Bibliography of the genus Acanthocercus
Biodiversity of the family Agamidae








Genus
Acanthocercus

Ridgeback Agamas

Keilrückenagamen

Kølrygagamer

1843 Acanthocercus Fitzinger (type species: Stellio erythrogaster Nikolski 1896)
Contents: 13 species, none of which are endemic.
Remarks: Previously regarded as a synonym of Agama (e.g., Wermuth 1967). Although the revalidation of Acanthocercus was suggested by Baig & Böhme (1991), the formal resurrection was made by Schätti & Gasparetti (1994) and confirmed by Baig & Böhme (1997).
Distribution: Angola, Botswana, Burundi, Congo-Kinshasa, Djibouti, Eritrea, Eswatini, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Oman, Rwanda, Saudi Arabia, Somalia, South Africa (Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, North West Province), Tanzania, Uganda, Yemen, Zambia, Zimbabwe.

Acanthocercus atricollis

Black-necked Ridgeback Agama, Black-necked Arboreal Agama, Black-necked Tree Agama, Black-necked Agama, Southern Tree Agama, South African Agama

Blaukehlagame

1849 Agama atricollis Smith
Stellio atricolis [sic] Bocage 1896
Agama cyanogaster atricollis Klausewitz 1953
Acanthocercus atricollis Baig & Böhme 1997
1851 Stellio capensis Dumeril in Dumeril & Dumeril (Wagner, Greenbaum, Bauer, Kusamba & Leaché 2018)
1866 Stellio nigricollis Bocage (Wagner, Greenbaum, Bauer, Kusamba & Leaché 2018)

Remarks: Previously included cyanocephalus, gregorii, kiwuensis, minutus, and ugandaensis. Taxonomic history has been turbulent. Many authors have confused atricollis and cyanogaster. Boulenger (1896) regarded them as perhaps inseparable, and some authors have synonymised the two (e.g., Parker 1942; Loveridge 1957). Klausewitz (1957) regarded them as distinct, an also Largen & Spawls (2006) and Wagner & Böhme (2007) regarded them as separate (although somewhat poorly differentiated) species. Records of atricollis-like specimens from SE. Congo-Kinshasa (Klausewitz 1957; Wagner, Greenbaum, Bauer, Kusamba & Leaché 2018) are provisionally included herein as atricollis.
Distribution: Botswana, Congo-Kinshasa, Eswatini, Malawi, Mozambique, South Africa (Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, North West Province), Zimbabwe.


Acanthocercus branchi

Zambian Ridgeback Agama

Sambianische Keilrückenagame

Zambiansk Kølrygagam

2012 Acanthocercus branchi Wagner, Greenbaum & Bauer

Distribution: Congo-Kinshasa, Malawi, Zambia.


Acanthocercus cyanocephalus

Blue-headed Ridgeback Agama, Angolan Tree Agama

Blaukopfagame

Blåhovedet Kølrygagam

1925 Agama cyanocephala Falk
Acanthocercus cyanocephalus Ceríaco, Bauer, Blackburn & Lavres 2014

Remarks: Previously regarded as a synonym of atricollis (e.g., Wermuth 1967). Revalidated as a separate species by Ceríaco, Bauer, Blackburn & Lavres (2014), who referred to the at that time unpublished revisionary work by Wagner, Greenbaum, Bauer, Kusamba & Leaché (2018).
Distribution: Angola, Congo-Kinshasa, Namibia, Zambia.


Acanthocercus cyanogaster

Blue-bellied Ridgeback Agama, Blue-throated Agama, (Blue-headed Tree Agama)

Blaubäuchige Keilrückenagame

Blåbuget Kølrygagam

1835 Stellio cyanogaster Rüppell
Agama cyanogaster Blanford 1870
Acanthocercus cyanogaster Baig & Böhme 1997

Remarks: Previously confused with atricollis (see remarks under that species). According to Largen & Spawls (2006), cyanogaster is currently known with certainty only from Ethiopia and Eritrea. Following these authors, all records of cyanogaster from other than these two countries are regarded herein as representing various species of the atricollis complex. However, the distribution of the many species of this group is unclear (Wagner, Greenbaum, Bauer, Kusamba & Leaché 2018). Previously included adramitana, annectens, phillipsi, and yemenensis (e.g., Wermuth 1967). The type locality is Jeddah (Saudi Arabia), but should be Massawa (Ethiopia) (Anderson 1896).
Distribution: Eritrea, Ethiopia.
