It is well possible, but not one I know a lot about. The only treatment I can find that refers to it is David Jone's field of ACT orchids so perhaps the aff taxon is not widely accepted.
@Tapirlord it gets a page in Lachlan's book from last year, but that's the only place I've seen it so far. Seemed a possibility as I can't figure out what this guy could be hybridised from!
