Genus Nematosphaeropsis

Nematosphaeropsis Deflandre and Cookson, 1955, p.268.

EMENDATIONS: Williams and Downie, 1966c, p.222; Wrenn, 1988, p.137.

SYNONYM(S): Taxonomic junior synonyms: Trabeculidium, according to Stover and Williams (1987, p.217) - however, Sarjeant (1989, p.93) retained Trabeculidium; Pterococcus Lohmann (an illegitimate name) and Coccopterus, by implication in Reid (1974, p.592) and Fensome et al. (1993b, p.93), who included the "type species", Pterococcus (subsequently Coccopterum) labyrinthus, in Nematosphaeropsis.

COMMENTS: This name was not validly published in Deflandre and Cookson (1954, p.1237), since these authors did not provided a description.

TYPE: Deflandre and Cookson, 1955, pl.8, fig.5, as Nematosphaeropsis balcombiana.
