Subspecies
Often placed in genus Trichastoma. Mainland subspecies weakly differentiated, and perhaps only concreta and baweana worthy of recognition.
Proposed subspecies amabile (low elevations from eastern Nepal east to eastern Assam, in north-eastern India) and rufescentior (from southern Myanmar and southern Thailand) both merged with nominate. Individuals of this species observed in south-eastern part of north-eastern Thailand, south-western Laos and adjacent north-eastern Cambodia have not been assigned to subspecies.
The following 8 subspecies are recognised:
abbotti Blyth, 1845 - Nepal and extreme southern Bhutan east to north-eastern Indian states, eastern Bangladesh, south-western and southern Myanmar (including Tenasserim), western and southern Thailand and north-western Peninsular Malaysia.
