Frederico,
Bem! I am going to try and attach a thumbnail of my coelogyne stricta (excuse the botrytis). You will notice thta although the colour of the lip markings differ in your photo, the photo in orchid species and my photo (as well in claytobn's book) they all have two prominet lamellae (ridges) in the coloured area. Your plant should have tightly overlapping bracts below the first flower. check it out.
