bonobo

n. pygmy chimpanzee, small species of chimpanzee native to Zaire (listed as a threatened species)

The Bonobo (Pan paniscus), until recently usually called the Pygmy Chimpanzee (and less often the Dwarf or Gracile Chimpanzee), is one of the two species making up the chimpanzee genus, Pan. The other species in genus Pan is Pan troglodytes, or the Common Chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the Common Chimpanzee.
