F. h. iberiae ( Witherby, 1928)

Muscicapa hypoleuca iberiae Witherby, 1928: 591 .

Type locality Segovia, Spain. The holotype (male; NHMUK 1929.1.15.1) is deposited at the Natural History Museum (Tring, UK). This subspecies is sometimes not recogniZed because it is geographically and morphologically intermediate between F. h. hypoleuca and F. h. speculigera ( Bonaparte, 1850) (von Jordans & Steinbacher 1942; Vaurie 1954; del Hoyo et al. 2006). There is also disagreement as to whether it should be treated as a synonym of F. h. hypoleuca (e.g., Vaurie 1954; Mayr & Cottrell 1986) or of F. h. speculigera (e.g., Curio 1960). This subspecies breeds in the Iberian Peninsula, wintering in western Africa ( Clements et al. 2015).
