Phymatostetha borneensis - Butler 1874

Photo taken at Wang Lung, Nakhon Si Thammarat Prov., Thailand on 5 February 2018.
This is a new record for Thailand.
The species found in the forests of peninsular Thailand, and seems to be quite rare. It reaches its northernmost part of its range in Thailand. A single record from Nan in October appears to be an extreme extension to the range and is rather puzzling.
The species is similar to P. circumducta, but differs by having red markings and a single apical spot.
