Monkey with orange lips identified as newfound species

Orange-Lipped Primate Revealed as Previously Unknown African Monkey Species

A Remarkable Discovery in the Congolese Rainforest

Monkey with orange lips identified as newfound – Scientists have officially recognized a previously undocumented monkey species residing in the Democratic Republic of Congo. This remarkable primate, scientifically named Colobus congoensis, has captured attention for its striking orange lips and powerful vocalizations. According to research published Wednesday in the academic journal PLOS ONE, this represents only the fifth entirely new monkey species documented across the African continent during the past seventy-five years. Local communities refer to this fascinating creature as Likweli.

Researchers affiliated with Florida Atlantic University alongside colleagues from the City University of New York Graduate Center provided detailed descriptions of the animal’s appearance. The monkey possesses a lustrous black coat, elongated fur, and an impressive sweeping tail. Its face displays vivid orange-cream colored markings that create a distinctive appearance. Scientists noted that cranial, dental, and skeletal features clearly distinguish this species from all other African colobus monkeys currently known to science.

Physical Characteristics and Evolutionary Significance

Compared to its closest relatives within the Colobus family, this newly identified species is notably smaller in size. Adults typically weigh approximately fifteen pounds, which translates to roughly 6.8 kilograms. The researchers emphasized several unique physical attributes that set this monkey apart from similar species.

“It is distinguished by sleek, light-reflecting fur and dramatic facial features created by long black facial hairs and large folded ears,” said Florida Atlantic University in their official statement.

Kate Detwiler, who serves as an associate professor of biological sciences within FAU’s Charles E. Schmidt College of Science and led the study, expressed enthusiasm about the findings. She explained that this discovery fundamentally alters scientific understanding of how African monkeys evolved over time. The closest known relative to Colobus congoensis is Colobus satanas, which inhabits regions more than 1,200 kilometers away in west-central Africa. Despite this geographic separation, genetic analysis reveals that these two species split from a common ancestor approximately four to five million years ago. This represents one of the most ancient evolutionary divisions documented within the entire Colobus lineage.

The Journey of Scientific Documentation

The process of formally describing this new species commenced in 2008, when researchers conducting fieldwork in east-central DRC captured photographs of an unusual primate. A decade passed before scientists obtained clearer observations. Between 2018 and 2022 alone, they recorded one hundred fourteen separate sightings of the animal.

Establishing that this represented a genuinely new species required multiple lines of evidence. Researchers examined genetic material, conducted extensive anatomical comparisons, and incorporated local ecological knowledge into their analysis. Christopher Gilbert, a professor of anthropology at both the CUNY Graduate Center and Hunter College, emphasized the rigorous standards required for such discoveries.

“When a potential new species is discovered, the evidence has to be overwhelming,” said Gilbert in the CUNY statement. “We analyzed museum collections and comparative datasets, examining skulls, pelts, and skeletal anatomy alongside specimens from known African colobus monkeys. Those comparisons allowed us to demonstrate conclusively that Colobus congoensis represents a distinct species.”

Conservation Challenges and Future Protection

Despite the excitement surrounding this discovery, conservationists have raised concerns about the species’ future. The documented sightings span a relatively limited area of approximately 1,700 square kilometers, or 656 square miles. This restricted geographic range makes the population particularly vulnerable to environmental threats.

“The researchers propose that Colobus congoensis be classified as Endangered because of its restricted range, habitat loss, and hunting pressure,” reads the CUNY statement. “Most of its known habitat lies within Lomami National Park, making protection of the region critical for the species’ survival.”

External experts have praised the comprehensive nature of the research. Alexander Georgiev, a senior lecturer in primatology at Bangor University in Wales who did not participate in the study, described the analysis as exceptionally thorough and convincing. He noted that discovering a monkey species unknown both to science and to local populations is quite rare.

“Finding a new monkey species that is not only unknown to science but is also little known to the people that live where it occurs is very rare and exciting indeed,” Georgiev told CNN on Thursday.

Georgiev highlighted an interesting aspect of the discovery: residents in only eight out of fifty-two villages bordering the species’ range could provide information about Likweli. This limited local awareness helps explain why the species remained undocumented for so long. The Congolese rainforest habitat where this primate resides covers an enormous area, and scientists have explored only portions of it thoroughly.
