Figure 4E , 7A–B

Agama lebretoni Wagner, Barej & Schmitz, 2009: 291 . Type locality: Cameroon, north-east of Mamfe , Mukwecha, Amebisu, N 05°53.866′ E 009°33.495′.

Distribution. It extends from the southeast border of Nigeria to Gabon. In Equatorial Guinea it has been recorded in Bioko ( Drewes et al. 1999) at Basilé ( Bocage 1895 a, 1903), Natividad (Hacienda Natividad) ( Bocage 1895 a, 1903), Punta Frailes ( Boulenger 1906), San Carlos ( Mertens 1941) and Riaba (=Concepción) ( Mertens 1941, 1964), and in Río Muni at Monte Alén National Park ( Lasso et al. 2002), including Monte Mitra Forest, where it specifically has been found in Bisun ( Gonwouo & Nsang 2005) ( Map 3C ).

Comments. Populations from Equatorial Guinea were formerly considered part of Agama agama ( Linnaeus, 1758) until the publication of the comprehensive taxonomic revisions carried out by Wagner et al. (2009a, b) for the genus. Agama lebretoni is recovered as the sister lineage to the clade formed by A. agama , A. paragama Grandison, 1968 , A. picticauda (Peters, 1877) , A. finchi Böhme, Wagner, Malonza, Lötters & Köhler, 2005 , A. parafricana Trape, Mediannikov & Trape, 2012 , and A. africana ( Hallowell, 1844) ( Leaché et al. 2014) . Usually found in disturbed environments, it is uncommon in pristine forests ( Lasso et al. 2002).
