Nematosphaeropsis reticulensis
From Fensome et al., 2019:
Nematosphaeropsis reticulensis (Pastiels, 1948, p.49, pl.5, figs.7–10) Sarjeant, 1986, p.9. Emendation: Sarjeant, 1986, p.9,11, as Nematosphaeropsis reticulensis. Holotype: Pastiels, 1948, pl.5, fig.10, unrecognizable according to Sarjeant (1986, p.11). Lectotype: Pastiels, 1948, pl.5, fig.7; Sarjeant, 1986, pl.3, fig.6; designated by Sarjeant (1986, p.11). Originally Cannosphaeropsis, subsequently Adnatosphaeridium, thirdly (and now) Nematosphaeropsis. De Coninck (1986a, p.17–18) also proposed this combination. Age: Early Eocene.

Lectotype: Pastiels, 1948, pl.5, fig.10 (designated by Sarjeant, 1986)
Locus typicus: Belgium
Stratum typicum: Early Eocene
---------------------------------------------------------------------------------------------------
Emended description: Sarjeant, 1986, p. 9
Cyst spiniferate, trabeculate, hercotabulate. Central body spheroidal to broadly ovoidal. Processes gonal in situation, solid or hollow but always closed and furcate distally. Most processes are trifurcate, but the cingular processes are bifurcate. The process furcations are themselves bifurcate, giving rise to trabeculae connecting them to immediately adjacent processes. Length of processes between one-third and one-half the equatorial diameter of the cyst. Surface of phragma typically laevigate; septa between paraplates not marked. Paratabulation gonyaulacoid, indicated by the alignment of the trabeculae only; ?4', 6'', 6c, 6''', Ip, 1''''. Archaeopyle single-plate precingular, type P (3'' only); operculum free.
