Palleon nasus

Palleon nasus, commonly known as the elongate leaf chameleon, is a species of chameleon endemic to Madagascar. It was initially described by Boulenger in 1887. The species contains two subspecies, P. n. nasus and P. n. pauliani. It grows no more than 9 cm.

Distribution and habitat
Palleon nasus nasus is endemic to Ekongo, south-eastern Madagascar, and its geological type locality is Ekongo, southeastern Madagascar. P. n. pauliani is only known from its type locality of Manjarivolo, l’Andringitra, Madagascar. P. n. pauliani can be found at elevations between 1620 and 1650 m above mean sea level. P. nasus was listed by the IUCN as a vulnerable species, as it can be found over an area of 15798 sqkm, but the quality and extent of the humid forest where the species needs to live is in a continuous decline, mainly due to mining, logging (for charcoal), and the slash-and-burn method in agriculture. P. n. nasus is found in some strictly protected areas and reserves, meaning it should not be harmed too much.

Taxonomy
Palleon nasus nasus was initially described as Brookesia nasus in 1887 by Boulenger and reclassified as a Palleon species in 2013. In 1972, the subspecies P. n. pauliani was described and recorded by Brygoo, Blanc, and Domergue in 1972. Palleon nasus is commonly known as the elongate leaf chameleon.
