"galea" (Maier, 1959, p.306, pl.29, fig.4) Sarjeant, 1964a, p.176.  Emendation: Sarjeant, 1983, p.110, as Chiropteridium galea.  Holotype: Maier, 1959, pl.29, fig.4; Eisenack and Kjellström, 1975b, p.88a; Fensome et al., 1995, fig.1 - p.1495.  NOW Chiropteridium.  Originally Galea (generic name illegitimate), subsequently Baltisphaeridium, thirdly Areoligera, fourthly Areoligera?, fifthly (and now) Chiropteridium.  Taxonomic junior synonyms: Chiropteridium dispersum, Galea (subsequently Baltisphaeridium) mespilana and Galea (subsequently Baltisphaeridium) levis, all according to Sarjeant (1983, p.108-109); Membranophoridium multispinatum, by implication in Brosius (1963, p.48) and Gocht (1969, p.63), who considered Membranophoridium multispinatum to be a taxonomic junior synonym of Galea (as Chiropteridium) dispersa, which is now a taxonomic junior synonym of Galea (now Chiropteridium) galea; Membranophoridium (subsequently Chiropteridium) partispinatum, by implication in Matsuoka and Bujak (1988, p.40), who considered Membranophoridium partispinatum to be a taxonomic junior synonym of Galea (as Chiropteridium) mespilana, which is now a taxonomic junior synonym of Galea (now Chiropteridium) galea.  N.I.A.  Age: Oligocene.
