|Higher Taxa||Agamidae (Draconinae), Sauria, Iguania, Squamata (lizards)|
|Synonym||Calotes goetzi WAGNER, IHLOW, HARTMANN, FLECKS, SCHMITZ & BÖHME 2021|
|Distribution||Cambodia, China (Yunnan province), Laos, Myanmar, and Thailand (most of the previous range of C. mystaceus)|
Type locality: Cambodia, Siem Reap Province, near Kbal Spean within the Phnom Kulen National Park [13.699167° N, 103.998611° E].
|Reproduction||oviparous. Eggs are buried in soft soil and later guarded by the males (Wagner et al. 2021).|
|Types||Holotype: ZFMK 92606 (adult male, Fig. 7A-C, Clade A).|
Paratypes: ZFMK 88341 (adult male), ZFMK 92607 (adult female) from the same locality as the holotype.
|Diagnosis||Diagnosis: A large species of Calotes, with a maximum SVL of 143 mm in males and 122 mm in females. It can be distinguished from other species of the group by the combination of the following characters: 1) head, body and limbs robust, tail long but not as long as in C. mystaceus; 2) body scales mid-sized, homogeneous, keeled, arranged in regular rows; 3) upper dorsolateral scales pointing up- and backwards; 4) body scales arranged in 45–60 rows around midbody; 5) two short and separated spines, surrounded by a ring of scales between the tym-panum and the vertebral crest on both sides of the head; 6) vertebral crest continuous from above the tympanum to the hind limbs, composed of erected scales, directed posteriorly, highest slightly in front of the insertion of the front limbs, becoming gradually shorter towards the hind limbs; 7) vertebral scales, including vertebral spines, 37– 52 in males and 43–60 in females; 8) oblique skin fold in front of the fore limbs; 9) head, body, and limbs bluish in males; 19) males with a white stripe from between nostril and orbit along the upper lip and the tympanum to the front limb insertion; 11) three to five distinct dark brown dorsolateral blotches. (Wagner et al. 2021).|
Color in life: Head, body and limbs bluish. A white stripe, as high as the tympanum, is present from between nostril and orbit along the upper lip and the tympanum to the insertion of the front limb. The stripe is followed by three to five large reddish-brown to dark-brown blotches, with the first above the insertion of the fore limbs and the latest at around midbody or above the insertion of the hindlimbs, sometimes continuing on the tail. Throat coloration darker than the chin and the head coloration. From Thailand, males are known to have bright blue hindlimbs and crest scales. Intermediate males with a blue head and a white stripe, but body coloration brownish-black with indistinct light brown blotches. Non-brilliant coloration in males from Thailand reddish-brown, with a white non-continuous stripe from the orbit to above the hindlimbs. Blotches brownish, darker than the body coloration. (Wagner et al. 2021).
|Comment||Parasites: Recognized helminths are Abbreviata achari, Meteterakis singaporensis and Strongyluris calotis (Goldberg et al. 2021).|
Ecology. Calotes goetzi sp. n. is diurnal and semi-arboreal to arboreal and can easily climb on tree trunks at a height of 5–10 meters or above. The species is known from dipterocarp lowland forests, cultural landscape and secondary forest. At its type locality the species was ob- served in more open habitats with a closed canopy, but also within dense monsoon tropical forests and solitary trees in rather open areas. Here it occurs sympatrical- ly with Calotes versicolor. Hawkeswood & Sommung (2018) report it from farmland with e.g., rice, coconut, banana, and durian plantations. Chan-Ard et al. (2015) report the species from a wide range of forest types in Thailand, including tree-lined agricultural lands and grasslands. Similar to other Calotes species, C. goetzi sp. n. feeds on a variety of arthropods. Chan-Ard et al. (2015) report from Thailand, that mature individuals are territorial, chasing away possible intruders. Amber et al. (2017) recognized a possible ontogenetic shift in defense strategies of C. goetzi sp. n. (C. mystaceus at the time of their publication), with older individuals utilizing color change, while juveniles do not (Wagner et al. 2021).
|Etymology||The specific epithet is a patronym formed in the genitive singular honoring Dr. Stephan Goetz, Munich, Germany, in recognition of his longtime support of species conservation efforts in Cambodia.|
