Glaphyrocysta inculta
From Fensome et al., 2019:
Glaphyrocysta inculta (Morgenroth, 1966b, p.9, pl.2, fig.5) Stover and Evitt, 1978, p.50. Holotype: Morgenroth, 1966b, pl.2, fig.5.
Originally Cyclonephelium, subsequently (and now) Glaphyrocysta. Age: Early Oligocene.
---------------------------------------------------------------------------------------------------
Original description Morgenroth 1966
Derivatio nominis: incultus Latin = unadorned.
Holotype: The one in Slide H2/I preserved specimen shown on Plate 2 Fig. 5.
Paratypoids: H2丨II, H4, HS.
Locus typicus: Depold'sche Ziegelei (south of Helmstedt).
Stratum typicum: Lower Oligocene.
Diagnosis: A species of the genus Cylonephelium with weak granulated capsule. The slender, massive processes extend distally thin cords connected together, forming a simple, large mesh form network.
Description: The thin-walled, slightly flattened dorsoventrally. Capsule has a slightly granulated surface. The antapical pole is
characterized by 2 bulges of different strengths. The apical pole is almost without exception in the form of a pole cap with irregular
Split off into a jagged outline. - The slender massive processes are arranged on a meridional belt and distal by relative strong cords connected together, creating a very coarse mesh, simple form network. - Dorsal and ventral sides of the capsule are usually extension-free.
Dimensions:
Capsule length: 51μ (39μ–61μ)
Capsule width: 42 μ (39μ–45μ)
Capsule height: 37 μ (35μ–39μ)
Specimen length: 89μ (81μ–100μ〉
Specimen width: 83 μ (75μ–90μ)
Pyloma: approx. 30μ
(25 measurements).
Number of specimens examined: 29.
Comparisons: The new species differs in training from Cyclonephelium reticulosum GERLACH, which also occurs in the Oligocene the simple cord-like distal connections of the processes, while in C. reticulosum fine membranous, net-like perforated edges appear. In addition, there are no basal adhesions of the processes. - At C. pastielsi DEFLANDRE & COOKSON, the paws are more tender than the new one. The distal adhesions are also irregular, more like scrub.
