Sepispinula ambigua

?ambigua (Deflandre, 1937b, p.81, pl.16 [al. pl.13], figs.8–9) Masure in Fauconnier and Masure, 2004, p.500.  Holotype: Deflandre, 1937b, pl.16 (al. pl.13), fig.8; Fauconnier and Masure, 2004, pl.71, figs.6–7.  Originally Micrhystridium (Appendix A), subsequently Cleistosphaeridium, thirdly Polysphaeridium, fourthly Chlamydophorella, fifthly Dapsilidinium, sixthly Gorgonisphaeridium (Appendix A), seventhly Sepispinula?. Taxonomic junior synonyms: Hystrichosphaeridium (now Sepispinula?) huguoniotii, according to Clarke and Verdier (1967, p.54) and Hystrichosphaeridium (now Sepispinula) ancoriferum, both according to Yun Hyesu (1981, p.44) and Schiøler and Wilson (1998, p.328) — however, Masure in Fauconnier and Masure (2004, p.499–500) retained Hystrichosphaeridium (as and now Sepispinula) ancoriferum and Hystrichosphaeridium (as and now Sepispinula?) huguoniotii.  Questionable assignment: Masure in Fauconnier and Masure (2004, p.500) as a problematic species.  Age: Late Cretaceous.
