*Polystephanephorus calathus (Sarjeant, 1961a, p.104, pl.14, fig.7; text-fig.7) Sarjeant, 1961b, p.1096.
EMENDATION: Stancliffe and Sarjeant, 1990, p.205, as Polystephanephorus calathus. TYPE: Holotype: Sarjeant, 1961a, pl.14, fig.7; text-fig.7; Stancliffe and Sarjeant, 1990, pl.2, figs.1,4; text-fig.1. HISTORY: Originally Polystephanosphaera, subsequently (and now) Polystephanephorus, thirdly Hystrichosphaerina. Lentin and Williams (1981, p.232) retained this species in Polystephanephorus. COMMENTS: Although Sarjeant (1961b, p.1096) did not fully reference the basionym when he proposed this combination, he was clearly using zoological nomenclature, which does not require basionym citations. AGE: Early Oxfordian.
