longispinosoides (Sannemann, 1955, p.329–330, pl.1, fig.10; pl.2, figs.1–4; pl.3, figs.6,8; pl.6, figs.1–6; text-figs.9a–b) Downie and Sarjeant, 1965, p.92.  Holotype: Sannemann, 1955, pl.6, fig.1.  Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium.  This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym.  Age: Devonian (late Givetian).
