Remarks:

This species is found in spring (March - May) under driftwood along the Pacific coast from the Queen Charlotte Is., BC, to Humboldt Bay, CA. Benesh (1946) reported that both sexes are flightless. The species was formerly treated as comprising a monotypic genus based on automorphies related to male flightlessness. Paulsen (2017) transferred PlatyceropsisBenesh to subgeneric status within Platyceroidesbased on its close relationship to P. laticollis that renders its monotypic status unsupportable.
