From Fensome et al., 2019:
Nyktericysta dictyophora He Chengquan et al., 1992, p.184,190–191, pl.1, figs.1–9. Emendation: Mao Shaozhi et al., 1999, p.156, as Quantouendinium dictyophorum. Holotype: He Chengquan et al., 1992, pl.1, fig.1; Gao Ruiqi et al., 1992b, pl.1, fig.1; Gao Ruiqi et al., 1992c, pl.1, fig.8; Mao Shaozhi et al., 1999, pl.5, fig.2. Originally (and now) Nyktericysta, subsequently Quantouendinium. Taxonomic junior synonyms: Nyktericysta dictyophora subsp. circularis and Nyktericysta fusiformis, both according to Mao Shaozhi et al. (1999, p.156) — although He Chengquan et al. (2009, p.304) retained the two taxa as Quantouendinium dictyophorum subsp. circulare and
Quantouendinium fusiforme respectively, Fensome et al. (2016b, p.57) agreed with Mao Shaozhi et al. (1999) regarding the synonymy. Age: Albian.
