I believe it may be Aliceara (formerly Goodaleara) Tahitian Dancer. Typical Oncidium care, slightly moist, moderate to moderately bright. I had one, and it was a good bloomer.
Looking at Aliceara Tahitian Dancer, that's a very close match. The ancestry from Oncidium sotoanum is easy to see. With any NoID hybrid you can never really be sure, but that certainly gets close enough to find abundant growing instructions. In particular, I would say that it doesn't have much ancestry from the cooler growing side of the Oncidium alliance, so intermediate to warm conditions are probably good.
I agree it looks like Tahitian Dancer. The manufacturer (Inca Orchids) has a list of the hybrids they sell on their website and one of them was Tahitian Dancer. I thought it was the closest match. You must know your orchids well White Rabbit!
I will treat it like an Oncidium but with less light. I don't know why they put Odontoglossum on the tag but from what I am reading the care isn't that similar to an Odontoglossum.
I repotted it even though it was in bloom. It was growing in a very broken down medium that resembled soil. In the centre I found a plug of ?moss. The roots were not that great. Not rotting but extremely short. I used the Orchid Focus mix which is a mix of bark and coconut. I thought it might be a bit coarse for this orchid, but the other "Orchid" mix I have is garden centre style "soil" and I don't like my orchids in that with the exception of my Miltoniopsis (but even then use Orchid Focus mixed into it to improve drainage).
