Spiniferites? hirundo (Eisenack, 1958a, p.404–405, pl.24, fig.12) Sarjeant, 1981, p.123. Emendation: Sarjeant, 1985a, p.76–77, as Achomosphaera hirundo.

Now Cordosphaeridium?. Originally Hystrichosphaeridium, subsequently Achomosphaera, thirdly Lanternosphaeridium, fourthly (and now) Cordosphaeridium?, fifthly Spiniferites?.
At the time of the transfer, Sarjeant, 1985, questionably included this species in Spiniferites.
Lentin and Williams, 1989, questionably retained this species in Cordosphaeridium.
