Amphorosphaeridium robustum
From Fensome et al., 2019:
Amphorosphaeridium? robustum, (Salujha and Kindra, 1981, p.52, pl.3, figs.55–56) Jain and Garg, 1982, p.69.
Holotype: Salujha and Kindra, 1981, pl.3, fig.55.
Originally Hystrichokolpoma, subsequently (and now) Amphorosphaeridium?.
Questionable assignment: Jain and Garg (1982, p.69). Jain and Garg (1982, p.69) indicated that one of the two specimens illustrated by Salujha and Kindra (1981, pl.3, fig.56) is assignable to a species of Achomosphaera.
Age: Early Paleocene.

Original description: [Salujha and Kindra, 1981]:
Hystrichokolpoma robusta sp. nov.
Pl. 3, figs. 55-56
HOLOTYPE : Pl. 3, fig. 55.
DIAGNOSIS AND DESCRIPTION : Brown, almost circular, size 95-135 μ including processes); processes 12-20 μ long, slightly broad based,
occasionally furcating near he base, tips blunt, furcating into two or three branches; exine +/- 2.5 μ thick, body circular, bearing broad reticulations, muri +/- 2 μ thick with wide lumina bearing foveola, foveola +/- 1.5 μ wide.
COMPARISON : Hystrichokolpoma rigaudae described by Deflandre and Cookson (1955; PI, 6, figs. 6, 10) differs in being smaller in size with distincly two types of processes and membrane of the shell being smooth or indistinctly granular. H. indica described above also has two types of processes with faintly reticulate exine.
