 Tetlie erected a new genus due to the obvious similarity with "Hughmilleria" with several derived characteristics shared with the slimonids and pterygotids.The name "Herefordopterus" derives from Herefordshire, where the vast majority of its fossils have been found.In addition, the poorly known species "Hughmilleria acuminata", previously known only by two telsons, was synonymized with "Herefordopterus" due to being anteriorly wide.
