Elymnias chrysalis, and looks like being Elymnis panthera, which is found in Singapore and India, so in my eyes also in Thailand. Please, verify and check other Elymnias sp., the details might be subtle. Brown color is not usual? But remembering the different colors in Papilio machaon chrysalis, it might be possible that you just have found a brownish variant?
Something for Keith or earlystages to take a look at...
