[3] Its scientific name is Plecturocebus aureipalatii,[2] the specific epithet meaning "of the Golden Palace", in reference to GoldenPalace.com, an online casino.

The casino paid US$650,000 to have the species named after it, with benefits going toward the nonprofit organization that maintains the park where the titi was discovered.

Preliminary studies indicate that the species is not endemic to Bolivia, with habitats that may extend to the south of Peru (at least to the Tambopata River).

[1][5] The Madidi titi has orange-brown fur, a characteristic golden crown, a white tip to its tail, and dark red hands and feet.

Rather than choosing a name themselves, Wallace, his team, and WCS auctioned off the naming rights to raise funds for FUNDESNAP (Fundación para el Desarrollo del Sistema Nacional de Áreas Protegidas), the nonprofit organization that maintains Madidi National Park.
