Baltisphaeridium galea
Baltisphaeridium galea, (Maier, 1959), Sarjeant, 1964
Now Chiropteridium. Originally Galea (an illegitimate generic name), subsequently Baltisphaeridium, thirdly Areoligera, fourthly Areoligera?, fifthly (and now) Chiropteridium.
Tax. sr. synonym of Chiropteridium dispersum Gocht, 1960, according to Sarjeant, 1983.
Tax. sr. synonym of Galea (al. Baltisphaeridium) mespilanum Maier, 1959, according to Sarjeant, 1983.
Tax. sr. synonym of Galea (al. Baltisphaeridium) levis Maier, 1959, according to Sarjeant, 1983.
Tax. sr. synonym of Membranophoridium multispinatum Gerlach, 1961, according to Brosius, 1963 and Gocht, 1969.
Tax. sr. synonym of Membranophoridium (al. Chiropteridium) partispinatum Gerlach, 1961, by implication, according to Matsuoka and Bujak, 1988. Fensome et al., 1990 stated: "The following observations can be made: Article 68.1 of the LC.B.N. implies that a specific epithet is to be considered valid at the date of its original proposal provided all requirements for valid publication are met, except that the generic name is illegitimate; apart from the fact that the generic name Galea is an illegitimate homonym, Maier, 1959 fulfilled all requirements for the equivalent of valid publication under the I.C.Z.N.; and the I.C.B.N. accepts all names thus published under alternate recognized codes from the dates of their valid publication (or equivalent), if these names are transferred into the jurisdiction of the I.C.B.N. Thus Baltisphaeridium (now Chiropteridium) galea (Maier, 1959) Sarjeant, 1964, is here considered to be a validly published botanical name, with priority of the specific epithet dating back to 1959. In considering Galea (as Chiropteridium) galea Maier, 1959, Galea (al. Baltisphaeridium) levis Maier, 1959 and Galea (al. Baltisphaeridium) mespilanum Maier, 1959, to bo synonymous, Sarjeant, 1983 chose Galea (as Chiropteridium) galea to be the senior name; as the first synonymizing author, his choice of epithet has priority. Lentin and Williams, 1989 considered Galea (as Chiropteridium) mespilanum to be the senior name."
