Diasporus looks like a good ID for the genus. Could be D. gularis, or maybe D. diastema. I don't have any info about how to distinguish these two species. Posted 8 years ago

  Thank you. A general image search comparison does not leave me with any conclusions on which of the two is more likely, so leaving it at the genus level for now. Posted 8 years ago

    Where is Santa María? Google keeps thinking I mean "Santa Marta" instead. Posted 6 years ago

      Yes, I've been having the same problem for a long time. Check this example observation that is geotagged in Santa Maria by camera to see where in Colombia it is:

Hmm, revisiting this one, it looks much larger and more robust than either of the two Diasporus species mentioned. Do you remember how large it was? The truncated finger and toe pad discs are a good clue to its identity. Posted 6 years ago

Here's a good site (in Spanish) for amphibians in Colombia, including dot-locality maps for at least some of the species: https://www.batrachia.com/orden-anura/leptodactylidae/adenomera/ Posted 6 years ago

Hmm, now I've found a couple of photos of Pristimantis penelopus that look remarkably similar to your frog. See for example MHUAA 8111 on https://www.researchgate.net/figure/Phenotypic-variation-of-Pristimantis-penelopus-across-its-distribution-Localitites-are_fig1_315144996

That link is to an article talking about how varied in appearance this species can be, in case it wasn't already hard enough to ID any Pristimantis species.

Also take a look at figure 3-G in https://doi.org/10.15560/13.4.203

Too bad your photo doesn't show the heel clearly, so we could check for spikes like the ones visible in figure 3-G. Do you have any photos of this frog other than the two in JungleDragon? Posted 6 years ago

  That PDF is really useful! Pristimantis penelopus looks incredibly similar to me, and the distribution matches perfectly. I have 3 more photos from the same observation but they are more like failed shots with parts out of focus. They don't seem to reveal new information.
  
  Size is hard to estimate for me, I'd say mid-sized as not being a super tiny frog, but definitely not large either. In the range of 2-5cm would be my best guess.
  
  What are your thoughts on picking Pristimantis penelopus as a match? Posted 6 years ago

    Picking Pristimantis penelopus seems good to me. It might be some other similar Pristimantis, but that looks like a really good match. Posted 6 years ago
