Cyclonephelium microfenestratum
Cyclonephelium microfenestratum Bujak, 1976
Now Glaphyrocysta. Originally Cyclonephelium, subsequently (and now) Glaphyrocysta.
Holotype: Bujak, 1976, pl.4, figs.4-5; Bujak et al., 1980, pl.14, fig.1
Locus typicus: Whitecliff Bay, Isle of Wight, England
Stratum typicum: Late Eocene
Original diagnosis: Bujak, 1976, p.112
Central body dorsoventrally compressed, outline subcircular or subquadrate, with or without one or two antapical lobes. Autophragm granulate or reticulate on middorsal and midventral areas, elsewhere scabrate to granulate. Processes fibrous, solid, arranged in arcuate or linear complexes on cingular zone, elsewhere in annulate or soleate complexes. Additional processes often present inside soleate and annulate complexes. More than eight processes usually comprising each apical, precingular, postcingular and antapical process complex. Processes of each complex typically interconnected along their lengths, bearing distal process platforms formed of tightly interwoven trabeculate networks. Platforms of adjacent process complexes often joined by trabeculae. Reflected process complex tabulation 4", 5", xc, 5""", ?p, 1""""; plate areas 6", 6""", anterior sulcal area, and middorsal and midventral areas without process complexes. Plate area 3" sometimes with single process rather than process complex. Archeopyle apical, tetratabular. Operculum simple and usually detached. Short, accessory archeopyle sutures often partially defme six precingular plate areas, and an anterior sulcal Plate area offset to the left on the ventral surface.
