Leberidocysta chlamydata subsp. schioeleri
From Fensome et al., 2019:
Leberidocysta chlamydata subsp. schioeleri Slimani, 1996, p.375, pl.1, figs.A–G ex Slimani 2001b, p.3,5. Holotype: Slimani, 1996,
pl.1, figs.A–D; Slimani, 2001a, pl.1, figs.10–13. This name was not validly published in Slimani (1996) since no English or Latin description or diagnosis was provided. Slimani (2001b, p.3) cited the epithet as "schiølerii"; with latinization of the diacritical marks ("ø" to "oe" and correction of the ending ("er" endings takes a single "i" in the genitive), the epithet is to be cited as "schioeleri". Age: late Campanian–earliest Danian.

Original description (Slimani, 1996):
Name derivation: In honor of Dr. Poul Schiøler, Geological Survey of Denmark, Copenhagen, Denmark.
Type horizon: Campanian
Occurrence: Beutenaken: scales 2 to 20 (Upper Campanian); Hallembaye: scales 4 to 74 (Upper Campanian – Lower Maastrichtian); Turnhout: -966.50 to -759.89 m (Upper Campanian – Lower Danian).
Description: This is a subspecies of Leberidocysta chlamydata with an endophragm and periphragm connected by a few processes. The latter are solid, slightly flared distally, and approximately 1 to 8 in diameter. There is consistently a group of 3 processes in each specimen observed. The cyst is usually oval to ellipsoidal, the endophragm is coarsely warted, while the periphragm is smooth to dotted. A slight indication of paratabulation is very rarely observed on the endocyst. The archaeopyle is apical with a zigzag margin. The free operculum is isolated or adherent.
Dimensions:
Length of the pericyst: holotype (with operculum), 70 µm; paratype (without operculum), 64 µm; other specimens, 60-65 µm.
Pericyst width: holotype, 50 µm; Paratype, 56 µm; other specimens, 50-62 µm.
Endocyst length: Holotype, 46 µm; paratype, 40 µm; other specimens (without operculum), 40-50 µm
Endocyst width: Holotype, 34 µm; paratype, 32 µm; other specimens, 32-42 µm.
Number of specimens measured: 7
Remarks: We share the same opinion as Schiøler and Wilson (1993:347) who consider that this morphotype differs from Leberidocysta chlamydata (Cookson and Eisenack, 1962) Stover and Evitt (1978) by the presence of processes connecting the endophragm and the periphragm. Several lower Santonian specimens figured under the name of the species chlamydata by several authors do not possess these processes.
