Subspecies
Macronous gularis (Sibley and Monroe 1990, 1993) has been split into Striped Tit-Babbler (Mixornis gularis) and Bold-striped Tit-Babbler (Mixornis bornensis) following Collar (2006).
Formerly treated as conspecific with Bold-striped Tit-Babbler (Mixornis bornensis). Geographically isolated Philippine subspecies woodi distinctive, and perhaps better treated as a separate species or, conceivably, as conspecific with Grey-faced Tit-Babbler (Mixornis kelleyi), with which (along with Grey-cheeked Tit-Babbler (Mixornis flavicollis)) it shares song type. Many subspecies weakly differentiated, and published diagnoses often based on trivial differences and not always supported by museum evidence. The number of subspecies is probably too high, and several may in due course be synonymized.
The following 14 subspecies are recognised:
rubicapilla (Tickell, 1833) - Nepal, Bhutan, north-eastern and east-central India and Bangladesh.
ticehursti (Stresemann & Heinrich, 1940) - Western and south-western Myanmar.
sulphureus (Rippon, 1900) - Northern, eastern (except extreme eastern part) and south-eastern Myanmar (including northern Tenasserim), north-western and western Thailand and southern China (south-western Yunnan).
lutescens (Delacour, 1926) - North-eastern Myanmar, extreme north-western and north-eastern Thailand, southern China (south-eastern Yunnan, south-western Guangxi), Laos and northern Vietnam (Tonkin, northern Annam).
kinneari (Delacour & Jabouille, 1924) - Central Vietnam (central Annam).
saraburiensis Deignan, 1956 - East-central Thailand and western Cambodia.
