Based on these collections, literature, molecular analysis of selected specimens, and examination of Linnean type-specimens of A. agama, we review the phylogeny, taxonomy, geographic distribution and ecology of the West African species of the genus Agama. Seventeen different species are recognized in the genus Agama in West Africa, northern Cameroon and Chad: A. africana, A. agama, A. boensis, A. boueti, A. boulengeri, A. castroviejoi, A. cristata, A. doriae benueensis, A. gracilimembris, A. insularis, A. lebretoni, A. paragama, A. sankaranica, A. weidholzi, and three new species. We design a lectotype for A. agama (Linnaeus, 1758) and attribute to A. wagneri, sp. nov., the populations from northern and central Cameroon of the A. agama complex. Agama parafricana, sp. nov., is described from wet savanna areas of Togo and Benin. Agama sylvanus from southern Ghana is a junior synonym of A. africana. Agama cf. impalearis from northern Niger and Mali corresponds to an nondescribed species. Agama boensis is resurrected from the synonymy of A. sankaranica. According to biogeographic areas, four species are Sahelian, seven species are Sudanian, four species are Guinean, and two species are ubiquitous. specialized REPTILE TAXONOMIE PHYLOGENIE BIOLOGIE MOLECULAIRE GENRE AFRIQUE DE L'OUEST CAMEROUN TCHAD TOGO BENIN GHANA NIGER MALI SOUDAN GUINEE 080ZOOGEN02 19 2 115-142 2012 1026-2296 https://www.documentation.ird.fr/hor/fdi:010069121 1026-2296 [F B010069121] https://www.documentation.ird.fr/hor/fdi:010069121 https://www.documentation.ird.fr/intranet/publi/depot/2017-02-08/010069121.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-02-08 2025-05-20 fdi:010069121 fre
