Duosphaeridium nudum

*nudum (Cookson, 1965a, p.87, pl.10, figs.1–4) Loeblich Jr. and Loeblich III, 1968, p.211.  Holotype: Cookson, 1965a, pl.10, fig.1.  Originally Diphyes, subsequently (and now) Duosphaeridium.  This combination was not validly published by Davey and Williams (1966b, p.97), since these authors did not fully reference the basionym.  Age: late Eocene.
