Checklist of Endemic Vertebrate Genera
This list of vertebrate genera found exclusively in Guyana is based on the taxonomy used in Wilson & Reeder (2005) for mammals, Dickinson (2003) for birds, the EMBL Reptile Database (2005) for reptiles, Frost (2004) for amphibians, and FishBase 2004 (2004) for fishes. For further details on the sources and possible inaccuracies in the list see Sources & Caveats.
OC = a FishBase occurrence record suggests a specimen from another country outside normal stated range (these vary widely in reliability from obvious misidentifications to being almost certainly correct)
Acanthocharax 1 spp. (Freshwater Fish Characidae)
Aphyodite OC 1 spp. (Freshwater Fish Characidae)
Mazarunia 1 spp. (Freshwater Fish Cichlidae)
Skiotocharax 1 spp. (Freshwater Fish Crenuchidae)
