Serra do Ramalho

The caves of the Serro da Ramalho karst area in the municipality of Serra do Ramalho, a municipality of the same name in southwestern Bahia State, Brazil, have been explored since the early 2000s. The several large cave systems present a great biospeleological potential. Newly discovered species include the first troglobitic Amblypygi recorded for Brazil, "Charinus troglobius" , an eyeless harvestman ("Giupponia chagasi" ), an as yet undescribed genus of spiders (Ochyroceratidae), and a species of catfish ("Rhamdia enfurnada" ).
