From Fensome et al., 2019:
Manumiella delicata (Balteş, 1969, p.34, pl.1, fig.7 ex Lentin and Williams, 1973, p.40) Bujak and Davies, 1983, p.161. Holotype: Balteş, 1969, pl.1, fig.7, designated by Lentin and Williams (1973, p.40). Originally Deflandrea, subsequently Isabelia (combination illegitimate), thirdly Isabelidinium, fourthly (and now) Manumiella. This name was not validly published in Balteş (1969, p.34) since that author considered it to be provisional. Age: Early Eocene.
