The Zoochat Photographic Guide to Old World Primates

CERCOPITHECIDAE continued
Old World Monkeys

About 155 species in two subfamilies, Colobinae (c.10-20 species of colobus in Africa, and c.50-60 species of langurs in Asia) and Cercopithecinae (c.60 species of baboons and guenons in Africa, and c.20-25 species of macaques in Asia).

.....................................................................................

Subfamily CERCOPITHECINAE
About 80 species in 12 genera. There are 67 species represented in the Zoochat galleries.

Most species are African - guenons, mangabeys, baboons, etc - with only about 20-25 species being from Asia (the macaques, all of which are in a single genus Macaca).

The subfamily is divided into two tribes as presented below. The genera are split about as far as they will go so it is unlikely any more will be created in the future. There have been many fewer genera in the past however. Until the 1970s to 1980s, for example, all the Cercopithecini species were usually placed in a single genus (Cercopithecus) instead of the five recognised today. At its most consolidated the subfamily was comprised of only four genera - Cercopithecus for guenons, Macaca for macaques, Cercocebus for mangabeys, and Papio for baboons (including Mandrill, Drill, and Gelada).


Tribe: Cercopithecini

Allenopithecus (Allen's Swamp Monkey) - one species, depicted.
Miopithecus (Talapoins) - two species, both depicted here.
Erythrocebus (Patas Monkey) - one or two species, both depicted here.
Chlorocebus (Vervets or Green Monkeys) - six species, all of which are depicted here.
Cercopithecus (Guenons) - about twenty-six species, nineteen of which are depicted here.

Tribe: Papionini

Macaca (Macaques) - about twenty-three species, twenty-one of which are depicted here.
Cercocebus (White-eyelid Mangabeys) - six species, all of which are depicted here.
Mandrillus (Mandrill and Drill) - two species, both depicted here.
Lophocebus (Crested Mangabeys) - six species, only two of which are depicted here.
Rungwecebus (Kipunji) - one species, not depicted here.
Papio (Baboons) - five species, all of which are depicted here.
Theropithecus (Gelada) - one species, depicted.

 

Allenopithecus
One species.

Until the 1970s this genus was included within Cercopithecus.



Allen's Swamp Monkey Allenopithecus nigroviridis
Monotypic.


Found in the western Congo Basin, in the Congo Republic and the western DRC.

Miopithecus
Two species, both of which are represented in the Zoochat galleries.

Until the 1980s this genus was included within Cercopithecus. Formerly only one species was recognised, but this was eventually split in two with the description of the Northern Talapoin M. ogouensis in 1997.



Northern or Gabon Talapoin Miopithecus ogouensis
Monotypic.


Found in west Africa from Cameroon, Equatorial Guinea and Gabon to the western parts of the Congo Republic and DRC.

Erythrocebus
One or two species.

Until the 1970s this genus was included within Cercopithecus.



Patas Monkey Erythrocebus patas
Three subspecies are most often used: baumstarki, patas and pyrrhonotus. There is no real consensus on this however, and there are a number of further subspecies which have been named. Conversely, in Colin Groves' 2001 book Primate Taxonomy the species was treated as being monotypic.


Found across central Africa, from the west coast (Mauritania to Guinea) right through to Kenya and Tanzania: baumstarki has a very limited distribution in northern Tanzania (and formerly southern Kenya); while patas (in the west) and pyrrhonotus (in the east) cover the rest of the range. Has also been introduced to Puerto Rico.

Blue Nile Patas Monkey Erythrocebus poliophaeus
Monotypic

Traditionally there has only been one species of Patas Monkey, although the number of recognised subspecies has varied considerably. In 2017 one of the former subspecies was split as a full species, and named the Blue Nile Patas Monkey Erythrocebus poliophaeus. The paper describing this "species" is rather unconvincing, being based solely on appearance. The authors also recommend splitting the subspecies baumstarki as a full species. The paper can be read here: http://static1.1.sqspcdn.com/static/f/1200343/27795196/1515432572007/PC31_Gippoliti_Patas_Ethiopia.pdf?token=cIj1jDNWn0VX8tn2QOizgCoV2W8=


Found along the Blue Nile River valley, in northwest Ethiopia and eastern Sudan.

The photo below by @YuanChang at the Nanchang Zoo, China, is also poliophaeus - several Chinese zoos keep this taxa but they may not be a pure population.

Chlorocebus
Six species, all of which are represented in the Zoochat galleries.


Formerly this genus was included within Cercopithecus - it was first split as a distinct genus in 1989, but this was not universally accepted until the 2000s. The taxonomy has varied considerably over the decades, from there being just a single species (C. aethiops) through to the currently-accepted situation of six species.



Grivet Chlorocebus aethiops
Monotypic.


Found in northeast Africa, in Sudan east of the White Nile, in Eritrea, and in Ethiopia east to the Rift Valley.

Malbrouck Monkey Chlorocebus cynosuros
Monotypic.


Found in the southwest Congo Basin, in the southern DRC, Angola and Zambia, and into the northern edge of Namibia.


Photo by @alexkant at Gradina Zoologica Bucuresti (Bucharest Zoo), Romania (this may not be a pure animal - cynosuros is the only member of the genus with a face which isn't black - and on Zootierliste this zoo is listed as holding non-subspecific animals, but it looks good enough as a representation of the species).

Bale Mountains Vervet Chlorocebus djamdjamensis
Monotypic.


Endemic to the Bale Mountains of Ethiopia.

Vervet Monkey Chlorocebus pygerythrus
Five subspecies: excubitor, hilgerti, nesiotes, pygerythrus, rufoviridis. Lots of other subspecies formerly recognised are now considered invalid. The subspecies excubitor and nesiotes are insular races which are not represented in the Zoochat galleries.


Found down the eastern side of Africa from Ethiopia to South Africa: excubitor in the Wittu Islands of the Lamu Archipelago off Kenya; hilgerti in the northeast part of the range from Ethiopia to Uganda, Kenya and northern Tanzania; nesiotes restricted to Pemba and Mafia Islands in the Zanzibar Archipelago off Tanzania; pygerythrus in southern Africa (South Africa, Botswana, and southern Zimbabwe and Mozambique); and rufoviridis from central-eastern Africa (between hilgerti and pygerythrus).

Tantalus Monkey Chlorocebus tantalus
Three subspecies: budgetti, marrensis, tantalus. Other subspecies formerly recognised are now considered invalid.

Cercopithecus
About twenty-six species, nineteen of which are represented in the Zoochat galleries.


This genus also formerly included all the genera above (Allenopithecus, Miopithecus, Erythrocebus and Chlorocebus). The "lhoesti group" of guenons (containing three species) may also be split into a separate genus, Allochrocebus, although here I have retained them in Cercopithecus.


The names "guenon" and "monkey" can be used interchangeably for all Cercopithecus species depending on personal preference.



Because there are so many species, many with multiple subspecies, and with most of the species having photographs available in the Zoochat galleries (19 out of 26 species), I have divided the genus over several posts corresponding to their taxonomic divisions.


Post one: the lhoesti group (three species - lhoesti, preussi, solatus - which may be separated into their own genus, Allochrocebus).

Post two: the hamlyni group (two species - hamlyni, lomamiensis).

Post three: the neglectus group (one species, neglectus).

Post four: the diana group (three species - diana, dryas, roloway).

Post five: the mitis group (three to five species - albogularis, dogetti, kandti, mitis, nictitans).

Post six: the mona group (six species - campbelli, denti, lowei, mona, pogonias, wolfi).

Post seven: the cephus group (six species - ascanius, cephus, erythrogaster, erythrotis, petaurista, sclateri).

 

Cercopithecus - "lhoesti group"
Three species.


The three species in this grouping were recently moved to a separate genus Allochrocebus, as molecular studies seem to show that they are more closely related to vervets (Chlorocebus) than to Cercopithecus guenons. This however doesn't seem to be widely followed, so I have left them in Cercopithecus.



L'Hoest's Monkey Cercopithecus lhoesti
Monotypic. Formerly included Cercopithecus preussi as a subspecies.


Found in the northeastern Congo Basin: in northeast DRC, Rwanda and Burundi, and western Uganda.


Photo by @Himimomi at Nanning Zoo, China.


L'Hoest's monkey | ZooChat


Preuss' Monkey Cercopithecus preussi
Two subspecies: insularis and preussi.

Formerly treated as subspecies of L'Hoest's Monkey C. lhoesti.


Found in west Africa: on Bioko Island off Cameroon (insularis), and in western Cameroon and eastern Nigeria (preussi).


There are no photos representing this species in the Zoochat galleries.


Sun-tailed Guenon Cercopithecus solatus
Monotypic.


Endemic to Gabon. Only discovered in 1984 and described in 1988.


There are no photos representing this species in the Zoochat galleries.

 

Cercopithecus - "hamlyni group"
Two species.



Owl-faced or Hamlyn's Monkey Cercopithecus hamlyni
Two subspecies have been named (hamlyni and kahuziensis) but the latter is likely not valid. IUCN treats the species as monotypic pending further studies.


Found in northeast DRC and western Rwanda. The subspecies kahuziensis is supposed to be restricted to Mt Kahuzi in the DRC and is characterised mainly by the absence of a white nose-stripe, but this is apparently variable even within individual populations.

Lesula Cercopithecus lomamiensis
Monotypic.


Endemic to the Lomami Basin of the central DRC. Only discovered in 2007 (as a genuine discovery, not a split from a known species), and described in 2012.


There are no photos representing this species in the Zoochat galleries.

 

Cercopithecus - "neglectus group"
One species.



De Brazza's Monkey Cercopithecus neglectus
Monotypic.


Found across central Africa from Nigeria, Cameroon and Angola in the west, to western Uganda in the east, as well as in western Kenya and southwest Ethiopia.

Cercopithecus - "diana group"
Three species.

Originally this group only included one species, the Diana Monkey Cercopithecus diana, with the other two species being treated as subspecies. According to some studies, the Dryas Monkey C. dryas should actually be placed in the genus Chlorocebus (vervets) and isn't closely related to the Diana Monkey at all.



Diana Monkey Cercopithecus diana
Monotypic.


Found in west Africa, from Sierra Leone to Ivory Coast.

Diana monkey | ZooChat


Dryas Monkey or Salonga Guenon Cercopithecus dryas
Monotypic.

Formerly treated as a subspecies of Diana Monkey C. diana, from which it is geographically isolated. The Zaire Diana Monkey or Salonga Guenon C. salongo, described in 1977 (description of that form here: Further information on the new monkey species, Cercopithecus salongo Thys van den Audenaerde, 1977), is now considered to be the same species - IUCN says it is an "age-variant" of C. dryas - although not all authorities agree. Some taxonomists now place this species in the genus Chlorocebus with the vervet monkeys.


Found only in central DRC.


There are no photos of this species in the Zoochat galleries.


Roloway Monkey Cercopithecus roloway
Monotypic.


Found only in Ivory Coast and Ghana, just east of the range of C. diana.

Cercopithecus - "mitis group"
Three to five (or more) species.



Sykes's Monkey, Samango Monkey, or White-throated Guenon Cercopithecus albogularis
Twelve (or more) subspecies: albogularis, albotorquatus, erythrarchus, francescae, kibonotensis, kolbi, labiatus, moloneyi, monoides, phylax, schwarzi, zammaranoi.

Formerly considered to be a subspecies of the Blue Monkey Cercopithecus mitis, a treatment which is still followed by many authorities.

Note that another species of guenon, Cercopithecus erythrogaster, is also called the White-throated Guenon.


Found throughout east to southern Africa: albogularis in southeast Kenya and northeast Tanzania, including Zanzibar Island (if this taxa is restricted to Zanzibar then the mainland form is called kibonotensis); albotorquatus in north Kenya and south Somalia; erythrarchus in southeast Africa (Malawi, Zimbabwe, Mozambique, northeastern South Africa); francescae in Malawi; kibonotensis in southeast Kenya and northeast Tanzania (if albogularis is restricted to Zanzibar Island; otherwise kibonotensis is a synonym); kolbi in the central highlands of Kenya; labiatus in southeastern South Africa; moloneyi from the Udzungwa Mountains in Tanzania into Zambia and Mozambique; monoides on the coastal plain of central and south Tanzania into northeast Mozambique; phylax from the Lamu Archipelago off Kenya; schwarzi in northeastern South Africa; and zammaranoi in Somalia.


Photo by @alexkant at Ben Shemen Forest Monkey Park, Israel (on Zootierliste this is listed as being the subspecies albogularis but there is a huge amount of dispute about the limits of mitis/albogularis subspecies [note that the Zoochat photo is labelled as "Blue monkey / Cercopithecus mitis"]).

Blue Monkey Cercopithecus mitis
About seven (or more) subspecies: botourlinii, heymansi, manyaraensis, mitis, opisthosticus, schoutedeni, stuhlmanni. Other subspecies have been used/discarded over time, and others have been split or are potential splits into separate species (see below).

The Silver Monkey C. doggetti and Golden Monkey C. kandti may be treated either as subspecies of C. mitis or split as full species (I have split them for the purposes of this thread). Syke's Monkey C. albogularis is now most commonly separated from C. mitis, and I have followed that here. There is considerable confusion around mitis and albogularis, with not much in the way of agreement about the limits of the many named subspecies. The IUCN Red List includes all of the above in Cercopithecus mitis and gives it seventeen subspecies.


Found over most of central to east Africa, and north to Ethiopia: botourlinii in western Ethiopia; heymansi in the Lomami Basin of the DRC; manyaraensis from Manyara in Kenya; mitis in western Angola; opisthosticus in the southeast Congo Basin (DRC and Zambia, extending into Angola and Tanzania); schoutedeni in eastern DRC; and stuhlmanni in the northeast DRC east to southwest Kenya, Uganda and southeast South Sudan.

Greater Spot-nosed Monkey or Putty-nosed Guenon Cercopithecus nictitans
Five subspecies: insolitus, ludio, martini, nictitans, stampflii. The IUCN recognises just two subspecies, treating insolitus, ludio and stampflii as synonyms of martini.


Found in two separate areas, in west Africa (Liberia and Ivory Coast), and west-central Africa (Nigeria to western DRC): insolitus in Nigeria; ludio in southeast Nigeria and southwest Cameroon; martini on Bioko Island off Cameroon; nictitans in west-central Africa (east of ludio range); and stampflii in Liberia and Ivory Coast.

Dent's Monkey Cercopithecus denti
Monotypic.

Formerly treated as a subspecies of Wolf's Monkey C. wolfi or the Crowned Monkey C. pogonias or the Mona Monkey C. mona, depending at which stage of taxonomic splitting it was.


Found in the Congo Basin: in the Congo Republic, CAR, DRC, Rwanda, and western Uganda.


There are no photos of this species in the Zoochat galleries - photos taken in Dubai (United Arab Emirates) and labeled as being Dent's Monkeys are actually Mona Monkeys C. mona.


Lowe's Monkey Cercopithecus lowei
Monotypic.

Formerly treated as a subspecies of Campbell's Monkey C. campbelli, and before that of the Mona Monkey C. mona.


Found in west Africa, from Ghana and Ivory Coast.

Crowned or Golden-bellied Monkey Cercopithecus pogonias
Three subspecies: grayi, nigripes, pogonias. A fourth subspecies, schwarzianus, known from one specimen from Mayumbe, DRC, is sometimes recognised but otherwise synonymised with C. p. grayi.

Formerly treated as a subspecies of Mona Monkey C. mona. Wolf's Monkey C. wolfi and Dent's Monkey C. denti have also previously been treated as subspecies of C. pogonias.


Found in central Africa from Cameroon to Angola in the west, and across the Congo Basin to the eastern DRC: grayi from Cameroon across the DRC; nigripes from Gabon and the southwestern Congo Republic; and pogonias from Bioko Island and the adjacent mainland of southeast Nigeria and Cameroon.

Cercopithecus - "cephus group"
Six species.



Red-tailed Guenon Cercopithecus ascanius
Five subspecies: ascanius, atrinasus, katangae, schmidti, whitesidei.


Found in central Africa: ascanius in northern Angola and southwest DRC; atrinasus only on the Lunda Plateau in northeast Angola; katangae i southern and central DRC, just edging into northeastern Angola and northwestern Zambia; schmidti in northeast DRC into Uganda and western Kenya and Tanzania; and whitesidei in central DRC.

There are no photos of this species in the Zoochat galleries.

 

I never found that photo. I've added it into the thread now.

(The photo only shows in the search results for me if the search-term is specifically "Dent's mona", and not for "Dent's monkey", "Dent's guenon", or "Cercopithecus denti").

 

However, it *is* the only result if you search for the single word "Dent"
