semitecta (Bujak in Bujak et al., 1980, p.46,48,50, pl.14, figs.2-9; text-fig.13) Lentin and Williams, 1981, p.111. Holotype: Bujak et al., 1980, pl.14, figs.4-6; Fauconnier and Masure, 2004, pl.33, figs.10-11. Originally Cyclonephelium, subsequently (and now) Glaphyrocysta, thirdly Riculacysta (combination not validly published). Lentin and Williams (1993, p.238) retained this species in Glaphyrocysta. Taxonomic senior synonym: Riculacysta perforata, according to Köthe (1990, p.50) - however, Kirsch (1991, p.129), retained Cyclonephelium (as Riculacysta, now Glaphyrocysta) semitectum. Age: Mid Eocene (see Aubry, 1986).
