"colligerum" (Deflandre and Cookson, 1955, p.278-279, pl.7, fig.3) Downie and Sarjeant, 1965, p.88.  Emendations: Cookson, 1965a, p.86; Goodman and Witmer, 1985, p.77-78, both as Diphyes colligerum.  Holotype: Deflandre and Cookson, 1955, pl.7, fig.3.  NOW Diphyes.  Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly (and now) Diphyes.  This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym.  Age: Early Eocene.
