It was a tentative ID.
Since you have the book I thought you might check on it.
It looks too much like Orgyia with the usual markings enhanced with white.
Since there are only a few species there it might even be O. postica itself.
As for the others, I am afraid, no match found.
TL Seow: Cheers.
PS. Do you know of a species called Orgyia albofasciata. Schintlmeister 1989, TL Thailand.
albofasciata means marked with white fascias (bands or lines) & would seem to fit this one nicely.
