From Fensome et al., 2019:
Chytroeisphaeridia scabrata Pocock, 1972, p.100, pl.27, figs.23–25. Holotype: Pocock, 1972, pl.27, figs.24–25; Jansonius, 1986, pl.3, figs.13–14. Originally Chytroeisphaeridia, subsequently (and now) Chytroeisphaeridia?. Questionable assignment: Stover and Evitt (1978, p.28) as a problematic species.
Age: late Bajocian.

Original description: [Pocock, 1972, p. 100]:

Description:
Vesicle ovoid; apical portion normally somewhat arched; wall single-layered; less than 0.5 µm thick; scabrate; shield-shaped aperture pointed, portion directed apically, developed over one definite area of the vesicle, frequently covered by an operculum; most specimens possess a circular yellow-green punctate body, 8.0-10.0 µm in diameter, appressed to the inside of the vesicle wall; well preserved examples show a small, rounded area of wall thickening occupying the apex of the grain; vesicle transparent; colorless to pale-yellow;

Dimensions:
size range 39.0 (45.5) 49.0 µm x 54.0 (57.5) 66.0 µm.

Supplemental description:

Jansonius, 1986, p.204:

Description:
(Holotype) 53 x 44 µm, broadly ovoid; dorsal side up. Wall uniformly 1 µm thick, smooth outline, possibly minutely scabrate internally, not hyaline but firm and fleshy, possibly two-layered (as indicated by a thin shadow line inside the outline on the right margin).
Precingular archeopyle (19 x 15 µm) clearly delineated by a groove, but operculum still in place;
no cingulum or other paratabulation indicated.
