[4] Furcifer willsii is endemic to east-central and northeastern Madagascar, along with an isolated range in the north-central part of the island.

[6] Records show that this species has been found Tsingy de Bemaraha Strict Nature Reserve.

F. willsii may have been sighted once in western Madagascar at Ankarafantsika National Park, although this observation has not been verified as of 2007.

Reports from Tsingy de Bemaraha Strict Nature Reserve are uncertain: they may be of F. willsii, F. petteri, or a similar, undescribed species.

[1] Furcifer willsii is green and white in colour,[5] sometimes with a hint of brown along the back and head.
