    Definitely Osteocephalus sp., based on general appearance and also those crazy radial lines in the eyes. Posted 6 years ago

    Could be Osteocephalus planiceps -- check out known distribution in Colombia at https://www.researchgate.net/publication/228627011_Osteocephalus_planiceps_Cope_Amphibia_Hylidae_Its_distribution_in_Colombia_and_significance Posted 6 years ago

      Hmm, Inírida is significantly north of the distribution shown in that paper, though the light stripe on the upper lip, radiated eye lines, and general appearance all seem like a good match for O. planiceps. Maybe there's a closely related Osteocephalus species in that part of Colombia? Posted 6 years ago

        Hmm, amphibiaweb.org doesn't list O. planiceps in Colombia at all. Maybe the specimens described in that 2008 paper have since been moved to some other Osteocephalus species? Biology is hard!

        Osteocephalus taurinus seems like another good candidate. In fact, that is the only Osteocephalus species shown in the Inírido area in this 2012 overview of the genus: https://www.researchgate.net/publication/255993637_Systematics_of_spiny-backed_treefrogs_Hylidae_Osteocephalus_An_Amazonian_puzzle

        I'm going with O. taurinus.         Posted 6 years ago

          So hard indeed, thanks for all the research!

          Do you think the amount of bands on the legs matters? Or is this just a random variable thing? I'm seeing less bands on Osteocephalus taurinus compared to planiceps, and that's about the only difference I see visually.           Posted 6 years ago

            I think the banding is variable in both species. O. taurinus gets larger, and has a somewhat blunter snout, and doesn't always have a light stripe on the upper lip (but it sometimes does). But the more important criteria here is that O. taurinus is known from this specific area and O. planiceps is no longer considered to be present in Colombia. Posted 6 years ago

              Thanks once again, I'm going to settle it on O. taurinus as tentative species. Posted 6 years ago
