Level 1 — Absolute Beginner
Scientists found a new kind of monkey in Africa. It lives in the rainforest of the Democratic Republic of the Congo, a country in central Africa.
The new monkey has a scientific name, Colobus congoensis. Local people call it 'likweli.' It has bright orange lips and grey fur near its cheeks. Its body is covered in soft black fur.
This is a very special discovery. It is only the fifth new monkey species found in Africa in the last 75 years. Scientists used DNA tests to prove it is truly a new species.
The monkey only lives in a small area of forest. Scientists are worried about it because people are cutting down trees and hunting animals there. They want the monkey to be protected.

Level 2 — Elementary
Researchers have identified a previously unknown species of monkey living in the rainforests of the Democratic Republic of the Congo. The species, named Colobus congoensis and known locally as 'likweli,' stood out immediately because of its striking appearance.
The monkey has conspicuous orange lips, slate-grey cheek patches framing dark eyes, and a coat of silky black fur, with a distinctive white patch near its tail. It also has a low, roaring call that is different from related species in the area.
Published in the journal PLOS One, the discovery is only the fifth new monkey species described in Africa over the past 75 years, making it an especially rare event in primate research. Genetic and physical analysis confirmed that likweli split from its closest known relative between four and five million years ago.
The species is currently found only within a relatively small range of roughly 1,700 square kilometers. Because of ongoing habitat loss and hunting pressure in the region, researchers are recommending that likweli be given endangered conservation status as soon as possible.

Level 3 — Intermediate
A team of researchers has formally described a previously unrecognized monkey species inhabiting the rainforests of the Democratic Republic of the Congo, publishing their findings in the journal PLOS One. The species, designated Colobus congoensis and referred to locally as 'likweli,' distinguishes itself through a striking combination of conspicuous orange lips, slate-grey cheek patches framing dark-rimmed eyes, and a silky black coat accented by a white patch near the tail.
Behaviorally, the species is further set apart by a distinctive low, roaring vocalization that differs markedly from calls produced by its closest regional relatives. Genetic and morphological analysis places its divergence from its nearest known relative at between four and five million years ago, indicating a long, independent evolutionary trajectory rather than a recent offshoot.
The description marks only the fifth new monkey species identified in Africa over the past 75 years, an exceptionally rare occurrence in contemporary primatology that underscores how much remains undocumented even in well-studied regions of the continent. Likweli's known range is currently confined to approximately 1,700 square kilometers of forest.
Given the combination of a restricted geographic range and mounting pressure from habitat destruction and hunting, the research team is recommending that likweli be formally classified as endangered, a designation that would afford it legal protections and prioritize conservation funding before its already limited population comes under further strain.

Level 4 — Advanced
A research team has formally described a hitherto unrecognized monkey species inhabiting the rainforests of the Democratic Republic of the Congo, publishing its findings in the journal PLOS One. The species, designated Colobus congoensis and known locally as 'likweli,' is distinguished by a striking morphological profile, conspicuous orange lips, slate-grey cheek patches framing dark-rimmed eyes, and a silky black coat accented by a white perianal patch, that sets it apart at a glance from congeneric relatives.
Behaviorally, the species is further differentiated by a distinctive low, roaring vocalization diverging markedly from the calls produced by its closest regional relatives. Integrated genetic and morphological analysis situates its divergence from its nearest known relative at approximately four to five million years before present, a finding indicating a protracted, independent evolutionary trajectory rather than a recent speciation event.
The description constitutes only the fifth new monkey species formally recognized in Africa over the past 75 years, an exceptionally rare occurrence within contemporary primatology that underscores the extent to which cryptic biodiversity persists undocumented even within comparatively well-surveyed regions of the continent. Likweli's currently documented range is confined to approximately 1,700 square kilometers of forest habitat.
Given the convergence of a narrowly circumscribed geographic range with escalating anthropogenic pressures, namely habitat degradation and hunting, the research team is advocating for likweli's prompt classification as endangered, a designation that would confer legal protections and prioritize conservation resources before an already constrained population faces further demographic strain.
