Hi Aaron. This is in the same location as the other sightings of C. seminuda and was recorded only 4 days before I was shown the site by Tony and Jean. Did you also see it with them? Or even show it to them?
Given the callus doesn't extend all the way to the tip of the labellum, as it should in C. trilabra, I would think this is C. seminuda. The callus only extends about 2/3rds of the way down the labellum in C. seminuda.
