Subspecies
Amami Thrush (Zoothera major), Scaly Thrush (Zoothera dauma) and Horsfield's Thrush (Zoothera horsfieldi) (Sibley and Monroe 1990, 1993) have been lumped into Zoothera dauma following Collar (2004). Sri Lanka Thrush (Zoothera imbricata) from Sri Lanka, previously considered a subspecies of Scaly Thrush (Zoothera dauma) following Sibley and Monroe (1990, 1993), is treated as a distinct species following Rasmussen and Anderton (2005).
First four, at least, of these previously considered conspecific with present species, and Bassian Thrush (Zoothera lunulata) possibly better treated as such.

Non-breeding southern and south-eastern China, Taiwan, mainland south-eastern Asia, northern and western Philippines.

dauma (Latham, 1790) - Western Himalayas (including Pakistan) east to Assam, south-central China (Sichuan south to Yunnan and Guangxi), northern Myanmar, northern and western Thailand and northern Indochina. Non-breeding mainly southern and south-eastern Asia.
