Brookesia is a genus of chameleons, lizards in the family Chamaeleonidae. The genus is endemic to Madagascar. Member species range from small to very small in size, and are known collectively as leaf chameleons (though this common name is also used for species in the genera Rieppeleon and Rhampholeon ). Brookesia includes species considered to be the world's smallest chameleons, and are also among the smallest reptiles. Members of the genus Brookesia are largely brown, and most are essentially terrestrial.

Contents

A significant percentage of the species in the genus were only identified to science within the last three decades, and a number of species that still have not received a scientific name are known to exist. Most inhabit very small ranges in areas that are difficult to access, and due to their small size and secretive nature, they have been relatively poorly studied compared to their larger relatives.

Brookesia are abundant in low-disturbance riparian zones [1] and low-disturbance rainforests. Brookesia are scarce in high-disturbance forests [2] recovering from burning. As of 2021, Brookesia nana is the most recently described new species in the subfamily Brookesiinae. B. nana is also the first chameleon known not to change colors.[ citation needed ]

Etymology

The generic name Brookesia is in honor of British naturalist Joshua Brookes. [3]

Conservation status

Most Brookesia are on CITES Appendix II, the only exception being B. perarmata on Appendix I (a species also listed as endangered and a newly discovered Brookesia nana listed as Critically Endangered [4] by IUCN). Consequently, a special permit is required to import any of the below species from their native Madagascar, and typically no permit is issued for B. perarmata.

The genus Brookesia contains the following 31 species which are recognized as being valid. [6]

<i>Calumma</i> Genus of lizards

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, 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. 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. The genus includes one of the heaviest and longest chameleon species, the Parson's chameleon.
