Geographic Range [top]
Range Description: The species range extends from Tonkin in northern Viet Nam across tropical southern China to Fujian and includes the islands of Hainan and Taiwan. Originally described from Tonkin (Martin 1904) from where it has not been recorded since. Lieftinck et al. (1984) summarised Taiwanese records from north Taiwan (Shihting) and south Taiwan (Mutantsun). Chao (1990) recorded specimens from Fujian and Wilson (1995, 1997) recorded specimens from several sites in Hong Kong. Wilson (1999) and Wilson and Xu (2009) recorded specimens from two sites in Guangdong. Wilson (2005) recorded the species from Mulun, Guangxi and Wilson and Reels (2001) provided a record of several specimens collected from Hainan. The species has also been recorded from central Lao PDR (Yokoi 2000).

Population [top]
Population: The species occurs in muddy streams and irrigation ditches in tropical southern China and northern Viet Nam including the islands of Hainan and Taiwan. Agricultural areas close to protected forest areas are where many of the known records have been reported. It is likely that this species is far more widespread across agricultural areas than is currently documented.
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology: The larvae are found in muddy margins of small streams and irrigations ditches at the edge of forested areas or in open agricultural habitat.
Systems: Terrestrial; Freshwater
Threats [top]
Major Threat(s): Discharges of water rich in organic matter discharge from fish culture ponds and organic waste from domestic and agricultural sources are responsible for poor water quality in many stream and irrigation ditches, which would otherwise be suitable for this species. But, given the huge area available containing suitable habitat, across much of tropical southern China this species is not considered to be threatened
Conservation Actions [top]
Conservation Actions: Improved regulation and pollution control of discharges, containing high levels of organic matter, to small water courses in agricultural areas would significantly benefit this species.
