?pirus (Deunff, 1959, p.35–36, pl.10, figs.90–93) Downie and Sarjeant, 1965, p.130. Holotype: Deunff, 1959, pl.10, fig.93. Originally Membranilarnax?, subsequently (and now) Membranilarnacia?. Questionable assignment: Downie and Sarjeant (1965, p.130); and Lachkar and Masure in Fauconnier and Masure (2004, p.389) as a problematic species. This species probably represents acritarchs. N.I.A.
