"hystrix" (Eisenack, 1958a, p.410, pl.23, figs.1-4; text-fig.10) Davey, 1978, p.894.  Emendation: Sarjeant, 1985a, p.94-95, as Tenua hystrix.  Holotype: Eisenack, 1958a, pl.23, fig.1; Sarjeant, 1985a, pl.10, fig.5; Sarjeant, 1992b, fig.1; Fauconnier and Masure, 2004, pl.80, fig.3.  NOW Tenua Eisenack.  Originally (and now) Tenua Eisenack, subsequently Cyclonephelium.  Taxonomic junior synonyms: Tenua hystricella, according to Eisenack and Kjellström (1972, p.1039); Cyclonephelium (as Cerbia) tabulata, according to Sarjeant (1985a, p.95-96; 1992b, p.681).  Backhouse (1988, p.83) considered Circulodinium hirtellum to be a possible taxonomic junior synonym of this species.  Sarjeant and Stover (1978, p.52) also proposed this combination.  N.I.A.  Age: Aptian.
