Cosmoscarta brevis - Schmidt 1910

Photo taken at Doi Suthep-Pui, Chiang Mai Prov., Thailand on 11 October 2017.


This is a first record of the species from Thailand, having previously thought to be endemic to Myanmar (Bago province).
The species matched the type description in every way EXCEPT that there is no mention of the tiny forward white spot. Spots can be variable and are not diagnostically reliable.
This appears to be a very rare montane species in Thailand.
