Amphorulacysta delicata

delicata (van Helden, 1986, p.188, pl.4, figs.4–7) Williams and Fensome 2016, p.139. Holotype: van Helden, 1986, pl.4, fig.4. Originally Amphorula (generic name illegitimate), subsequently (and now) Amphorulacysta. This combination was not validly published in Chen (2013, p.295), since that author did not fully reference the basionym. Age: Portlandian–early Berriasian.
