This is a primitive spider in the Infraorder Mygalomorphae, a group that includes Tarantulas and Trapdoor Spiders. Your individual does not look hairy enough to be a Tarantula, so we suspect it is a Trapdoor Spider. We did try to locate matching images online with no luck, though we searched for both Tarantulas and Trapdoor Spiders in Peru.
Update: Linothele uniformis
A special thanks to Cesar Crash of Insetologia who wrote in identifying this Mygalomorph as a Funnel Web Spider, Linothele uniformis, and providing this link to Science Press.
