Laemanctus is a genus of lizards in the family Corytophanidae. Species in the genus Laemanctus are commonly referred to as conehead lizards or casquehead iguanas. The genus is endemic to Central America. [1]
Lizards of the genus Laemanctus exhibit the following characters. The tympanum is distinct. The plane of the top of the head slopes forward, and the occipital region is raised and extends beyond the occiput. The body is laterally compressed, and is covered with imbricate keeled scales. A strong transverse gular fold is present, but a gular pouch is absent. The limbs are very long, and the infradigital lamellae have a median tubercle-like keel. Femoral pores are absent. The tail is very long, and is round in cross section. The lateral teeth are tricuspid, and pterygoid teeth are present. The clavicle is loop-shaped proximally. A sternal fontanelle is absent. Abdominal ribs are absent. [2]
The genus Laemanctus consists of four species which are recognized as being valid. Two of these species have recognized subspecies. [3]
Corytophanidae is a family of iguanian lizards, also called casquehead lizards or helmeted lizards, endemic to the New World. Nine species of casquehead lizards from three genera are recognized.
Pachydactylus is a genus of insectivorous geckos, lizards in the family Gekkonidae. The genus is endemic to Africa, and member species are commonly known as thick-toed geckos. The genus also displays rich speciation, having 57 distinct species identified when compared to other closely related gecko genera like Rhoptropus, most of which have emerged since 35Ma. It has been suggested that the reason for this rich speciation not from adaptive radiation nor nonadaptive radiation, but that the genus represents a clade somewhere between the two drivers of speciation. P. bibronii geckos have been used by NASA as animal models for experimentation.
Ceratophora is a genus of agamid lizards found in Sri Lanka. The male has a horn on its snout.
Ctenosaura is a lizard genus commonly known as spinytail iguanas or ctenosaurs. The genus is part of the large lizard family, Iguanidae and is native to Mexico and Central America. The name is derived from two Greek words: ctenos (κτενός), meaning "comb", and saura (σαύρα), meaning "lizard".
Corytophanes is a genus of Neotropical lizards, commonly referred to as helmeted iguanas or helmeted basilisks, in the family Corytophanidae. The genus contains three species, all of which are arboreal, and reside in tropical forests.
Spiny lizards is a common name for the genus Sceloporus in the family Phrynosomatidae. The genus is endemic to North America, with various species ranging from New York, to Washington, and one occurring as far south as northern Panama. The greatest diversity is found in Mexico. This genus includes some of the most commonly seen lizards in the United States. Other common names for lizards in this genus include fence lizards, scaly lizards, bunchgrass lizards, and swifts.
Typhlosaurus is a genus of African lizards, one of a number of genera of limbless lizards in the skink family (Scincidae). This group was recently revised with most species formerly attributed to Typhlosaurus now placed in Acontias. The current definition of Typhlosaurus includes five attenuate body legless lizards from southwestern Africa. This is the sister genus to Acontias, which together form the well supported Afrotropical subfamily Acontinae.
Diploglossus is a genus of New World diploglossid lizards, with 20 described species, commonly known as galliwasps.
Ctenosaura pectinata is a species of moderately large lizard in the family Iguanidae. The species is native to western Mexico.
Sceloporus variabilis, commonly known as the rosebelly lizard, is a species of lizard, which is endemic to Mexico.
The eastern casquehead iguana is a species of lizard in the family Corytophanidae. The species is native to Mexico and Central America.
Wiegmann's tree lizard, Anisolepis undulatus, is a species of lizard in the family Leiosauridae. The species is endemic to South America.
Stenocercus is a genus of South American lizards, commonly called whorltail iguanas, of the family Tropiduridae. This genus has 76 valid described species.
Fitzinger's algyroides, also called the pygmy algyroides or the pygmy keeled lizard, is a species of lizard in the family Lacertidae.
Abronia deppii is an endangered species of arboreal alligator lizard in the family Anguidae. The species was described in 1828 by Arend Friedrich August Wiegmann, and it is endemic to Mexico.
Crossobamon eversmanni, known commonly as the comb-toed gecko, is a species of Asian gecko, a lizard in the family Gekkonidae.
Aspidoscelis deppii, known commonly as the blackbelly racerunner, is a species of lizard in the family Teiidae. The species is native to Central America and southern Mexico. There are three recognized subspecies.
Cercosaura schreibersii, known commonly as Schreibers's many-fingered teiid or the long-tailed little lizard, is a species of lizard in the family Gymnophthalmidae. The species is endemic to South America.
Laemanctus waltersi, also known commonly as Walters' casquehead iguana or Walters's casquehead iguana, is a species of lizard in the family Corytophanidae. The species is endemic to Honduras.
