Diagnosis Test large, up to 7 mm in length, ellipsoidal, poles broadly rounded, adult tests with about thirteen whorls, septa increasing from about eight per whorl in the early stage to thirty in the outer whorl, septa nearly plane in their upper part, widely spaced fluting at the base of the septa throughout the length of the test, locally forming cuniculi; wall of early whorls thin, later thicker, of tectum and thick, coarsely alveolar keriotheca that extends along the septa to result in a wedgelike form, tunnel wide and well developed, bordered by low, narrow, and asymmetrical chomata in the inner four to five whorls, later discontinuous, outer whorls with prominent secondary deposits on both faces of the septa as well as the inner surface of the chambers from the tunnel to the poles, axial fillings present in the early whorls. M. Permian (Kungurian); Japan; USA: California, Oregon. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
