Scinax ruber — Two-striped Treefrog
Some other names for this species:
Common Scinax, Red-snouted Treefrog, Allen’s Snouted Treefrog
About half the references I've found for this species call it Scinax rubra, and the others call it Scinax ruber. S. ruber seems to be the current leader in this latin adjective gender competition.
Scinax ruber comes in a wide assortment of patterns and colors, just to make identification more interesting.
While most of our group was still enjoying the fine home-made rum at this tiny distillery along the river, Matt Cage, Kevin Messenger, and I were poking around for miscellaneous herps. Either Matt or Kevin uncovered this little treefrog, which Matt identified as Scinax ruber based on the faint traces of stripes down its back.
I believe that the larger, darker frog is an adult female Scinax ruber and the smaller, yellower frog a couple of plants away is an adult male Scinax ruber. I didn't wait around long enough to see whether they would ever meet.
This is quite probably the least interesting treefrog I saw in 2016. Also, my camera lens was fogged up at the time, so the colors and contrast are all off. Still, any treefrog is better than no treefrog at all.
