From Fensome et al., 2019:
Cangxianella granospinosa Pan Zhaoren in Xu Jinli et al., 1997, p.113, pl.40, fig.10 ex He Chengquan et al., 2009, p.382–
383,651. Holotype: Xu Jinli et al., 1997, pl.40, fig.10. The name was not validly published in Xu Jinli et al. (1997),
since no English or a Latin description was provided; He Chengquan et al. (2009, p.651) validated the name by
publishing an English diagnosis. Age: Oligocene.
