It sure looks like that but personally I hesitate do to identifications like this based on the the internet. To many wrongly labed pictures (also on IOSPE). Try to find a book where there is reall descriptions.
Neither do I. I had a look at all the species at IOSPE and the most similar to me was not antennifer but IOSPE PHOTOS . This due to shape of the lip and the column. But like I said identification over pictures on the internet is difficul with any orchid. Best you can do is hope for some specialist to show up but with this genus I'm not confident on this happening.
Part of the problem with the pictures on IOSPE is that the data given doesn't match - this is from Peru and the one you've shown is from Ecuador - could still be from Peru, but that isn't stated.
