Original description Diagnosis. Test large and medium-sized, elongated fusiform to subcylindrical. Winding denser in internal whorls than in external. Test extends along axis in first whorls, while whorl height increases gradually. Test wall in internal whorls thin, in adult whorls of moderate thickness (up to 90 μm). Septae thin, strongly folded. Folding high, pronouncedly irregular to relatively ordered. Arches rounded, often arranged in two tiers, thus forming characteristic laces. Sometimes septal folding occurs in aperture region. Axial deposits variously expressed: absent or rudimentary in some species, in others relatively thick, occupying several internal whorls. Aperture slitlike, narrow, somewhat wider in external whorls. Sometimes it is hardly discernible because of strong septal folding. Chomata small, rounded, present on proloculus. Pseudochomata weak, slender, hook-shaped.
Occurrence. Daixina sokensis Zone of the Gzhelian (Upper Carboniferous) through Schwagerina vulgaris-Schwagerina fusiformis Zone of the Asselian (Lower Permian) of northeastern European Russia: Mezen River basin, the Timan, the Pechora Fore-Urals, and the Central Urals. [details]
