No, I think it is rather Aristobia horridula (Hope, 1831).

Thx Xavier :)
There seems to be hairless scapi, that's why I thought it's freneyi. I can see something at the right scapus, but I'm not sure, because of the poor photo quality. The left scapus looks definitely hairless to me.

Yes, not easy. For me A. horridula has some hairs on the inner side of the scape apex, (difficult to see on the picture), but A. freneyi does not have such long tufts of hairs on the elytra (as visible on the picture).

The review by Jiroux & al (2014) based mainly on the tufts of hair on the antennae has always left me in doubt: I have Aristobia cf. approximator with 1, 2 or 3 tufts of hair...The same problem arises with scape hair:

For the specimen in question, what about the hairiness of the elytra?

I strongly think that this revision should be revised...

Hello forum,
so, the scapi definitely are hairless - the small shadows at the right scapus are due to the poor photo quality (done with a mobile phone).
And the elytra definitely have clusters of hair.

Unfortunately at the time of sighting my wife and I were in the arduous process of building our house here in Thailand, so neither I had the equipment for collecting beetles nor the time.
I read that a host for A. freneyi is Butea monosperma*, and since we're living outside of the villages in the middle of rice fields, there are some of this trees around our area.

Thanks to all and best regards from Thailand,
Chris
