Membranilarnax
MEMBRANILARNAX Wetzel, 1933b, p.51. Emendation: Sarjeant, 1985b, p.149,151–152. Taxonomic junior synonym: Membranilarnacia, by implication in Downie and Sarjeant (1965, p.130) who questionably transferred the "type species" of Membranilarnax, Membranilarnax pterospermoides, to Membranilarnacia — however, Lentin and Williams (1973, p.93) retained Membranilarnacia. Stover and Evitt (1978, p.295) considered Membranilarnax to be an acritarch genus. Sarjeant (1985b, p.149,151–152) considered Membranilarnax to be a skolochorate dinoflagellate cyst. This name was not validly published in Wetzel (1932, p.136), since that author did not provide a description or designate a type, the latter being a requirement at that time under the I.C.Z.N. Type: Wetzel, 1933b, pl.6, fig.2, as Membranilarnax pterospermoides.
