Membranilarnax formosa
Membranilarnax formosa Tasch, 1964
Originally Membranilarnax, subsequently Membranilarnacia?.
Tax. jr. synonym of Schizosporis reticulata Cookson and Dettmann, 1959, according to Pierce, 1976.
Holotype: Tasch, 1964, pl.1, fig.23
Locus typicus: Clark County, Kansas, U.S.A.
Stratum typicum: Albian
Original diagnosis: Tasch, 1964, p.192
Irregularly subovate shell, tapered apically and bearing a network of polygons on inner capsule; thin, short, tubular processes joined by fine membrane forming fringe to inner capsule; processes projecting from polygon corners.
