OK - now I got it.

I have tried researching Orgyia albofasciata, but can't find any further information, than that it was indeed described from Thailand by Schintlmeister in 1989. When I try googling Schintlmeister, 1989 no articles concerned with Thailand show up. Do you have the full reference to the article, I may try to get it. The specimen on my photo does have whitish lines, so name seem to fit

thx again

Edit: I am now (from 5 minutes ago) connected to Schintlmeister on Research Gate, but he has only his newer works there. Quite generous though the whole MoT vol 5 (Notodontidae) is available for download in excellent quality including plates.
