B tingabarinium can also be a very light orange...almost yellow...but it's not that one either.

The flower is very familiar but, off the top of my head, I couldn't give you a name. Hopefully the vendor will recognize it. Either way, it's very pretty.

Looks to me like its bulbophyllum Thai Spider ( which has medusae as a parent)

It is very cool. Good going.

I agree not pecten-veneris (of which tingabarinum is a synonym). Almost certainly a hybrid, possibly Thai Spider (medusae x gracillimum) as Jack said, or maybe Worayuth White Fang (flabellum-veneris x medusae). There are other possibilities, some likely unregistered, so unfortunately without more info from the vendor you can't put a definite ID to it. Nice, though, whatever it is!
