"<I><B>irregulare</B></I>" ([[Pocock, 1962]], p.82, pl.15, figs.228-229) [[Davey and Williams, 1969]], p.5.&nbsp; Holotype: [[Pocock, 1962]], pl.15, figs.228-229, lost according to [[Jansonius, 1986|Jansonius (1986]], p.220).&nbsp; Lectotype: [[Jansonius, 1986]], pl.4, fig.3, designated by [[Jansonius, 1986|Jansonius (1986]], p.214 - caption to pl.4); [[Fauconnier and Masure, 2004]], pl.55, fig.9.&nbsp; Originally <I>[[Hystrichosphaeridium]]</I>, subsequently <I>Oligosphaeridium</I>.&nbsp; <B>Taxonomic senior synonym</B>: <I>[[Hystrichosphaeridium albertense|Hystrichosphaeridium]]</I> (as <I>[[Oligosphaeridium albertense|Oligosphaeridium]]</I>) <I>[[Hystrichosphaeridium albertense|albertense]]</I>, according to [[Jansonius, 1986|Jansonius (1986]], p.213).&nbsp; Taxonomic junior synonyms: <I>[[Hystrichosphaeridium coelenteratum|Hystrichosphaeridium]]</I> (as <I>[[Oligosphaeridium coelenteratum|Oligosphaeridium]]</I>?) <I>[[Hystrichosphaeridium coelenteratum|coelenteratum]]</I>, <I>[[Hystrichosphaeridium dispare|Hystrichosphaeridium]]</I> (as <I>[[Oligosphaeridium dispare|Oligosphaeridium]]</I>?) <I>[[Hystrichosphaeridium dispare|dispare]]</I>, <I>Hystrichosphaeridum</I> (as <I>[[Oligosphaeridium reniforme|Oligosphaeridium]]</I>) <I>reniforme</I>, all according to [[Stover and Evitt, 1978|Stover and Evitt (1978]], p.69).&nbsp; This combination, as a questionable assignment, was not validly published in [[Davey and Williams, 1966b|Davey and Williams (1966b]], p.77), since these authors did not fully reference the basionym.&nbsp; Fauconnier and Cornu in [[Fauconnier and Masure, 2004|Fauconnier and Masure (2004]], p.404) listed this as a problematic species but apparently accepted the synonymy cited above.&nbsp; Age: Late Barremian-Aptian.
