Beautiful tongue, but it does not speak its name........

I had the good fortune to be able to buy a collection of plants that were in desperate need of some care and fertilizer, a few months ago. They do not stop rewarding me with new flowers now. Most are familiar or correctly labelled, but some are quite enigmatic.
I have one that looks like a Laelia from Espirito Santo or Minas Gerais in Brazil. But which one could it be? I have gone through Withner and many websites, but the closest i got was with the help of the beautiful pictures Mauro Rosim posts on Flickr. Is it or is it not a Hoffmanseggella caulescens aureoglossa? Or perhaps a Hoffmanseggella reginae?
It was labelled Laelia gardneri and was kept without much remaining substrate when i got it. So it should be a bit more substantial when grown under better conditions. It could even be a lithophytic species. It stands ten inches and does not like excessive heat. We had a few days of 40C or 104F in August and that made it wither within a day or two.
