From Fensome et al., 2019:
Amphorulacysta ruvuense, (Msaky, 2011a) comb. nov.
Holotype: Msaky, 2011a, pl.1, fig. 5.
Originally Amphorula (generic name illegitimate), subsequently (and now) Amphorulacysta.
The combination Amphorulacysta ruvuense is proposed here because the generic name Amphorula Dodekova is illegitimate.
Age: Oxfordian (from cuttings) and Tithonian.
