I'm aware that the Mwanza rock agama (Agama mwanzae) can be found in the Serengeti National Park, Tanzania but I was also wondering if it occupied this area with any other sympatric species.
The common one should be Agama mwanzae. You'll probably find another four in specific places, maybe around the edges: Acanthocercus atricollis and maybe cyanogaster, Agama agama and A. armata.
Apart from Agama mwanzae you will certainly see Acanthocercus atricollis and if you make a "stop-over" at Olduvai Gorge Acanthocercus cyanogaster with a bit of luck. Agama armata is rather difficult to find as they tend to live on the open plains where you won't be able to search or leave your vehicle (unless you have a permit and a ranger with you for safety). You may be lucky and see one around the kopjes. All three species are sympatric with A. mwanzae but of course there exists a niche differentiation. A. agama is a purely West-African species and does not occur in the Serengeti. Cheers, Wolfgang
True, it looks like, since Spawls et al.'s field guide, A. agama has been split into numerous species, and Leache et al.'s phylogeny suggests they are not even closely related to A. agama proper. Would it be lionotus that comes closest to Serengeti?
But you will not find Acanthocercus cyanogaster, that species is restricted to the Horn of Africa, mainly Ethiopia. Older records from this taxon In Kenya and more southards are misinterpretations and correctly refer A. atricollis.
