Hystrichosphaeridium assamicum

From Fensome et al., 2019:
Hystrichosphaeridium assamicum Sah et al., 1970, p.146–147, pl.2, figs.20–21. Holotype: Sah et al., 1970, pl.2, fig.20. Originally Hystrichosphaeridium, subsequently (and now) Hystrichosphaeridium?. Questionable assignment: Stover and Evitt(1978, p.56) as a problematic species. Jain (1982, p.52) recommended that this name be restricted to the holotype. Age: Late Cretaceous.
