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: middle Eocene (see Aubry, 1986).
