Calumma is a genus of chameleons, highly adapted and specialised lizards, in the family Chamaeleonidae. The genus is endemic to the island of Madagascar. One species, formerly known as Calumma tigris (the Seychelles tiger chameleon), was transferred to the genus Archaius in 2010, upon the discovery of its closer relation to Rieppeleon—one of several genera referred to collectively as "leaf" or "pygmy" chameleons—rather than to Calumma.[1] The earliest known fossil of the genus is of Calumma benovskyi, from early Miocene Kenya, showing that the genus likely originated on mainland East Africa.[2] The genus includes one of the heaviest and longest chameleon species, the Parson's chameleon (Calumma parsonii).[3]
