Subspecies
Has often been treated as conspecific with Marshall's 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.
