The 21st July 2018, during one of my (few) explorations in my home island of Koh Phangan (Suratthani-Thailand), at about 9am at 300 mt altitude, I spotted a small, a bit battered, Deramas while sunbathing close to a stream in an opening of the forest. Quickly I took a few shots and, being out of the National Park area, I managed to capture the butterfly (now it is being prepared to be analyzed by an expert). It is a female and is not similar to any other Deramas I've found myself or in the literature.



Here a composite illustration of the interesting species:



Deramas sp.

I hope in the future to find a male to have a better chance to correctly identify the species.
