Kleithriasphaeridium atlasiense
From Fensome et al., 2019:
Kleithriasphaeridium atlasiense (Below, 1982c, p.12, pl.3, figs.2a–c; text-figs.2a–c) Torricelli, 2001, p.100. Holotype: Below, 1982c,
pl.3, figs.2a–c; Fauconnier and Masure, 2004, pl.43, figs.1–4. Originally Hystrichosphaeridium?, subsequently (and
now) Kleithriasphaeridium. Age: Albian.

Original description (Below, 1982) Translation PKB 2025
Diagnosis: Spheroidal, two-layered cyst with a low apical bulge. The periphragm is very finely punctured and forms mostly equally long appendages. They reflect according to a gonyaulocoid pattern: 4', 6, 6a, 6c, 6"', 1pc, 1"", ra, rs, ps, ls, with one process per paraplate. The appendages are hollow, closed proximally and distally, and tubiform with a minimal diameter. Their distal margin is irregularly dissected. An archaeopyle was not observed.
Description: The appendages ideally reflect a complete goniaulacoid paneling. In one specimen, even the parasulcal plates as, ra, rs, ls, and ps are reflected by appendages that are thinner and shorter than the other prominences. Another individual, however, only shows as, rs, and a further process in the posterior region of the parasulcus (?ps). Appendages 1"', 2"', and pc are generally smaller than all other processes of the apical, precingulate, cingulate, and postcingulate plate ring, which, at about 1/4 to 1/6 of the central body diameter, are all more or less the same length. The antapical process is also not prominent, so that the new species is not assigned to the genus Florentinia. The hollow appendages are somewhat expanded basally, decrease in diameter in the median direction, and are weakly dissected and denticulate. Some walls of the appendages are weakly fenestratified.
Dimensions: Holotype: Diameter of the central body 50 µ, length of the appendages 8-10 µ; other specimen: Diameter of the central body 45 µ, length of the appendages 9-11 µ.
Material: 3 specimens.
Occurrence: Profile E (8): Alb.
