From 1986 to 1992, I surveyed the invertebrate fauna of twelve limestone caves from South Ribeira Valley (State of Paraná, Brazil). Associated to walls in the entrace zone live Enoploctenus and Blechroscelis spiders, Goniosoma opilionids, Strinalia crickets, Latebraria amphipyroides moths, and Culicidae and Sciaridae dipterans. In aphotic zone, occur Plato spiders, Daguerreia inermis opilionids, Pseudonannolene strinatii diplopods, Smicridea caddisflies and the aquatic crustacean Aegla paulensis. I found in both zones Ctenus fasciatus spiders. Paronella collembolans, Zelurus travassosi heteropterans, Cholevidae and Anthribidae beetles, Phoridae dipterans and Braconidae wasps. One of the most important energy sources in these caves is the hematophagous bat guano. Associated to the guano piles there is a fauna composed by psedoscorpiones, acarians, Katantodesmus diplopods, Acherontides and Paronella collembolans, Dissochaetus beetles and Phoridae dipterans. The cave fauna studied is similar to that Ribeira Valley of the State of São Paulo. The most expressive difference is the absence of some taxa very common in São Paulo caves, such as the Oniscidae and Styloniscidae isopods, Cryptodesmidae and Chelodesmidae diplopods. Endecous crickets, Tricommatidae harvestmen, Calamoceratidae caddisflies and Neoditomyia Keroplatidae dipterans.
