The lesula (Cercopithecus lomamiensis) is a species of Old World monkey in the guenon family, found in the Lomami Basin of the Congo. Though known to locals, it was unknown to the international scientific community until it was discovered in 2007 and confirmed in a 2012 publication. The lesula is the second new species of African monkey to be discovered since 1984. [1] This monkey is described to have human looking eyes and a blue bottom [2] [3] “And adult males have a huge bare patch of skin in the buttocks, testicles and perianal area,” said John A. Hart, the researcher who described the monkey. “It’s a brilliant blue, really pretty spectacular.” [4]


The species was listed among the Top 10 New Species 2013 discovered in 2012 as selected by the International Institute for Species Exploration at Arizona State University out of more than 140 nominated species. Its distinctiveness is its human-like eyes, genital area and booming dawn chorus. The selection was declared on 22 May 2013. [5] [6]


Lesula booms

The lesula lives in rainforests in the Democratic Republic of Congo, with the 2007 specimen found in captivity in the village of Opala. Since that sighting, it has also been seen in the wild. Its range is between the Lomami and Tshuapa rivers in the central part of the country. [7]


The lesula is vulnerable to hunting for bushmeat. [8] Protecting the species could be challenging, as species with such a small range can go from vulnerable to seriously endangered in a few years. The lesula's range is within the Tshuapa–Lomami–Lualaba Conservation Landscape, and the Lomami National Park has been proposed to protect this and other species in the region. The Lesula also live in the Ngorongoro Crater conservation area of Tanzania. [7]


The Lesula are generally described by researchers as quiet and shy. [9] They also tend to usually live in small family groups of around five members or less. The Lesula's days consist of leisurely activities such as foraging for fruits and vegetation, grooming, and resting.

The dawn chorus occurs when birds sing at the start of a new day. In temperate countries this is most noticeable in spring when the birds are either defending a breeding territory, trying to attract a mate, or calling in the flock. In a given location, it is common for different species to do their dawn singing at different times. In a study of the Ecuadorian forest, it was determined that birds perching higher in the trees and birds with larger eyes tend to pipe up first. These correlations may be caused by the fact that both would also correlate with the amount of light perceived by the bird.

Old World monkey Family of mammals

Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae. Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons, macaques, and mabahlls. Common names for other Old World monkeys include the talapoin, guenon, colobus, douc, vervet, gelada, mangabey, langur, mandrill, surili (Presbytis), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 55 million years ago.

Blue monkey Species of Old World monkey

The blue monkey or diademed monkey is a species of Old World monkey native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia. It sometimes includes Sykes', silver, and golden monkeys as subspecies.

Dryas monkey Species of Old World monkey

The Dryas monkey, also known as Salonga monkey, ekele, or inoko, is a little-known species of guenon found only in the Congo Basin, restricted to the left bank of the Congo River. It is now established that the animals that had been classified as Cercopithecus salongo were in fact Dryas monkeys. Some older sources treat the Dryas monkey as a subspecies of the Diana monkey and classify it as C. diana dryas, but it is geographically isolated from any known Diana monkey population.

Virunga National Park

Virunga National Park is a national park in the Albertine Rift Valley in the eastern part of the Democratic Republic of the Congo. It was created in 1925 and is among the first protected areas in Africa. In elevation, it ranges from 680 m (2,230 ft) in the Semliki River valley to 5,109 m (16,762 ft) in the Rwenzori Mountains. From north to south it extends about 300 km (190 mi), largely along the international borders with Uganda and Rwanda in the east. It covers an area of 8,090 km2 (3,120 sq mi) and is listed in the List of World Heritage in Danger since 1994.

Kipunji Species of Old World monkey

The kipunji, also known as the highland mangabey, is a species of Old World monkey that lives in the highland forests of Tanzania. The kipunji has a unique call, described as a 'honk-bark', which distinguishes it from its relatives, the grey-cheeked mangabey and the black crested mangabey, whose calls are described as 'whoop-gobbles'.

De Brazzas monkey Species of Old World monkey

De Brazza's monkey is an Old World monkey endemic to the riverine and swamp forests of central Africa. The largest species in the guenon family, it is one of the most widespread arboreal African primates. Aside from size, it can be differentiated from other cercopithecus monkeys by its orange diadem and white beard. Due to its cryptic nature, the species is not well documented in all of its habitats but has shown unique traits such as pair-bonding and aggressive behavior towards other guenons.

Wildlife of Cameroon

The wildlife of Cameroon is composed of its flora and fauna. Bordering Nigeria, it is considered one of the wettest parts of Africa and records Africa's second highest concentration of biodiversity. To preserve its wildlife, Cameroon has more than 20 protected reserves comprising national parks, zoos, forest reserves and sanctuaries. The protected areas were first created in the northern region under the colonial administration in 1932; the first two reserves established were Mozogo Gokoro Reserve and the Bénoué Reserve, which was followed by the Waza Reserve on 24 March 1934. The coverage of reserves was initially about 4 percent of the country's area, rising to 12 percent; the administration proposes to cover 30 percent of the land area.

Campbells mona monkey Species of Old World monkey

Campbell's mona monkey, also known as Campbell's guenon and Campbell's monkey is a species of primate in the family Cercopithecidae found in the Ivory Coast, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Senegal, and Sierra Leone. It was named for Henry Dundas Campbell, in 1838. Lowe's mona monkey was previously considered a subspecies of Campbell's mona monkey. The International Union for Conservation of Nature has rated this species as being a near-threatened species because it has a wide range and is able to adapt to degraded habitats.

Thollons red colobus Species of Old World monkey

Thollon's red colobus, also known as the Tshuapa red colobus, is a species of red colobus monkey from the Democratic Republic of the Congo and lower Republic of the Congo. It is found south of Congo River and west of Lomami River. It had once been considered a subspecies of the P. badius. It was recognised as a distinct species by Dandelot in 1974, and this was followed by Groves in 2001, while others have suggested it should be considered a subspecies of P. rufomitratus.
