Diagnosis Test large, up to 15 mm in length, elongate fusiform, with acuminate poles, axis of coiling straight, large proloculus followed by about eight loosely coiled whorls, septa fluted throughout, most strongly at the base of the septa and toward the poles and may be sufficiently strongly folded to produce closed chamberlets, thin dense partitions or phrenothecae may cross the chambers between folds of the septa; wall thick, of tectum and coarsely alveolar keriotheca, axial fillings may be thin and confined to the poles, or even absent in some species, chomata distinct in early taxa, but less prominent in later ones, tunnel straight. L. Permian (Asselian-Sakmarian to Artinskian), Wolfcampian to Leonardian, to M. Permian (Kungurian); North America; Europe; Asia.
