Phelsuma madagascariensis is a species of day gecko that lives in Madagascar. It is among the most widespread day geckos and is found in a wide range of habitats.Glaw, F. and Vences, M. (2007). A Field Guide to the Amphibians and Reptiles of Madagascar. 3rd edition. With a length of up to , it is also the largest day gecko in Madagascar. (The highly restricted Round Island day gecko is the only other extant species with a similar maximum length; the extinct Rodrigues giant day gecko was even larger.)
Subspecies There are several subspecies:
Phelsuma madagascariensis madagascariensis (Madagascar day gecko) Phelsuma madagascariensis kochi (Koch's giant day gecko) Phelsuma madagascariensis boehmei (Boehme's giant day gecko)
Phelsuma grandis, the Madagascar giant day gecko, was previously considered a subspecies of Phelsuma madagascariensis but has now been elevated to a full species.Raxworthy, C.J.; C.M. Ingram; N. Rabibisoa and R.G. Pearson (2007) Applications of Ecological Niche Modeling for Species Delimitation: A Review and Empirical Evaluation Using Day Geckos (Phelsuma) from Madagascar.
