The types and other specimens of Agnostus fallax Linnarsson 1869 are examined and reinterpreted. It is shown that the application of this specific name to many specimens from around the world is largely in error. The species is considered sufficiently different from the type species of Peronopsis, P. Integra (Beyrich, 1845) to warrant erection of a new genus Axagnostus with A. fallax as the type species.
