Central American orchid experts? Oncidium (Lophiaris, whatever) ID question

[kentuckiense]

Hello everyone!

My girlfriend just arrived back from Belize and showed me some photos of an orchid she found. After getting over being jealous of her trip AND her getting to see orchids in-situ, I sat down with Orchids of Guatemala and Belize by Ames and Correll. It keyed out pretty well to Oncidium luridum (Lophiaris lurida), one of the mule-ears. Photos online look pretty good, too. Do any of you have better ideas for what the identity could be? I'm not familiar with this group at all so I don't really know if there are other similar species.

I can post the full-sized photos if needed.

Aaaand apparently Kew accepts this one as a Trichocentrum.
