No, not the same species as A. cf. hoignei (Arauca) = A. sp. Tame, etc. It appears to be a population of A. macmasteri, which is known to occur in the Río Tame, too. The true A. cf. hoignei (Arauca) shows a black edge above the red streaks in the caudal fin. These fish do not.
I understand you feeling about the macmasteri-complex. Until very recently it wasn't safe even for native collectors to collect in some areas of Colombia. Now that the area is more peaceful we are seeing more fish from the area - some known, but many are new. I think things will become even more complicated for a while.
