Licracysta
From Williams et al., 2017:
[Licracysta, Fensome et al., 2007, p. 400, 402.
Type species: Licracysta corymbus, Fensome et al., 2007 (pl. 4, figs.9–12)]

Original description: [Fensome et al., 2007]:
Diagnosis:
Proximochorate to usually chorate areoligeracean cysts with a subspheroidal to lenticular central body. Processes ambitally distributed, generally contabular, but typically varying on a single specimen from rarely mesotabular to loosely contabular to nontabular. Processes sometimes dolabrate to weakly licrate and individual processes within each complex commonly branched or connected by trabecula or membranes.
Affinities/Comparison:
Enneadocysta has a maximum of one process per paraplate. The process distribution in Cleistosphaeridium is overall rather than marginate and adjacent processes are only rarely joined into contabular complexes above their bases (pl. 2, fig. 20; pl. 5, figs. 9-11, 13-15, 17-19). Glaphyrocysta does not have dolabrate to licrate processes. In Licracysta there is a tendency for processes in complexes to develop connecting arcuate basal ridges, paralleling a similar development in Cleistosphaeridium. The presence of basal ridges may make it difficult to differentiate Licracysta from Areoligera in some instances, but the development of dolabrate to licrate processes indicates an affinity to Licracysta.
