Diagnosis Test attached, concavoconvex, early chambers in a low trochospiral coil, increasing rapidly in breadth as added and nearly astacoline in appearance, but early part may be obscured by secondary thickening, then abruptly changing to very broad, low, crescentic, and strongly overlapping chambers, separated by flush and strongly oblique sutures as seen from the spiral side, amount of overlap increasing until the chambers become cyclical, final chamber may occupy much of the umbilical side, each chamber has an umbilical apertural extension on the umbilical side, those of successive chambers overlapping, sutures strongly curved, weakly depressed, periphery acutely angular and carinate; wall calcareous, with widely spaced coarse perforations except for the imperforate peripheral carina and umbilical apertural flap; aperture interiomarginal, opening beneath the umbilical flap. L. Cretaceous (Berriasian) to M. Miocene (U. Tortonian); Sweden; Germany; USA: California; USSR: Ukraine, Crimea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
