Previously placed in Bradypterus. Some confusion with L. mandelli until vocal differences indicated existence of two separate species in NE Indian Subcontinent; genetics demonstrate that they are not close relatives#R. Birds from W Myanmar (Arakan Yomas) described as race saturatus (preoccupied, replacement name ticehursti), and subsequent specimens from S China (Yunnan) and N Thailand claimed to be of this form; first two, however, now considered to be merely very dark juveniles, while Thai specimen is a dark L. mandelli, and this race no longer regarded as valid. Monotypic.
NE India (from Darjeeling, in West Bengal, E to Arunachal Pradesh and Nagaland), Bhutan, W & N Myanmar, S & SE China and N Vietnam; probably also NE Bangladesh. Non-breeding also S Myanmar and NW & NE Thailand#R.
