Diagnosis Test subtriangular in outline, elongate, and strongly compressed, periphery truncate and angles sharp to carinate, globular to fusiform proloculus followed by broad and low chambers, at first in slightly arcuate series, later with straight dorsal margin and slightly lobulate ventral one, sutures weakly depressed, flush or slightly elevated, gently arched, extending farther distally on the dorsal margin and curving back proximally to the ventral margin where the sutures are slightly constricted; wall calcareous, hyaline, perforate, radial in structure, surface of the flat sides smooth and unornamented other than the possibly elevated sutures; aperture at the dorsal angle, produced on a short neck, and bordered with a thickened rim, may be rounded or have a crenulate margin as in an incipient radiate aperture. L. Jurassic (Pliensbachian) to U. Cretaceous (Cenomanian); cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
