Hystrichosphaeridium sahii

?sahii Lentin and Williams, 1993, p.331.  Holotype: Sah et al., 1970, pl.2, fig.16.  Originally Hystrichosphaeridium robustum (name illegitimate), subsequently (and now) Hystrichosphaeridium sahii.  Questionable assignment: Masure and Foucher in Fauconnier and Masure (2004, p.313) as a problematic species.  This is the substitute name for Hystrichosphaeridium robustum Sah et al., 1970, p.146, pl.2, figs.16–17 (an illegitimate name).  Jain (1982, p.52) recommended that this species be restricted to the holotype.  Age: Late Cretaceous.

Parent: Hystrichosphaeridium
