It was recombined as Richterarges ethnikos by Adrain (1994).
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. M. Adrain 1994||Richterarges ethnikos has a plesiomorphic pattern of nine border spines similar to that of Borealarges, although other aspects of its morphology, particularly cranidial features, make assignment to Richterarges unambiguous.|
