Subspecies
Has often been treated as conspecific with White-tailed Iora (Aegithina nigrolutea). Delineation of subspecies complicated by individual variation in amount of black on cap and upper body of males, intercalation of a male eclipse plumage of varying distinctness from breeding dress, some broad geographical intergradation zones (especially in Indian Subcontinent), and inter-population convergence (including of colour tones of eclipse plumages).
Proposed subspecies singapurensis and micromelaena of Malay Peninsula and islands absorbed within range of variation of horizoptera; subspecies trudiae (from Brunei Bay, in northern Borneo) and djunkulanensis (extreme western Java) treated as local intergrades between larger neighbouring entities.
The following 11 subspecies are recognised:
septentrionalis Koelz, 1939 - Foot of north-western Himalayas in northern India (Punjab, Himachal Pradesh).
tiphia (Linnaeus, 1758) - Foot of Himalayas from northern India (eastern from Punjab) east to Bangladesh, and adjacent western Myanmar.
humei Baker, ECS, 1922 - Central Indian Subcontinent (eastern from Rajasthan).
multicolor (Gmelin, JF, 1789) - Extreme southern India and Sri Lanka.
philipi Oustalet, 1886 - South-central China (Yunnan), eastern Myanmar, northern and central Thailand and northern and central Indochina.
horizoptera Oberholser, 1912 - Southern Myanmar and central Thailand south to Malay Peninsula, and Sumatra and satellites (Nias I, Riau and Lingga Archipelagos, Bangka).
cambodiana Hall, BP, 1957 - South-eastern Thailand and southern Indochina.
aequanimis Bangs, 1922 - Western Philippines (Palawan) and northern Borneo (Sabah), and satellite islands.
