asperum (Maier, 1959, p.319, pl.33, fig.2) Davey and Williams, 1969, p.6. Emendation: Sarjeant, 1983, p.113–114, as Polysphaeridium asperum. Holotype: Maier, 1959, pl.33, fig.2. Originally Hystrichosphaeridium, subsequently Polysphaeridium?, thirdly Dapsilidinium, fourthly (and now) Polysphaeridium. Questionable assignment: Davey and Williams (1969, p.6) — however, Sarjeant (1983, p.113–114) retained this species in Polysphaeridium without question. This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.95), since these authors did not fully reference the basionym. Age: middle Miocene.
Parent: Polysphaeridium
