A new species of monkey with distinctive orange lips and a deep roaring call has been identified in the Democratic Republic of Congo (DRC).

Colobus congoensis, known to local people as Likweli, is just the fifth new monkey species scientists have identified in Africa in the last 75 years, according to a study published in the journal PLOS ONE Wednesday.

The monkey has a glossy black coat, long fur, a sweeping tail and striking orange-cream facial markings, said researchers from Florida Atlantic University (FAU) and the City University of New York Graduate Center in statements on Wednesday.

They added that the species has “distinctive cranial, dental, and skeletal characteristics that separate it from every other known African colobus monkey.”

It is also smaller than related Colobus monkeys, weighing around 15 pounds (6.8 kilograms). 

“It is distinguished by sleek, light-reflecting fur and dramatic facial features created by long black facial hairs and large folded ears,” said FAU.

“The discovery of Colobus congoensis is reshaping our understanding of African monkey evolution,” said study senior author Kate Detwiler, an associate professor of biological sciences in FAU’s Charles E. Schmidt College of Science.

“Its closest known relative is Colobus satanas, found more than 1,200 kilometers (746 miles) away in west-central Africa,” she said. “Yet our genetic evidence shows the two species diverged roughly 4 to 5 million years ago, marking one of the oldest known evolutionary splits within the Colobus lineage.” 

The process of describing the new species began in 2008, when an unusual monkey was photographed by researchers working in east-central DRC. Ten years later, they made a clearer observation, and went on to make 114 sightings from 2018-2022.

In addition to its anatomy and field observations, researchers also had to study the monkey’s genetics and use local ecological knowledge to prove that this was a species that had never been described before.

“When a potential new species is discovered, the evidence has to be overwhelming,” said coauthor Christopher Gilbert, professor of anthropology at the CUNY Graduate Center and Hunter College, in the CUNY statement.

“We analyzed museum collections and comparative datasets, examining skulls, pelts, and skeletal anatomy alongside specimens from known African colobus monkeys,” he said. “Those comparisons allowed us to demonstrate conclusively that Colobus congoensis represents a distinct species.”

However, there are some conservation concerns for Likweli, given the fact that the sightings were made across a range of around 1,700 square kilometers (656 square miles).

“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.” (CNN)

A mysterious disease with flu-like symptoms has killed dozens of people in the Democratic Republic of Congo, according to health officials there.

The unidentified illness has killed 79 people and sickened 376 as of Tuesday, according to the country’s Ministry of Public Health, Hygiene and Social Security.

In a statement on X, the ministry said the disease was of “still unknown origin” and had been detected in Kwango province in southwestern Congo.

Reported symptoms include fever, headache, nasal congestion, cough, difficulty breathing and anemia.

Local authorities told Reuters and The Associated Press that the death toll may be as high as 143.

The health ministry said that the remains of anyone who has died after experiencing similar symptoms should not be handled without the involvement of authorized health authorities, and it asked people to report any suspicious illnesses or unusual deaths. The office also advised people to avoid mass gatherings and observe basic rules of hygiene, including washing hands with soap and water.

Emergency public health officials have been dispatched to the region, according to the ministry.

The World Health Organization told NBC News that it is aware of reports of an unidentified disease and is working with local authorities.

“We have dispatched a team to the remote area to collect samples for lab investigations,” WHO spokesperson Tarik Jašarević said in an email.

The U.S. Centers for Disease Control and Prevention, which has an office in Congo, said it is aware of the situation and is providing technical assistance to a rapid response team dispatched by a local emergency operations center.

Anne Rimoin, an epidemiologist at the University of California, Los Angeles, who has worked in Congo since 2002, said diagnosing the illnesses may be complicated by limited health care infrastructure and because of underlying health issues in some of the population, including malaria and malnutrition.

“I think it’s really important to be aware of what’s happening, and I think it’s also really important not to panic until we have more information,” she said.

“It could be anything,” she added. “It could be influenza, it could be Ebola, it could be Marburg, it could be meningitis, it could be measles. At this point, we really just don’t know.”

Dr. Abraar Karan, an infectious disease physician at Stanford Medicine, said the outbreak “does raise alarm bells” because of its location. Interactions between humans and wildlife in Congo increase the risk of a pathogen spilling over from animals, he said, and “many animal infections that transmit from animal to human can cause pretty severe disease.”

To identify the disease, Karan said, local health officials will start by screening for common illnesses like flu or malaria, before testing for less common pathogens. If all those tests are negative, officials may genetically sequence tissue, blood, mucus or bone marrow from infected people, he said. 

At the same time, international teams on the ground will collect information about what risk factors sick people have had in common and who they’ve been in contact with, said Amira Albert Roess, a professor of global health and epidemiology at George Mason University.

“I think pretty quickly we’ll start to have an answer as to what this is,” Roess said, noting that there have been “a lot of deaths, especially in such a short amount of time, with the same types of symptoms.” (NBC)
