Pterostichinae is a subfamily of ground beetles. It belongs to the advanced harpaline assemblage, and if these are circumscribed sensu lato as a single subfamily, Pterostichinae are downranked to a tribe Pterostichini. However, as the former Pterostichitae supertribe of the Harpalinae as loosely circumscribed does seem to constitute a lineage rather distinct from Harpalus, its core group is here considered to be the present subfamily and the Harpalinae are defined more narrowly.
