They're Ranitomeya imitator intermedius from the Uhern line. They're pretty much identical to imitator chazutas except that we don't have any locale info to prove that's what they are.

I took the lid off and snapped a couple of pics of the small one with my iPhone.




I'll post some better pics tonight provided they don't go into hiding. I don't imagine they will as they've been exploring their shipping container non-stop since I got them.
