Excellent Nuwan, I had in mind it was not a moth but.... I find it in my large butterfly guide of Thailand and the images are even better than on wikipedia, although with the number of ssp it's hard to tell. It is ssp apicalis, first because of the size (ssp lilacinus is smaller) and because ssp liliacinus is only found on the Thai peninsula plus Malaysia, whereas ssp apicalis is found throughout Thailand, be it an uncommon species. Thank you very much, very fast solution and ID, great!
