longofilum (Maier, 1959, p.317, pl.32, fig.7) Downie and Sarjeant, 1965, p.92.  Holotype: Maier, 1959, pl.32, fig.7.  Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium.  This combination was not validly published in Downie and Sarjeant (1963, p.91), since these authors did not fully reference the basionym.  Age: middle Oligocene.
