The medium-sized monkey with an orange-colored patch around its nose and mouth, known locally as Likweli, joins a very short list of newly identified African monkey species.

It is only the fifth new African monkey identified as a new species in the past 75 years.

More than 5 percent of the species is estimated to have been lost when a climate-fueled storm unleashed torrents of water, mud and debris.
