Europe = Sweden.
One recent study found that this species was sister to P. dauurica#R. Internal taxonomy requires revision. Geographical variation appears to be largely clinal, and individual variation considerable#R: proposed race †italica normally included within nominate, as also are hilgerti and borkumensis (latter a new name for pallida), plus sphagnetorum, based on recent analysis#R; caucasica and rossica are subsumed within lucida, furvescens within canescens, and arenicola and buturlini within robusta. Six subspecies currently recognized.
Introduced and reintroduced to many parts of Europe, including Finland, Britain, Russia and France; also successfully introduced to USA and Canada.
