Geographic Range [top]
Range Description: Bayadera hyalina is known from Meghalaya in India (e.g. Laidlaw 1917, Fraser 1934, Lahiri 1987) and from Doi Inthanon in Chiang Mai in northwest Thailand (e.g. Hämäläinen and Pinratana 1999). It is likely to occur in Myanmar, and should be looked for there. Records from China appear to be misidentifications of other Bayadera species (e.g. Wilson and Xu 2007).

Population [top]
Population: There are not many published records of this species. It occurs with some regularity on Doi Inthanon in Chinag Mai, and there are a number of records from Meghalaya. It is likely to be under-collected, as it is not a very conspicuous species, and appears to be extremely wary.
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: Unknown
Habitat and Ecology [top]
Habitat and Ecology: Breeds in streams in montane forest.
Systems: Freshwater
Threats [top]
Major Threat(s): This species habitat is certainly threatened by clear-felling, although it may be sensitive to lesser degrees of disturbance.
Conservation Actions [top]
Conservation Actions: Fresh data is needed from Meghalaya, and searches should be made in adjacent areas of India and in Myanmar. The known locations in Chinag Mai are in a national park, but see Hämäläinen (2004) for an account of practices detrimental to odonate populations in National Parks in Thailand. Conservation measures for this species will centre around the establishment and proper management of protected areas in mountainous areas.
