Diagnosis Test discoidal to convexoconcave, very thin, only about 1 mm thick, megalospheric individuals 8 mm to 10 mm in diameter and one microspheric individual more than 23 mm in diameter, megalospheric embryo with a large central chamber having many short exoskeletal beams of two orders on the upper surface that result in an alveolar layer, central chamber also surrounded laterally and below by a periembryonic zone with numerous beams near the upper surface forming an alveolar layer at the sides of the central chamber, and a layer of relatively large and undivided irregular chambers below the proloculus; postembryonal chambers subdivided into a marginal zone with alveolar structure produced by the vertical radial beams, a radial zone with welldeveloped beams of triangular section that alternate in position from one chamber to the next, and a central zone in which the beams probably anastomose, although detailed structure is obscured by the coarse agglutinated material; apertural pores lead obliquely from one chamber to the next. L. Cretaceous (U. Aptian to ?Albian); India; Afghanistan; Tibet. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
