parvispinum (Deflandre, 1937b, p.77, pl.16 [al. pl.13], fig.5) Davey et al., 1969, p.17. Holotype: Deflandre, 1937b, pl.16 (al. pl.13), fig.5; Fauconnier and Masure, 2004, pl.66, figs.5-6. Originally Hystrichosphaeridium xanthiopyxides var. parvispinum, subsequently Hystrichosphaeridium parvispinum, thirdly Baltisphaeridium parvispinum (Appendix A), fourthly (and now) Prolixosphaeridium parvispinum. Taxonomic junior synonyms (at specific and varietal ranks): Prolixosphaeridium deirense, according to Davey and Verdier (1974, p.636-637) - however, Harding (1990b, p.46) retained Prolixosphaeridium deirense; Prolixosphaeridium elongatum, according to Lentin and Williams (1985, p.294). This combination was not validly published in Davey et al. (1966, p.173), since these authors did not fully reference the basionym. Age: Late Aptian.
