Pterocystidiopsis Appendix A

PTEROCYSTIDIOPSIS Deflandre, 1937b, p.90.  Acritarch genus.  Taxonomic junior synonym: Caddasphaera, by implication in Courtinat in Courtinat and Gaillard (1980, p.80), who transferred the "type species" of Caddasphaera, Caddasphaera halosa, to Pterocystidiopsis — however, Lentin and Williams (1981, p.31,237) retained Caddasphaera.  This name was not validly published in Deflandre (1935, p.234) since no description was given.  Type: Deflandre, 1937b, pl.17 (al. pl.14), figs.7–8, as Pterocystidiopsis stephaniana.
