Recent molecular work in our lab (Kyle Summers lab) shows that D. duellmani as it was originally described does not appear to be a valid species. Rather, it is really a striped form of reticulatus, which goes well with what other people have been saying. The Tamshiyacu-Tahauyo 'duellmani' (with yellow sides) is actually not related in any way to the true nominal duellmani. It is much more closely related to the fantasticus group. Mark is correct in saying this frog is currently being described as a new species. As far as amazonicus goes, as far as I am concerned this species is BS. The Iquitos-region ventrimaculatus group is so widely variable that it is more than likely we are just looking at variation among a freely-interbreeding population. For example, coloration/pattern (full-Y mark, nose spot, yellow, orange, red) motifs are not discrete but continuous, which seems to indicate much mixing. A melting pot for vents if you will. But this is conjecture and should be cleared up within the foreseeable future.
