Is this not just Betta mahachai? They can live in brackish water and I have read from a few owners of them, that they prefer a bit of salt in their aquarium.
Last I heard most of their habitat had been turned into salt pans or something so they are nearly or are extinct in the wild.
Don't know why they are saying they are a new species if it is indeed Betta mahachai as they have been around for a while now. And I am pretty sure they can hybridise with anything in the splendens complex of bettas. Just not any of the other complexes.
Hybridisation is one of the factors that is threatening the purity of the true wild Betta splendens.
