Geographic Range [top]
Range Description: M. t. tibetanum is known from northwest Myanmar and central Sichuan, China (Yu and Bu 2009). M. t. australe is known from central Sichuan to Yunnan and northern Myanmar (Yu and Bu 2009). A record in Schmidt (1964) of a male from Hejunta in Yunnan might be of either subspecies. There is an additional record of M. tibetanum from Chiang Mai, Thailand (see Taxonomic Note). From the known distribution, it is likely to occur also in Laos and northern Vietnam. The only recent (e.g. within the last two decades) records are from about seven locations in Yunnan and Sichuan, and from Doi Inthanon in Thailand. Records from Shaanxi and Zhejiang refer to M. yachowensis.

Population [top]
Population:
Although not many specimens of this species have ever been collected, given the available information on habitat and distribution, it is likely to be quite common, just under-recorded.
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology:
Kalkman (2008) provided observations on the habitat of M. tibetanum, noting that at Emei Shan in Sichuan it was found “along a small path bordering a larger, at least partly sunny, rocky stream at 1,400-1,600 m. … it was not clear if this stream or if the nearby runnels served as larval habitat” and at Wolong in the same province “along a partly channelized, stony brook less than 1 m wide and 40 cm deep. This largely unshaded brook flowed through agricultural fields.” These observations suggest strongly that M. tibetanum can survive in disturbed habitats.
Systems: Terrestrial; Freshwater
Threats [top]
Major Threat(s):
Based on the habitat information available it appears unlikely that M. tibetanum faces any serious threats at the present time.
Conservation Actions [top]
Conservation Actions:
No conservation measures, beyond further research, appear to be need for M. tibetanum at the present time.
