Margosphaera Nagy 1965, p. 208 nom. rej. Taxonomic synonym: Selenopemphix; Fensome et al. (2016a,
p.636) proposed the conservation, now approved, of Selenopemphix Benedek, 1972 against Margosphaera Nagy,
1965. The possible synonymy of Selenopemphix and Margosphaera was first mooted by Head (1993, p.32). Type:
Nagy, 1965, pl.5, figs.23–25, text-fig.7, as Margosphaera velata.
