Well, it looks like you got the 2 agassizii-complex species found in the Rio Tefé. The first males probably are (if we believe the location name) the Tefé population of the holotype form of A. agassizii. The last photos appear to be A. sp. Tefé males. Your main problem IMHO is determining which females belong to which species. They are so similar that I doubt that anyone could separate them (other than the fish themselves). I know that I can't.
