Description Test elongate fusiform, subcylindrical, subtriangular with pointed or blunted axes and ends; coiling is tight with an axis shift in the first whorl; wall in internal whorls three-layered with a non-permanent outer tectorium, in the outer whorl wall thin, poorly differentiated into tectum and homogeneous primatheca with inconsistent and weakly defined outer tectorium, sometimes wall with a translucent rudimentary diaphanotheca in the upper part of the primatheca, in the outer whorl. sometimes fine pores; septa in the beginning whorls from flat to wavy and slightly folded in the axes, in parts of the test, in subsequent whorls. The folding of the septa intensifies along the entire length; tall, narrow or rounded angular arches; chomata are absent or weakly expressed; axial, thickenings are constant, from moderate to highly developed; the aperture is usually narrow, sometimes poorly distinguishable, less often moderate; sometimes there are cuniculi in the outer whorls.
