranular with a thin dark tectum and a differentiated clearer thicker inner layer; i.e. more similar to an Omphalotis wall than to an Endothyra wall.
Occurrence: Serpukhovian-early Moscovian of Russia (Bashkortostan, southern Urals, Taymyr, Siberia), Ukraine (Donets Basin), Spain, Austria, Algeria (Lys, 1985), northern Iran, Austria, South China (Zhao et al., 1984). Asbian?-Serpukhovian of England (Fewtrell et al., 1989). Latest Venevian-Zapaltjubian of northern Spain (Cózar et al., 2016a, 2018). Latest Venevian-early Serpukhovian of southern France (Montagne Noire: Vachard, 1977; Pille, 2008; Vachard et al., 2016, 2018b). Serpukhovian of the USA (Zeller, 1953; Brenckle, 1973; Rich, 1980, 1982, 1986). Biozones 2 (Mikhailovian) and 11 (Asatauian?) of Akiyoshi area.
