This is the first record from Thailand. The first discovery was taken photo by Antonio Giudici on 4 March 2020 in Umphang Dist., Tak.
The butterfly was found around small stream in montane forests at moderate elevations and appears to be a very local species. Males are occasionally observed mud-puddling along stream banks and at puddles.
