?nanus (Wetzel, 1933b, p.43, pl.4, fig.23; text-fig.13 ex Lentin and Williams, 1985, p.322) Sarjeant, 1985b, p.145.  Emendation: Sarjeant, 1985b, p.145, as Prolixosphaeridium nanus.  Holotype: Wetzel, 1933b, pl.4, fig.23; Sarjeant, 1985b, pl.2, figs.6–7.  Originally Hystrichosphaera pilosa forma nanus (name not validly published), subsequently Sentusidinium pilosum? subsp. nanus, thirdly Prolixosphaeridium nanus, fourthly (and now) Prolixosphaeridium? nanus.  Questionable assignment: Fauconnier and Monteil in Fauconnier and Masure (2004, p.462–463).  The name Hystrichosphaera pilosa forma nanus was not validly published in Wetzel (1933b) since the species combination Hystrichosphaera pilosa was not validly published.  N.I.A.  Age: Late Cretaceous.

Parent: Prolixosphaeridium
