Agama lebretoni is a West African agama species that was only newly described in 2009. Their distribution area includes Cameroon , Gabon and theisland Bioko, which belongs to Equatorial Guinea .
features
Agama lebretoni is a comparatively large species of agamen; adult males can reach a total length of more than 25 to 35 centimeters. The tail is about 1.6 times as long as the head-torso length .
The head and body are equally small. The pupil is round, the nostrils are above the corners of the eyes. There are tufts of thorns around the ear opening and on the side of the neck. There is a neck comb, the back and tail comb are missing. The scales on the upper head are partly keeled, scales further back are keeled and prickly, while the ventral scales are smooth. The middle of the body has 73 to 80 rows of scales, along the back there are 42 to 54 scales. Males have preanal pores.
The head and neck of adult dominant males are deep red and orange, respectively. They have a reticulated pattern on the throat. The body, and occasionally the upper sections of the limbs, are sky to dark blue with white to yellowish mottles and a light line on the back along the spine. The tail is four-colored: blue at the base, white behind it, then red or orange and dark blue at the tip of the tail. The combination of throat and tail color is the diagnostic feature of the species.
Reproductive females and young animals are vividly drawn with yellow and black spots, stripes and bands on a gray-brown background, pregnant females turn inconspicuously brown with orange flanks. They can only be clearly distinguished from other females of the genus by molecular genetics.
Occurrence and way of life
The distribution area of Agama lebretoni extends from Cameroon , where the species is widespread, to Gabon and the Equatorial Guinean island of Bioko . However, there is no evidence for the mainland Equatorial Guinea . The species radiates from Cameroon to the Nigerian border region.
Agama lebretoni is a tree-dwelling species that lives in dense forests. Within its range, Agama lebretoni is very common and obviously a cultural follower, it can be found in cities, villages, along roads and in plantations.
Systematics
The species was first described in 2009 by Philipp Wagner , Michael F. Barej and Andreas Schmitz . The species epithet honors the Australian Matthew LeBreton for his services to research into the herpetofauna of Cameroon.
Agama lebretoni is closely related to the settler agama ( Agama agama ), their distribution areas overlap in northern Cameroon.
