A few Indonesian orchid hunters have shared pics on Facebook recently. To me, it looks intermediate between tonsum and javanicum. Thought it might be a natural hybrid but they say that the population is pretty large (hundreds of plants at least).
Yes Tim that is it. It is new. I would suggest hybrid although the reports do say it is a large group of plants that are isolated from the potential species that would form it. Some have already been in trade and I believe there is more than one in that area that has been shown on FB.
If that is typical, the proportions of that flower don't suggest a hybrid unless one parent has proportionally even longer narrower nearly horizontal petals... rothschildianum? I don't think so. If it is a large disjunct population it appears to be something new.
