The geographic range of the Leontopithecus caissara is limited to about 17,300 hectares in southeastern Brazil (Massicot, 2001). It was first discovered in 1990 and was thought to exist only on the small island of Superagui in the state of Parana. It has since been observed on the mainland in the adjacent state of Sao Paulo (Kleiman and Mallison, 1998).
