Baltisphaeridium
From Williams et al., 2017:
[Baltisphaeridium Eisenack, 1958a, p. 398–399; Emendations: Staplin et al., 1965, p. 188; Eisenack, 1969b, p. 249; Eiserhardt, 1989, p. 88–90.
Acritarch genus.
Although the "type species", Baltisphaeridium longispinosum, was not validly transferred by Eisenack (1958a, p.398), the generic name Baltisphaeridium was validly published since it is based on a previously validly published specific name (I.C.N. Article 40.3). For synonymy see Fensome et al. (1990, p.82–83).
Type species: originally as Ovum hispidum subsp. longispinosum, Eisenack, 1931 (pl.5, fig.10)] ; Baltisphaeridium longispinosum, Eisenack, 1959
