From Fensome et al., 2019:
Nyktericysta "microreticulata" He Chengquan et al., 1992, p.185–186,192, pl.1, figs.10–15. Emendation: Mao Shaozhi et al., 1999, p.157, as Quantouendinium microreticulatum. Holotype: He Chengquan et al., 1992, pl.1, fig.10; Gao Ruiqi et al., 1992b, pl.3, fig.1. Originally (and now) Nyktericysta, subsequently Quantouendinium. Taxonomic junior synonyms: Nyktericysta microreticulata subsp. circularis and Nyktericysta symmetrica, both according to Mao Shaozhi et al. (1999, p.156) — although He Chengquan et al. (2009, p.305–306) retained the two taxa as Quantouendinium microreticulata subsp. circulare and Quantouendinium symmetricum respectively, Fensome et al. (2016, p.57) agreed with Mao Shaozhi et al. (1999) in treating Nykterocysta microreticulata subsp. circularis as a synonym of Nyktericysta microreticulata. Age: Albian.
