Agama cristata — MEDIANNIKOV, TRAPE & TRAPE 2012: 130 
DistributionGuinea (Conakry), Mali

Type locality: Bomanesco (Sankaran) in Guinea  
Reproductionoviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: MNHN-RA 1901.0394 
DiagnosisDiagnosis: A large species of Agama (total length of adult male up to 340 mm), which is characterized by its bluish-black colouration on the throat and the large nuchal and tail crests of adult males. The species differs from nearly all other Agama species in having a large tail crest, usually reaching the last third of the tail. Only three other species, A. boulengeri, A. kirkii and A. knobeli, have such a prominent tail crest. 
CommentSynonymy: Wermuth (1967) lists this species with a question mark indicating uncertain status. Agama insularis CHABANAUD 1918: 161 has been revalidated from the synonymy of A. cristata by TRAPE 2011.

Nomenclature: Agama cristata is a junior primary homonym of Agama cristata MERREM 1820 (= Corytophanes cristatus (Iguanidae) according to BARABANOV (2008). However, WAGNER & BÖHME (2009) did not accept this suggestion because in accordance to article 23.9.5 of the ICZN (1999) the author failed to refer the case to the Commission of Zoological Nomenclature which would be necessary because both taxa are not congeneric since 1827, where BOIE (in SCHLEGEL1827) connects Merrem’s cristata as type species with his newly described genus Corythophanes.

Distribution: MEDIANNIKOV et al. 2012 give only Mali as distribution. Not in Benin fide ULLENBRUCH et al. 2010.
