I hate linking to wikipedia, but they have all of the important links on their page too:

http://en.wikipedia.org/wiki/Leptotyphlops_carlae

This species was already "discovered" and the natives knew about it for a long time. We have to stop claiming that as soon as a western scientist reaches a jungle that he or she is the first person see a species. it's taken nearly 500 years for people to finally start believing that Columbus didn't discover America.

Cool snake though.
