This species is found along streams in evergreen forest at 200-1,200 m, but mainly at 400-1,000 m.

This species occurs in southern China including Hainan Island (rare), eastern Nepal (vagrant), Bhutan (rare), north-east India (rare), Bangladesh (vagrant), Myanmar (scarce to fairly common in the north, west and south), north-west Thailand (very rare visitor), Laos (uncommon to locally common in the north and Annamite mountains, scarce further south) and Viet Nam (locally fairly common in west Tonkin and Annam). Given its linear distribution along rivers, and thus restricted range, the total population size is possibly moderately small.

Conservation Actions Underway
None are known.

Conservation Actions Proposed
Conduct repeated surveys throughout its range to clarify its current population status, as well as assess population trends and rates of range contraction. Conduct ecological studies to identify habitat associations and potential threats. Grant protection to areas of suitable habitat. Enforce laws against river pollution where applicable. Strengthen legislation against aquatic pollution throughout the species' range.
