There are only a couple of IDs I need to question.
1) Benbowia is placed as a subgenus of Stauropus in Schlintmeister's Moths of Thailand, Volume 5, 2007. The species you mention is not, as far as I am aware, found in Thailand. It looks, very much, like Stauropus virescens, which is certainly found in the area of Nam Nao.
2) The Metanastria species you mention is only found in the far North of Thailand (Chang Mai area). It is much more likely to be the widespread Metanastria hyrtaca. The size of the cell spot also indicates that species.
The Syntypistis species are very difficult to ID from photos alone. Indeed, Schlintmeister has advised me, for several of my photos, just to put 'Syntypistis sp.' as you have done. I suggest you keep it as it is.
I look forward to more moths from your travels.
