Diagnosis Test large, may exceed 18 mm in length, robustly fusiform, poles rounded to bluntly pointed, axis of coiling straight, elongate fusiform juvenarium of two to three low volutions that are closely coiled about the small spherical proloculus, followed by two or three rapidly enlarging whorls that may exceed 1.5 mm in height, septa in the juvenarium regularly and highly fluted, in later whorls the extremely irregular fluting to the tops of the chambers may produce a number of vesicular chamberlets in the height of a single chamber; wall thin, alveolar; small chomata present in the inner whorls, narrow tunnel with irregular path and increasing unevenly in width with growth, may be roofed by phrenothecalike layers. L. Permian (Sakmarian); Japan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
