Hitherto treated as conspecific with G. bispecularis and G. leucotis (see both, below). Geographical variation complex, with races divisible into six groups: European “glandarius group” (first eleven races listed below), N African “cervicalis group”, Middle Eastern “atricapillus group”, Caspian single-taxon “hyrcanus group”, Siberian “brandtii group” and Japanese “japonicus group”. Numerous additional forms have been described, most referable to intermediate populations, and best treated as synonyms: thus, armoricanus and caledoniensis included in rufitergum; septentrionalis in nominate; lusitanicus in fasciatus; yugoslavicus and jordansi in albipectus; oenops and theresae in minor; rhodius, zervasi, chiou, susianae and hansguentheri in anatoliae; nigrifrons in krynicki; caspius in hyrcanus; sewerzowii, bambergi, pallidifrons, kurilensis and ussuriensis in brandtii; diaphorus in pekingensis; namiyei in japonicus; and schimoizumii in hiugaensis. Twenty-seven subspecies currently recognized.
