This looks like Eria acervata. I need closeup of flower from front to confirm.

Looks like but difficult to confirm with these images !

I do not have any closeup(high resolution) images of this species. I had already collected this species from wild and planted in our  departmental orchidarium. If it blossoms next session I will definitely upload it.

Yes most likely Pinalia acervata.
