Subspecies
Bradypterus thoracicus (Sibley and Monroe 1990, 1993) has been split into Spotted Grasshopper-warbler (Locustella thoracica) and Baikal Grasshopper-warbler (Locustella davidi) following Round and Loskot (1995).
Usually considered conspecific with Baikal Grasshopper-warbler (Locustella davidi), but differs in song and migratory behaviour, as well as morphologically. Western subspecies kashmirensis currently of uncertain taxonomic status and may represent a separate species.
The following 3 subspecies are recognised:

thoracica (Blyth, 1845) - Breeds central and eastern Himalayas from Nepal, Bhutan and north-eastern India east to northern Myanmar, and western and southern China (from south-eastern Xizang and Yunnan east to north-central Sichuan, Guizhou, and Dayao Shan region of Guangxi).
