Batiacasphaera bellula

?bellula (Jiabo, 1978, p.51, pl.23, figs.14–16) Jan du Chêne et al., 1985a, p.15.  Holotype: Jiabo, 1978, pl.23, fig.15.  Originally Tenua Eisenack, subsequently Kallosphaeridium?, thirdly Batiacasphaera, fourthly (and now) Batiacasphaera?, fifthly Sentusidinium.  Questionable assignment: Marheinecke (1992, p.76).  In transferring this species to Sentusidinium, Xu Jinli et al. (1997, p.46) did not discuss the full history of this taxon; we therefore prefer to retain it questionably in Batiacasphaera.  Age: Early Tertiary.

Parent: Batiacasphaera
