An international team of scientists, including Yale researchers, has described a new Colobus monkey species inhabiting high forest canopies in the Democratic Republic of Congo ( DRC ). It is just the fifth new species of African monkey discovered in the past 75 years. The species, Colobus congoensis , is a rare and cryptic monkey largely unknown even among people living within its range. But those who are familiar with the small, black monkeys — an arboreal creature marked by distinctive orange-cream patches around their mouths and noses — call them “Likweli,” which the researchers recommend remain the species’ common name.  The identification of Likweli as distinct from other Colobus monkey species is supported by evidence drawn from its physical traits, genetics, and vocalizations.
