"?huguoniotii" (Valensi, 1955a, p.38-39, text-fig.2a) Davey, 1969a, p.155-156. Holotype: Valensi, 1955a, text-fig.2a; Fauconnier and Masure, 2004, pl.72, figs.1-3. NOW Sepispinula?. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium, fourthly Cleistosphaeridium?, fifthly Chlamydophorella, sixthly Sepispinula, seventhly (and now) Sepispinula?. Questionable assignment: Stover and Evitt (1978, p.32) as a problematic species. Taxonomic senior synonym: Micrhystridium (as Polysphaeridium, now Sepispinula?) ambiguum, according to Yun Hyesu (1981, p.44) and Schiøler and Wilson (1998, p.328) - however, Masure in Fauconnier and Masure (2004, p.500) retained Hystrichosphaeridium (as and now Sepispinula?) huguoniotii. Taxonomic junior synonym: Hystrichosphaeridium (subsequently Sepispinula) ancoriferum, according to Clarke and Verdier (1967, p.54) - however, Masure in Fauconnier and Masure (2004, p.499) retained Hystrichosphaeridium (as and now Sepispinula) ancoriferum.
