The orange hail from near Chumanza (or Shumanza depending what map or road sign you refer too) and the orangehead from further south between Nuevo San Martin and Polvora. The north south distribution of this species seems to be a gentle transition from Bright yellow in the North, to bright red in the south. Further north from Chumanza near Camapanea and Juicungo you have the really nice yellow populations, and closer to Tocache at the southern extreme they are bright red, not orange, red. The stuff in between is varying shades of orange. You have about - if memeory serves me correctly because it has been a long time since i looked at a map of the region- only about 40 km in a straight line between the orange and orangehead sites where we collected founding stock from in 2005 and 2006. Though the populations are separated now, they probably, or at least the orange ones in question, were probably once part of a larger near continuous population only separated in the last few hundred years due to human interference.
Anyways, I have never seen a huge variation in either of these populations in the wild, nor from all I have bred where one comes out and looks like the other, but I sure won't say it is impossible. I have only seen a few dozen at most of the Chumanza frogs during the last decade in the wild, as they have always been hard to locate, so there could be more variation in that population than I have encountered.
Anyways its easy to imagine a mix up with the two forms, as a they are similar, and thanks to me, too confusingly named.
