Wildlife Spotting

Belo achado! Nice Spotting!

Fantastic shot!

I think it's definitely safe to place it in the Avicularia genus—which specific species, however, is starting to get tougher, hehe. A straight up AviAvi is, I think, the most common, but they are also a bit "thicker" in the legs. It's hard to see, but the abdomen may have similar coloration to the Avicularia avicularia. This image-link of a geroldi looks almost exactly like the one at your lab: http://www.exotic-animals.org/pajki/slike_pajkov_nasih_uporabnikov/niko/Avicularia_Geroldi/Avicularia_Geroldi2.JPG

I suggest the geroldi due to its coloration and location. However, the prosoma looks to be a bit iridescent which might suggest it is a young Avicularia metallica (a rather docile, timid tarantula), but they are found in Columbia… perhaps someone's pet that escaped?
