"subsp. trabeculosum" (Slimani and Louwye, 2013, p.13,15; pll.2, figs.1-9,11,13) Williams and Fensome, 2016, p.140.  Holotype: Slimani and Louwye, 2013, pl.2, figs.1-3.  NOW Cribroperidinium wilsonii (Yun Hyesu, 1981) subsp. trabeculosum.  Originally (and now) Cribroperidinium wilsonii (Yun Hyesu, 1981) subsp. trabeculosum subsequently Cribroperidinium graemei subsp. trabeculosum.  Slimani and Louwye (2013) did not specify whether they were including this subspecies in Cribroperidinium wilsonii (Yun Hyesu, 1981) Poulsen or Cribroperidinium wilsonii (Slimani, 1994) Schiøler.  Williams and Fensome (2016, p.140) assumed that the intended assignment was to the latter, which is illegitimate, and so transferred the subspecies to the substitute name Cribroperidinium graemei.  However, H. Slimani (personal communiication to GLW) affirms that the taxon was intended to be a subspecies of Cribroperidinium wilsonii (Yun Hyesu, 1981) Poulsen.  Age: Late Campanian.

Parent: Cribroperidinium graemei
