We owe a lot to Jakob Isler - such a wonderful series of ( mostly) oncidium inter-generic crosses...think of Nelly Isler, Hansueli Isler, Stefan Isler, among maybe twenty five more...although there have been no more this century ( apart from a phalaenopsis, and I don't count florists phallys as orchids...)
And of course we owe to the meristemmers who make them available to us.
Your plant is one that hasn't crossed my radar ... when it does I shall swoop on it.
