triplicativum (Timofeev, 1959, p.55, pl.4, fig.16) Downie and Sarjeant, 1965, p.98.  Holotype: Timofeev, 1959, pl.4, fig.16.  Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium.  This combination was not validly published in Downie and Sarjeant (1963, p.90-91), since these authors did not fully reference the basionym.  Age: Early Ordovician.
