pateum (Timofeev, 1959, p.52, pl.4, fig.4) Downie and Sarjeant, 1965, p.94.  Holotype: Timofeev, 1959, pl.4, fig.4.  Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium.  This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym.  Age: Early Ordovician.
