From Fensome et al., 2019:
Stromaphora ovata Xu Jinli et al., 1997, p.124, pl.8, figs.1–2,5–8; pl.23, fig.15 ex He Chengquan et al., 2009, p.372,672. Holotype: Xu Jinli et al., 1997, pl.8, fig.1. This name was not validly published in Xu Jinli et al. (1997), since no English or Latin description was provided; He Chengquan et al. (2009, p.672) validated the name by publishing an English diagnosis. Age: Middle–Late Eocene.
