Phymatostetha stalii - Butler 1874

Photo taken at Mae Kampong, Chiang Mai Prov., Thailand on 12 October 2014.
This is a new record for Thailand.
The species appears to be restricted to the northern montane areas of Thailand, and does not seem to be rare, as it has been found on many Chiang Mai mountains.
