Description
Pristidactylus torquatus is a robust lizard with strong legs and a large head. The back is generally reddish-brown with large patches of grey and there is a dark collar around the throat. The underside is paler and the region round the vent is greenish-yellow. This lizard grows to a snout-to-vent length of about 6 to 11 cm (2.4 to 4.3 in).[2]
Distribution and habitat
Pristidactylus torquatus is endemic to Chile where it is found on the west side of the Andes between 35° and 42° south. The regions in which it is found are Biobío, La Araucania and Los Lagos. Its natural habitat is the extensive southern beech forests (Nothofagus) that grow in this temperate climate.[1]
Behaviour
Pristidactylus torquatus is a terrestrial species and is found mainly on the ground under the forest trees. It feeds chiefly on beetles which it chews up with its strong jaws. The female lays a clutch of about six eggs in a hole in the sand.[2]
Status
The IUCN has listed Pristidactylus torquatus as being of "Least Concern" because of its wide range and the lack of any identified threats to the species. Although the Nothofagus forests are being felled, they are being replaced by stands of Eucalyptus and this does not seem to have adversely impacted the lizard.[1]
