When the 18th century French naturalist Goerge-Louis Leclerc, Comte de Buffon obtained the first specimens of these monkeys, they were mistakenly labelled as having come from Mangabe in Madagascar, there are of course no monkeys in Madagascar, but he wasn't aware of this and assumed that they really had come from Mangabe and decided to call them mangabeys, until they could establish what the native name for them was, the name stuck. It was originally assumed that all of the various species were closely related and are thus all called mangabeys, but in fact recent genetic evidence, has shown that there are two distinct groups, baboon-mangabeys more closely related to baboons and geladas and drill-mangabeys more closely related to drills and mandrills. Originally there were thought to be just two species of baboon mangabeys the black and the grey-cheeked, however recently the late Australian scientist Colin Groves, a bit of a specialist on primate taxonomy, split the black in to two species and the grey-cheeked in to four species.  

 

Baboon-mangabeys/crested mangabeys

 

Black mangabey (Lophocebus aterrimus)

Opdenbosch’s mangabey (Lophocebus opdenboschi)

 

Grey-cheeked mangabey (Lophocebus albigena)

Uganda mangabey (Lophocebus ugandae)

Osman Hill’s or rusty mantled mangabey (Lophocebus osmani)

Johnston’s mangabey (Lophocebus johnstoni)

 

Drill-mangabeys/white-eyelid mangabeys

 

Sooty mangabey (Cercocebus atys)

White-naped mangabey (Cercocebus lunulatus)

Red-capped mangabey (Cercocebus torquatus)

Golden-bellied mangabey (Cercocebus chrysogaster)

Agile mangabey (Cercocebus agilis)

Tana River mangabey (Cercocebus galeritus)

Sanje mangabey (Cercocebus sanje)

 

Kipunji

 

Rungwecebus kipunji

 

In Tanzania in 2003 a team of scientists led by Tim Davenport in the forests of Mt Rungwe in the Southern Highlands, discovered what they initially believed was a new species of mangabey, completely independently in 2004, Trevor Jones and Richard Laizzer observed what proved to be the same new species of monkey in the Ndundulu Forest in the Udzungwa Mountains. Knowing that these new monkeys must be very rare, they chose to name it without first obtaining a specimen, in 2005 they called it the highland mangabey and gave it the scientific name Lophocebus kipunji thinking it was a relative of the grey-cheeked mangabeys.  Later a local hunter on Mt Rungwe killed a monkey, this was obtained as the first specimen, genetic analysis showed that it was not in fact really a mangabey at all, but was even more closely related to the Papio baboons, in 2006 it was then placed in its own entirely new genus Rungwecebus, meaning Mt Rungwe monkey, the species name kipunji is the local name for these monkeys in the Rungwe area.

 

To see a Kipunji in the wild and certainly to get any photos would be a challenge and require a lot of luck, just seeing one, even if it’s only a glimpse is not impossible, your best chance would be to visit the Livingstone Forest in Kitulo National Park in the Southern Highlands. The population in the Ndundulu Forest is very small, this forest is high up on the western side of the Udzungwa Mts in the Kilombero Forest Reserve outside the national park, (why it still hasn’t been made part of UMNP, I don’t know). Not many tourists go into the Ndundulu Forest, except perhaps for birders looking for the Udzungwa partridge, this bird was first discovered by a group of Danish ornithologists in 1991, the Danish scientists had been camped in Ndundulu for months studying the birds. During this time they in fact briefly glimpsed kipunjis on three occasions, however, they assumed that what they had seen were just Sanje mangabeys, they had no idea that they had actually spotted a then entirely unknown monkey. It was however their report on their time in the forest, that led Trevor Jones to visit Ndundulu, to look for new populations of Sanje mangabeys, and this led to his discovery of the kipunjis there. The fact that the Danes only caught brief glimpses of the monkeys, despite being there for a long time clearly indicates how hard they are to see there. In Udzungwa National Park Sanje mangabeys have been habituated, so that tourists as well as scientists can observe them, perhaps in time a troop of kipunjis will be habituated in the Livingstone Forest in Kitulo NP, allowing tourists to be reasonably certain of seeing and even photographing them. Kitulo NP which is actually known mostly for its montane grassland and wildflowers can be reached very easily from Mbeya, although it’s a fairly long way, you can also get there from Iringa, so you could go from Mikumi, or UMNP or Ruaha down to Kitulo by road.

 

If you have any photos or videos of any of the mangabey species or of the kipunji please add them to this thread.

The grey-cheeked or western grey-cheeked mangabey (Lophocebus alibgena) occurs from the west coast of Central Africa east to the Congo River, it's probably most easily seen in Gabon, can also be seen in southern Cameroon, Congo Rep. and southwestern CAR. I had a rather distant view of these monkeys from the WCS Langoue Research Camp in Ivindo National Park and another rather distant from the viewing platform at Langoue Bai, to give an idea of how far away they were, the following photo was taken with my Canon EOS 20D and a 500mm lens with a 1.4X converter attached.

Besides the two obvious monkeys in the middle, there's another right over on the left and one near the top right corner

The IUCN redlist does not as yet recognise these splits, so they still regard the grey-cheeked mangabey as a single species, thus they don't have range maps for each of these newly recognised species. The following map therefore shows the range of the grey-cheeked mangabey as a single species, the distribution maps in Mammals of Africa and the Kingdon Field Guide do show the different species, although he hasn't illustrated the different species, so there is still just one illustration.

It is stated on one or two websites that the Uganda mangabey (Lophocebus ugandae) is Uganda’s only endemic monkey, but it’s not in actual fact endemic to Uganda, in the south of Uganda an isolated population occurs in a small area of forest close to the eastern shore of Lake Victoria and this forest extends over the border into Northwestern Tanzania, where it is protected in the Minziro Forest Reserve, so the mangabeys also occur in Tanzania but only in Minziro FR. The main population occurs further north in suitable forest habitat from the northeastern shore of Lake Victoria west to the eastern side of the Albertine Rift (the western branch of the Rift Valley).

 

The following science paper by Colin Groves on these mangabeys, was clearly published before the discovery that there are Uganda mangabeys in Minziro FR in Tanzania, it includes illustrations of the four species. 

 

The Endemic Uganda Mangabey, Lophocebus ugandae, and Other Members of the Albigena-Group (Lophocebus)

 

The best place to see the Uganda mangabey, I would think is Kibale Forest and Bigodi Swamp, although I didn’t see any on my last visit to Bigodi, but I did when I first went there.

The Johnston’s mangabey (Lophocebus johnstoni) occurs from the western side of the Albertine Rift throughout most of eastern DRC and across northern DRC to the Congo River, it also occurs in the west of Rwanda and Burundi and in Semuliki NP in Uganda, which is the easternmost extension of the great Ituri Rainforest in the DRC.

When I visited Uganda, I should have been aware that of the fact that the grey-cheeked mangabey had been split into four species, but I wasn't, so when I posted the first of these two photos and the three in the previous post in my trip report Where the Rainforest Meets the Savannah: Uganda February 2018 , I just labelled them grey-cheeked mangabeys. 

 

The final species which I’ve not seen, Osman Hill’s or the rusty-mantled mangabey (Lophocebus osmani) only occurs in a very small isolated area on the Nigeria/Cameroon border.

The red-capped mangabey (Cercocebus torquatus) sometimes called the collared mangabey is endemic to the west coast of Central Africa and Nigeria, from the vicinity of Lagos in the northwest south down the coast to Gabon and over the border into Conkouati-Douli NP in the Congo Republic. Its current distribution is much patchier than that shown on the map, since these monkeys are now only common in areas where hunting pressure is low.

Loango National Park in Gabon is certainly one of the best places to look for this mangabey, Tsam-Tsam Ecolodge near Lambarene would I believe be another good place to see them, but I’ve not been there.
