Re: Red Vittatus?
I helped write the vittatus TMP and the reason we recommended maintaining two separate populations is because they were introduced into the hobby from two different origins (even if one of those origins was Europe) without any solid information about whether or not they were from the same population (if you check the IUCN website, there is a possibility there are two populations). Also, it's possible that clinal variation is a possibility as some frogs seem to have a speckled pattern between the dorsal stripes. Whether this is variation within the population, clinal variation or different populations, we have been unable to determine for sure.
Using colors to differentiate the populations is misleading (as has been said) because I have seen different color/hues of striping within the same line simply because of supplementation and diet. I believe this was used in at least the first draft of the DB care sheet--whether or not they are still listed that way, I'm not sure. This is why we went with the 'wide-banded' and 'narrow-banded' labels and, although they are not the best descriptors...they are better than using coloration.
As EricM said above, I wonder how much these have actually already been mixed in the past. I have the wide-banded line that I know have not been mixed with any other frogs, but am not sure how similar/different they are than the narrow-banded frogs. It's quite possible they are from the same population or were collected in the same general area, but when considering genetics and captive population management, we could only work with absolute information and details...hence the reason in the TMP we had to recommend that they be managed separately.
