I wanted you to know that at least I have looked at your post, but I cannot help out with an ID, so that you do not feel as if your post had been neglected.
The same situation may have happened with the other members in that they are stumped as well, idk.
There are a lot of species of orchids that are still unidentified by science, particularly in the larger groups of orchids such as Bulbophyllum and Pleurothallids in general.
I'm sorry.
Congratulations on a rare find though!
