Errivaspis is an extinct pteraspid heterostracan genus known from fossils at the Wayne Hereford Quarry, of Early Devonian England, and of Podolia, Early Devonian Ukraine. It originally described by Dr. E. I. White as one of five form-variants of Pteraspis rostrata, i.e., "Pteraspis rostrata var. waynesis. In 1984, Alain Blieck moved var. waynesis into its own genus, Errivaspis, which he named after Errol Ivor White.
