Errivaspis is an extinct genus of pteraspid heterostracan agnathan vertebrate known from fossils at the Wayne Hereford Quarry, of Early Devonian England, and of Podolia, Early Devonian Ukraine. It was originally described by Dr. Errol Ivor White as one of five form-variants of Pteraspis rostrata, i.e., "Pteraspis rostrata var. waynesis.{{cite book | url=https://books.google.com/books?id=b8ROAQAAIAAJ&q=birkenia | title=Fossil fishes of Great Britain (Volume 16 of Geological conservation review series) | publisher=Joint Nature Conservation Committee |author1=Dineley, David L. |author2=Metcalf, S. J. | year=1999 | pages=133, 134(675) | isbn=9781861074706}} In 1984, Alain Blieck moved var. waynesis into its own genus, Errivaspis, which he named after Dr. White.Blieck, Alain. "Les Hétérostracés Ptéraspidiformes, Agnathes du Silurien-Dévonien du Continent nord-atlantique et des blocs avoisinants: révision systématique, phylogénie, biostratigraphie, biogéographie." (1984). Other later researchers would then mistakenly assume that Blieck synonymized the entire genus of Pteraspis into Errivaspis.
