Wrevittia diutina subsp. tabulacornuta

subsp. tabulacornuta (Prössl, 1990, p.102-103, pl.8, figs.1-2,4-5 ex Prössl, 1992b, p.113,115) Williams et al. 1998, p.642.  Originally Gonyaulacysta diutina subsp. tabulacornuta, subsequently (and now) Wrevittia? diutina subsp. tabulacornuta.  The name Gonyaulacysta diutina subsp. tabulacornuta was not validly published in Prössl (1990, p.102-103), since that author did not specify the lodgment of the holotype.  Age: Early Barremian. Parent: Wrevittia diutina
