From Fensome et al., 2019:
Batiacasphaera retirugosa Xu Jinli et al., 1997, p.48–49, pl.42, fig.3 ex He Chengquan et al., 2009, p.649. Holotype: Xu Jinli et al., 1997, pl.42, fig.3. Originally Pseudobohaidina (name not validly published), subsequently (and now)
Batiacasphaera. Taxonomic junior synonym: Batiacasphaera oblongata, according to Wood et al. (2016, p.69).
The name Pseudobohaidina retirugosa was not validly published in Xu Jinli et al. (1997), since no English or Latin
description was provided; He Chengquan et al. (2009, p.649) validated the name by publishing an English diagnosis
on proposing the transfer to Batiacasphaera. Age: Middle–Late Eocene.
