Description Revised diagnosis. Small, elongate fusiform to cylindrical schwagerinid genus with relatively small proloculus, and compactly coiled inner volutions and outer relatively loosely coiled ones. Wall thin and consist of a tectum and lower less dense layer in the inner volutions and of a tectum and fine keriotheca in the outer ones. Septa thin and weakly fluted in the axial regions. Weak axial fillings observed only in the inner volutions. Low chomata present throughout growth. Distribution and age. Panthalassan mid-oceanic seamounts (Shiraiwa, Yayamadake, and probably Akiyoshi limestones, SW Japan); Indochina (Vietnam). Late Gzhelian to early (earliest?) Permian. (Ueno (2022)). [details]

[details] Diagnosis Test small, elongate fusiform, axis of coiling straight, septa numerous, straight and unfluted in the central part of the test but may be fluted toward the poles; wall of two layers, a tectum and less dense lower layer or keriotheca, tunnel single, chomata poorly developed, axial fillings restricted to the polar regions of the early whorls but more extensive in later whorls.
