It seems to be a species close to C. sinicum or C. zeylanicum, but I cannot understand if the pronotum bears only a discal ridge at base or another ridge at each side.
In this case, the most similar species is Ceresium sinicum sinicum White, 1855. It is also present in Thailand but it has lighter legs in the only photos I have found in the Web.
Thailand: Ceresium cf. sinicum
