Polystephanephorus paracalathus (Sarjeant, 1960a, p.143-144, pl.6, fig.4; text-fig.3b) Sarjeant, 1961b, p.1096.
EMENDATION: Stancliffe and Sarjeant, 1990, p.206, as Polystephanephorus paracalathus. TYPE: Holotype: Sarjeant, 1960a, pl.6, fig.4; text-fig.3b; Stancliffe and Sarjeant, 1990, pl.2, figs.2-3,5; text-fig.2. 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: Mid Callovian.
