Diagnosis Test planispiral and involute, somewhat compressed but with rounded to subacute periphery; wall agglutinated, outer layer imperforate and subepidermal layer uniformly alveolar, septal structure differentiated from remainder of wall, in later stage the lower part of the septa coalesce as an imperforate basal layer against the previous whorl, in median section appearing very short (hence originally termed semisepta) because of the high median aperture; aperture an elongate slit, extending up from the base of the apertural face for nearly its total height. L. to U. Cretaceous (Aptian to Cenomanian); Algeria; Qatar, Persian Gulf. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
