Subspecies
Garrulax leucolophus (Sibley and Monroe 1990, 1993) has been split into White-crested Laughingthrush (Garrulax leucolophus) and Sumatran Laughingthrush (Garrulax bicolor) following Collar (2006).
Often treated as conspecific with Sumatran Laughingthrush (Garrulax bicolor). Subspecies form two groups, differing in plumage pattern: western nominate and patkaicus, with olive-brown posterior upperparts and clear-cut breast-line, and eastern belangeri and diardi, with chestnut upperparts and more extensive, less well-demarcated white underparts.
The following 4 subspecies are recognised:
leucolophus (Hardwicke, 1815) - Southern Himachal Pradesh and Nepal east to north-eastern India (Arunachal Pradesh except south-east) and adjacent southern China (south-eastern Xizang).
patkaicus Reichenow, 1913 - South-eastern Arunachal Pradesh and north-eastern Indian hill states (south of southern Brahmaputra), eastern Bangladesh, Myanmar (except south-central, eastern and south-east) and southern China (western and south-western Yunnan).
belangeri Lesson, R, 1831 - South-central and southern Myanmar (including Tenasserim) and western Thailand.
diardi (Lesson, R, 1831) - South-eastern Myanmar, north-west, north-eastern and south-eastern Thailand, Indochina and southern China (southern and south-eastern Yunnan).
