Hystrichosphaeridium cambayense
From Fensome et al., 2019:
Hystrichosphaeridium cambayense Varma and Dangwal, 1964, p.63, pl.1, figs.1–2. Holotype: Varma and Dangwal, 1964, pl.1, fig.1. Originally Hystrichosphaeridium, subsequently (and now) Hystrichosphaeridium?. Questionable assignment: Stover and Evitt (1978, p.56) as a problematic species. Age: Eocene–Oligocene.
---------------------------------------------------------------------------------------------------
Original diagnosis: Varma and Dangwal, 1964, p.63
Body spherical to somewhat angularlv rounded, the angularity most probably attained during fossilisation. Body wall well defined, up to 3µ thick. Body densely granulate, processes rising from the body surface in groups or coalesced bundles situated at fair distances from each other. These groups of processes show a granulation similar to that seen on the body. Observed thickness of the bundles varies from 9 to 30 µm. Individual processes united almost throughout their length, sometimes even in an anastomosing manner. Processes simple or sometimes with slightly bifurcated tips.
Measurements: Diameter of body ca. 44-70 µm , length of processes ca. 15-30 µm.
Affinities:
Varma and Dangwal, 1964, p.63: At first sight the most closely comparable species appears to be H. inodes Klumpp, but the details of H. cambayense are so widely different that they warrant its designation as a new species.
