Cyclonephelium hirtellum
From Fensome et al., 2019:
Cyclonephelium hirtellum (Alberti, 1961, p.28, pl.4, fig.20) Davey, 1978, p.894.
Holotype: Alberti, 1961, pl.4, fig.20
Taxonomic senior synonym: Cyclonephelium distinctum, according to Fensome et al. (2016b, p.39)..
Originally and fourthly Circulodinium, subsequently Canningia, thirdly Cyclonephelium. Backhouse (1988, p.83) considered Tenua (as Cyclonephelium) hystrix to be the possible taxonomic senior synonym of this species. Below (1981a, p.10) also proposed this combination.
Age: Valanginian–Hauterivian.

Translation Alberti, 1961: LPP
Original diagnosis: Alberti, 1961, p.28: Circulodinium hirtellum
Shell flattened, outline irregulary rounded, slightly longer than broad. Short apical protrusion. Two antapical bulges of unequal size. Epitheca slightly smaller than hypotheca. Surface of shell, ecxept central parts of dorsal and ventral sides, covered with short, pointed, thorn-like spines.
Description: Short, blunt apical horn (c. 7 Ám). Two rounded antapical horns of unequal size. The length and distribution of the at the bases broadened thorns variable. Membrane yellow-brown and transparent.
Dimensions: Holotype - length 102 Ám, breadth 93 Ám, length of thorns 3-4 Ám, length of apical horn 7 Ám, antapical bulges 10-12 Ám. Range - length 98-106 Ám, breadth 88-97 Ám.
