?americana (Pöthe de Baldis and Ramos, 1983, p.432-433, pl.1, figs.6,9) Prössl, 1992b, p.116. Holotype: Pöthe de Baldis and Ramos, 1983, pl.1, fig.9. This combination was not validly published in Prössl (1990, p.99), since that author did not fully reference the basionym. Originally Canningia, subsequently (and now) Tenua? Eisenack. Questionable assignment: Prössl (1992b, p.116); and Courtinat in Fauconnier and Masure (2004, p.557) as a problematic species. Age: Early Aptian.
Parent: Tenua_Eisenack 1958a
