Impagidinium spongianum
Impagidinium spongianum Sütő-Szentai, 1985, p.519, pl.81, fig.6 (non 5 — see below).
This name was not validly published in Sütő-Szentai (1982a, pl.5, fig.3), who did not give a description. Sütő-Szentai (1990, pl.2, fig.3 — p.860) also cited this species as new.
The nomenclatural status of this species is in question because Sütő-Szentai (1985, p.519 and caption to pl.81) indicated her pl.81, fig.5 as the holotype; however, as L. Londeix (pers. comm.) has pointed out, this specimen had been previously designated as a paratype of Millioudodinium (now Apteodinium?) foveolatum, and does not accord in morphology with the genus Impagidinium. It appears that the holotype was thus incorrectly indicated and should have been cited as pl.81, fig.6 in Sütő-Szentai (1985) (the same specimen as the single illustration labelled as Impagidinium spongiosum in Sütő-Szentai, 1982a, pl.5, fig.3). This is an unusual situation and it is unclear how ICN rules might apply, although generally typographic errors are not reasons for invalidating a name. We thus provisionally accept that Impagidinium spongianum was validly published in Sütő-Szentai (1985) despite the apparently incorrect indication of the holotype.
Holotype: Sütő-Szentai, 1982a, pl.5, fig.3; Sütő-Szentai, 1985, p.519, pl.81, fig.6 (non 5 — see below).
Age: late Miocene.
