Family PSEUDOSTAFFELLIDAE Putrya, 1956

Tests medium to large in size, subspherical, subquadratic and subglobular, sometimes compressed along the coiling axis, somewhat elongate, with a straight, slightly concave or rounded umbilical regions and the same peripheral edge; involute, less often evolute in the outer whorl; coiling is often symmetrical, less often with oscillation of the axis in the early stage of growth; septa numerous, straight, short; wall three-four layered with diaphanotheca; Chomata from short weak and moderate in the beginning to powerful and ribbon-like in outer whorls. The aperture is simple, basal. Pennsylvanian (Bashkirian-Kasimovian).

Remark: Hanostaffella Cheong, 1984 is thought to be a deformation stage of Neostaffella A. D. Miklukho-Maklay, 1959 and therefore a synonym of this latter genus as already analysed by Villa et al. (2022).
