Palaeostomocystis Appendix A

PALAEOSTOMOCYSTIS Deflandre, 1937b, p.52.  Acritarch genus.  Taxonomic junior synonym: Cladopyxidium, by implication in Marheinecke (1992, p.105), who transferred the "type species", Palaeostomocystis reticulata, to Cladopyxidium — however, Lentin and Williams (1993, p.483) retained Cladopyxidium.  This name was not validly published in Deflandre (1935, p.234) since no type was designated.  According to Stover and Evitt (1978, p.6), Deflandre (1966, p.6) emended the diagnosis of this genus; however, no formal emendation was proposed in Deflandre (1966).  Type: Deflandre, 1937b, pl.12 (al. pl.9), fig.4, as Palaeostomocystis reticulata.
