Hello JP,
Well you have the basics of their biogeography correct, I will break
it down a little more.
Pepperi was a species discovered in late 2005 along the western flank
of the Cordillera Azul. When we first discovered these frogs, we
thought they were southern population which represented a range
extension of A. bassleri. In these mountains it is distributed in mid
altitudes with a north south distribution running from aproximately
Campanea in the north, to near Tocache in the South. The northern
populations are indeed yellow, and right near Tocache you have
wonderful red form.
Those in between are orange to red orange.
The "orange" Is different than the orange head in a few ways. First
within the orange population the orange is often a subdued yellow
orange, and distributed in more robust blotches of colour on the head.
The lateral stripes often closely match the head coloration.
Further south we have the orange head. generally these are a much
more vibrant orange with less colour dorsally, more concentrated on
the head. The bright yellow lateral stripes contrast nicely the deep
orange head. The two frogs side by side are quite different.
Unfortunately the pics on my site are not good representations of the
species.
The Yellow Gold is from Campanea, the northern tip of the range, and
these are deep yellow to gold coloured ones. Overall, darker frogs
than the other populations.
The Abiseo are gorgeous with genourous canary yellow on the head and
dorsum, complimented by bright blue legs.
All populations are closely associated with gentle forest streams,
though running water is not required to breed them in captivity.
The "rood" that are in the us are the same as OrangeHead, and
actually, the founding stock of Rood were animals we exported to
Holland, which were then re-exported to the US. In Europe most orange
frogs are considered red, hence the name change in Europe to "Rood"
Ameerega are the most underappreciated animals in the hobby, seems you
have good taste sir!
kind regards,
Mark
