Diagnosis Test robust, subcylindrical, fusiform or subglobose, poles broadly rounded, up to 6 mm in length, small proloculus and first one or two volutions coiled in a different plane than later whorls, septa crenulate, crests of the folds thickened by secondary deposits, especially adjacent to the tunnel, cuniculi developed in the outer volutions where folds of adjacent septa are in contact; wall of early whorls thin, rapidly thickening in later whorls, of tectum and prominent thick keriotheca, chomata and pseudochomata commonly present but axial fillings minor or absent. L. Permian (Sakmarian), (L. to M. Wolfcampian); USA: California, Nevada. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
