Just FYI - mine came from Ecuagenera. Full name on tag is Prosthechea fragrans Villaseca. The pic is from the day I got it in early August and it seems to be doing pretty well.

Based on Carl Withner's book, there are subtle differences in the shape of the upward pointed lip (Anacheilium, which the group gets its name), lip patterning, as well as the column shape, leaf and p-bulb morphology. Though, it mentions that many species are variable, making it even more difficult to differentiate.

Minor differences to the hobbyist!
