Découverte d'une espèce de singe inconnue en Afrique (VIDÉO)

In Democratic Republic of Congo’s forests, scientists have officially recognized a previously unknown species of monkey, marking a rare scientific discovery in the region. The new species, named Colobus congoensis, is distinguished by its striking orange-pink facial markings, black face, and dark coat. Until recently, the existence of this primate was known only through a blurry photograph taken in 2008 in the Lomami National Park. Now, after years of research, the species has been formally validated and published in the scientific journal PLOS ONE. The journey to confirm the identity of this mysterious primate began in 2018, when a team led by doctoral student Junior Amboko of Florida Atlantic University launched an expedition into the dense rainforests of central DR Congo. The team sought local knowledge, visiting 52 villages near the suspected habitat of the animal. Only residents in eight of these villages had ever encountered the creature, according to Amboko, who shared his findings with the BBC. His team relied heavily on oral accounts from local communities, which described the monkey’s unique appearance and behavior. One key moment came in November 2018, when researcher Jean-Pierre Kapale captured images of the primate high in the canopy. The photographs revealed distinctive light markings around the mouth and a white stripe beneath the tail, features that set the species apart from others. These observations confirmed that the animal was indeed a new species, prompting further investigation. Over the following four years, researchers collected extensive data on the monkey’s morphology, behavior, vocalizations, and genetic makeup. They also documented how local communities referred to the animal, using names such as “Likweli” and “Kasaba nkoni,” meaning “the one that shakes branches.” Local informants described the monkey’s calls, often heard at dawn, and noted its powerful scent, which some hunters claimed could be detected from a distance. This information helped shape the understanding of the species’ ecological role. Scientists believe the monkeys play a crucial part in seed dispersal within the forest ecosystem, contributing to biodiversity. Their absence could disrupt the delicate balance of their environment. The formal recognition of Colobus congoensis followed months of analysis and peer review. In late 2023, the study was published in PLOS ONE, fulfilling the requirements of the International Code of Zoological Nomenclature. The name Colobus congoensis honors the remarkable biodiversity of DR Congo, while the proposed common name “Likweli” reflects the local cultural significance of the species. The classification places the new species within the broader group of colobines, or leaf-eating monkeys, which lack thumbs due to their specialized diet. This discovery marks the fifth new primate species identified in Africa over the past 75 years, highlighting the ongoing importance of field research in remote regions. Researchers hope that official recognition will lead to increased conservation efforts, particularly given the threat posed by hunting for bushmeat. Local communities, who have long coexisted with the species, may now benefit from legal protections and awareness campaigns aimed at preserving the monkey’s habitat. Despite the progress, much remains unknown about Colobus congoensis. Scientists suggest that other undocumented primate species may still exist in the region, hidden among the dense vegetation. As more studies emerge, the story of this elusive monkey continues to unfold, offering new insights into the rich and complex life of African rainforests.
