I need this information in order to identify a spider that eats scorpions.
Thanks, but i need dicotomic keys to identify a specie in particular
What is the genus do you suspect the species belongs? There are several old but good monographs of several genera by Herbert W. Levi. Also, I have several monographs and keys, but I'd need the genus in order to send you some material.
Latrodectus are known to prey on scorpions. I would start by looking into it and related genera such as Steatoda.

I am not sure where you are in your process, but thought I would add that the American Arachnological Society has a book it sells "Spiders of North America - An Identification Manual" which is very useful for it's intended geographic region, but might provide a possible ID for the genera of Columbia, or close. While the link in the Tolweb does not work, you might contact the website developer to see if you can reestablish contact.
