Diagnosis Test free, flattened, microspheric stage peneropliform at first, later discoidal with as many as forty annular chambers, and up to 8 mm in diameter, megalospheric tests may be flabelliform or reniform to discoidal, of constant thickness equal to that of the proloculus, length up to 1.7 mm and breadth up to 2.1 mm, comprised of twenty to thirty chambers, with only a single plane of endoskeletal pillars; other megalospheric tests have an initial planispiral coil followed by an uncoiled rectilinear, cylindrical, or elliptical stage, up to 1.2 mm in length; wall agglutinated, microgranular calcareous, with imperforate epidermis, followed successively inward by a subepidermal network formed by beams and rafters, a zone with quadrangular chamberlets formed by the beams, an undivided zone termed the annular canal, and a zone of interseptal pillars; aperture terminal, multiple. M. Jurassic (Dogger); Italy: Sardinia; France; Iran; Madagascar. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
