Geographical variation rather limited and partially clinal; nominate race intergrades widely with dartfordiensis in SW France and NW Iberia and with toni in S Iberia. Proposed races corsa (from Corsica) and naevalbens (from SE Italy) fall within range of variation of nominate and thus are synonymized with it; similarly, aremorica (from NW France) is synonymized with dartfordiensis, and tingitana (from Morocco) with toni. Three subspecies recognized.

Subspecies and Distribution
  • S. u. dartfordiensis Latham, 1787 – S England and W France S to extreme N Iberian Peninsula.
  • S. u. undata (Boddaert, 1783) – S France, Iberian Peninsula, Balearic Is (Menorca, locally in N Mallorca), Corsica, Sardinia and Italy (including parts of Sicily).
  • S. u. toni E. J. O. Hartert, 1909 – NW Africa (NE Morocco E to N Tunisia), and perhaps S Iberia; non-breeding S to N edge of Sahara.
