Original description Shell of median size, irregularly elongate-fusiform, silicule-shaped, with acutely pointed poles. Axis of coiling gently incurved. Mature shell consisting of 4-6 volutions. Length 3.61-5.70mm; width 0.93-1.79mm. Axial ratio 2.64-3.57mm. Spirotheca thin and meager, composed of a single-layered pro-theca, with mural micropores in the outer whorls. Septa nearly plane, sometimes slightly folded at the lateral slopes, but more strongly folded toward the polar regions. Chomata well developed, of various shapes. Tunnel narrow and low. Proloculus minute.
Remarks The new genus is similar to Verella Dalmatskaya, 1951 in its spiro-theca, but differs from the latter in its larger size, numerous whorls, conspicu-ous chomata, and absence of axial filling. It resembles Eofusulina Rauser, 1951 most closely in the structure of the spirotheca, but can be distinguished from the latter by its numerous whorls, tightly coiled volutions, marked chomata, weakly folded septa, small proloculus and absence of axial filling.
