|Types||Syntypes: NRM (2 specimens; fide ANDERSSON 1900: 13).|
Holotype: NHMB [saharicus]
|Comment||Subspecies: Chamaeleo chamaeleon arabicus and C. c. zeylanicus have been elevated to species status. Chamaeleo chamaeleon calcarifer is now C. calyptratus calcarifer. Chamaeleo chamaeleon has been reported from the Canary Islands but these are most likely escaped pets that do not form viable populations (A. Vilado, pers. comm.). Not present on Sicily as sometimes reported.|
Distribution: not in Iran fide SMID et al. 2014 (checklist Iran).
Type species: Chamaeleo parisiensium Laurenti 1768 is the type species of the genus Chamaeleo Laurenti 1768.
The genus Chamaeleo has been redefined by TILBURY & TOLLEY (2009) who elevated members of the subgenus Trioceros to full generic status. See Ch. oweni for a definition of Trioceros.

Diagnosis (genus): Apart from occipital lobes in some species and prominent parietal crests in others, they have little other head ornamentation. None of them possess horns or any form of rostro-nasal or pre-orbital projections. A gular-ventral crest of single cones is found in all species being more or less developed in the various forms from very prominent in Ch. calyptratus to almost indiscernible in Ch. namaquensis. None of the species of this genus demonstrate a temporal crest. The casque is edged in a lateral parietal crest originating as a posterior continuation of the supra-orbital ridge which delineates the posterior ramus of the squamosal bone. The temporal zone is undivided. The background scalation of the flanks is generally composed of relatively homogeneous to finely heterogeneous closely packed granular tubercles. The tail of all species within this group is smooth. The plantar surfaces are smooth and claws simple. This is the only genus where the presence of tarsal spurs is seen in several of the species (Ch. arabicus, Ch. monachus, Ch. chamaeleon, Ch. necasi, Ch zeylanicus, Ch. dilepis, Ch. gracilis, Ch. calyptratus, Ch. africanus). These tend to be best developed in males and usually absent or much reduced in females. Tarsal spurs may be a synapomorphy for the genus Chamaeleo. The basic internal lung morphology consists of two large septae arising from the region of the hilum of the lung which end freely within the lung, dividing it into three chambers viz a small dorsal, a large middle and a small ventral chamber. All species possess a gular pouch and in the lung - a membrano-fibrous diaphragm that partially separates off a small dorso-cranial compartment. Many species also have several small partial septae that arise from the dorsal wall of the lung near the cranial end. The lungs are invariably adorned with varying numbers of diverticulae that trail from the inferior and posterior margins of the lung. The diverticulae vary in length and number and may be branched (Klaver 1973, 1977, 1981). Hemipenes are calyculate, with a multi rotulae arrangement of between three to five pairs of denticulated rotulae except for Ch. arabicus and Ch. namaquensis which have retained the plesiomorphic four rotulae (two pairs) configuration (Klaver & Böhme 1986). The genus is oviparous with a cyclic reproductive strategy – usually a single brood but up to three clutches of eggs per year in some species in ideal conditions. These species tend to have relative longevity. Females are usually sexually mature within one year and over the next few years will produce at least one clutch of eggs annually. The parietal peritoneum is unpigmented. The documented karyotype of the several species so far examined (Matthey 1931, 1957, Matthey & van Brink 1956) is 2n=24=12M+12m and appears to be restricted to this genus as a synapomorphic character (Klaver & Böhme 1986) [from TILBURY & TOLLEY 2009).
|Etymology||The genus has been named after Greek “khamai” = on the ground and “leon” = lion: ground lion.|
