|Alta Floresta Titi|
The Alta Floresta titi (Plecturocebus grovesi), is a species of titi in the Pitheciidae family. It is endemic to Brazil. It was described from the municipality of Alta Floresta in the state of Mato Grosso.
It is a member of the Eastern Amazonian clade of the red-bellied titi (P. moloch) group, and is the sister taxon to the clade containing the red-bellied titi and Vieira's titi (P. vieirai). It can be distinguished from other species in the P. moloch group by the combination of its agouti dorsal parts, the bright red-brown venter, the entirely black tail with a white tip, and the light yellow fur on the cheeks.
