Calumma crypticum, commonly known as the cryptic chameleon or blue-legged chameleon, is a species of chameleon found in eastern Madagascar.[2][1][3][4]
This species was first described in 2006 as Calumma crypticum by Raxworthy & Nussbaum, one of six new species from mountain regions of Madagascar.[5] It is very similar to, and was previously included in, the short-horned chameleon (Calumma brevicorne), but in 2007, Boumans et al. confirmed that it was sufficiently genetically distinct to be considered a valid species.[1]
Calumma crypticum grows to a length of about 12 cm (5 in) and has large flap-like lobes at the back of the head. The species is sexually dimorphic, the male having a longer snout with a horn-like protrusion on its upper surface, which the female lacks. As with other chameleon species, the colour is variable, depending on the colour of the surroundings, the ambient temperature, and variations in the level of light, but this species is usually quite colourful with rich browns, blues and greens, and the legs are often marked with blue.[6]
Calumma crypticum is endemic to eastern Madagascar where it is a mid-altitude species occurring between 1,050 and 1,850 m (3,445 and 6,070 ft) above sea level. Its range extends from the Tsaratanana Massif and the Ivakoany Massif. It is an arboreal species, living in humid forests; its distribution is patchy because of forest clearance on the central highlands between the mountain blocks, but there is a subpopulation around Ambohitantely in the central west of the island.[1]
This chameleon has a widespread distribution and occurs in a number of protected areas. Suitable habitat is being cleared for agriculture and the population is gradually declining, however the species is sufficiently common that the International Union for Conservation of Nature has assessed its conservation status as being of least concern.[1]

Calumma crypticum est une espèce de sauriens de la famille des Chamaeleonidae[1].
Cette espèce est endémique de la région d'Analamanga à Madagascar[1]. Elle se rencontre dans la réserve spéciale d'Ambohitantely.
Calumma crypticum se distingue des autres caméléons du genre Calumma par la présence d’un seul appendice rostral osseux pour les mâles, pouvant se projeter jusqu’à 2,4 mm en avant de la bouche, une longueur sans la queue de d’une centaine de millimètres, une paire de grands lobes occipitaux, et une coloration de la tête brun rougeâtre pour les mâles adultes.
Calumma crypticum est très similaire à Calumma amber, mais se distingue de celui-ci par la forme de la crête dorsale chez la femelle et la couleur de la tête et du corps chez les mâles.
L’épithète spécifique de cette espèce a été choisi en référence au statut cryptique de cette espèce.

Calumma crypticum Raxworthy & Nussbaum, 2006 è un piccolo sauro della famiglia Chamaeleonidae, endemico del Madagascar.[2][3]
È un camalonte di media taglia, lungo sino a 11 cm, con livrea rosso-brunastra. Il maschio presenta una singolo corno osseo rostrale, lungo sino a 2,4 mm, appiattito in senso dorso-ventrale, e due lobi occipitali uniti dorsalmente, lunghi sino a 3 mm.[2]
La specie ha un ampio areale che si estende da nord a sud lungo tutto il versante orientale del Madagascar[1]; una subpopolazione, isolata dal resto dell'areale, è stata segnalata all'interno della Riserva speciale di Ambohitantely[3].
Il suo habitat tipico è la foresta pluviale, ad altitudini comprese tra 1.050 e 1.850 m.
La IUCN Red List classifica Calumma crypticum come specie a basso rischio (Least Concern).[1]
La specie è inserita nella Appendice II della Convention on International Trade of Endangered Species (CITES).[4]
