Holotype: Firtion, 1952, pl.9, fig.1; lost according to Fauconnier and Pourtoy in Fauconnier and Masure (2004, p.517).

Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly (and now) Surculosphaeridium, fourthly Surculosphaeridium?. This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym. Age: Cenomanian.
