Originally Granoreticella (name not validly published), subsequently (and now) Pyxidinopsis. 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.661) validated the name by publishing an English diagnosis. Age: Oligocene.
