From Fensome et al., 2019:
Andalusiella rhomboides, (Boltenhagen, 1977, p.106–107, pl.20, figs.1a–b,2a–b,3) Lentin and Williams, 1980, p.41.
Emendation: Masure et al., 1996, p.182, as Andalusiella rhomboides.
Holotype: Boltenhagen, 1977, pl.20, figs.1a–b.
Originally Svalbardella, subsequently (and now) Andalusiella.
Age: Campanian.

Emended diagnosis:

Masure, Tea and Yao 1996, p. 182:

Diagnosis:
Proximate, acrocavate or cornucavate dinoflagellate cyst with rhomboidal to ovoidal central body, one apical horn and only one antapical horn. Wall composed of a verrucose periphragm and verrucose endophragm. The periphragm on distal end of horns may be verrucose or smooth. Brown or colorless endophragm.
Peridinoid paratabulation indicated by the archeopyle, paracingulum slightly descending (Evitt, 1985), levorotatory bordered by folds and continuous verruca, parasulcus with bean-shaped flagellar scar.
Intercalary archeopyle of I/I type, standard 2a hexa, isodeltaforme, operculum free, occasionally adherent.

Remark:
Svalbardella sp. A, sp. B and sp. D are considered as specimens of the population of Svalbardella rhomboides. These specimens have ovoidal central bodies and longer apical and antapical horns than the holotype of Andalusiella rhomboides. The horns of the latter are transversally folded, so they seem shorter than they really are. All specimens are coming from hole CL 42, and Svalbardella sp. A is located in the same slide as the holotype of Andalusiella rhomboide.
