description: <i>Calotes goetzi</i> sp. n. (Fig. 2, Clade A) <i>urn:lsid:zoobank.org:act: 7827D48E-E121-4904-9636-3A46AE42B369</i> <b>Holotype.</b> ZFMK 92606 (adult male, Fig. 7 A-C, Clade A) from Cambodia, Siem Reap Province, near Kbal Spean within the Phnom Kulen National Park [13.699167° N, 103.998611° E]. <b>Paratypes.</b> ZFMK 88341 (adult male), ZFMK 92607 (adult female) from the same locality as the holotype. <b>Diagnosis.</b> Alarge species of <i>Calotes</i>, 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 <i>C. mystaceus</i>; 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 tympanum 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. <b>Description of the holotype.</b> Large male (SVL 118 mm). Body robust, tail relatively short, 236 mm long. Fore- and hind limbs relatively slender, fourth finger and toe longest. Head distinct from the neck, posterior jaw angles heavily swollen. Tip of the snout blunt, rostral small. Nostril large, in a single scale, separated from the rostral by one elongated scale and from the first two supralabial scales by two rectangular scales. Canthus rostralis distinct, formed by nine scales from the nostril to above the orbit and continuous with supraciliary scales. Lateral sides of the head flat. Supralabial scales 9/9, infralabial scales 10/10. Supralabial scales separated from the orbit by four rows of small scales. Eight scales between the orbit and the tympanum, two of them slightly ridged. Tympanum distinct, two spines, surrounded by a ring of scales, between the tympanum and the vertebral crest. Mental scale small, bordered by two postmental scales which are separated from each other. First pair of the postmental scales in contact with the infralabial scale. Scales on the dorsal part of the chin smooth to feebly keeled, becoming strongly keeled towards the throat. Vertebral crest continuous from above the tympanum to the tail, spines highest above the insertion of the front limbs and gradually decreasing towards the tail. Dorsal and lateral scales strongly keeled, pointing up- and backwards. Ventral scales parallelly keeled. Caudal scales smooth to feebly keeled, directed backwards. Subcaudal scales parallel and strongly keeled. <b>Male coloration.</b> Head, body and limbs bluish. Awhite 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. <b>Variation.</b> Bodymeasurements and meristic characters for adult individuals are given in Tables 4. Specimens ranged in size between the smallest adult with a SVL of 84 mm (MNHN 1884.548) and the largest female with a SVL of 126 mm (ZFMK 44893) to the largest male measuring 145 mm (MNHN 1884.546). In general, adult males are larger than females, because of longer SVLs, tail lengths, head lengths, and widths and slightly fewer vertebral scales including the crest scales. Heads of adult males and females are proportionally equal in length, but male heads are wider than those of females, probably because of the swollen jaw angle. Dorsal coloration differs between sexes and both sexes are able to change the coloration. Coloration characters being lighter in females; head and body blue. Lateral stripe from between the nostril and orbit along the upper lips and the tympanum to the first blotch. Sometimes the first two brownish blotches are framed by scales in the same coloration as the lateral stripe. Three to five blotches present, from above the insertion of the fore limbs to about mid-body or even hindlimb insertion. Non-display coloration of females with lateral parts of the body gray and dorsal parts brown, with three to four darker crossbands between the lateral stripes on both sides of the body. Lateral stripe white, from the mental scale along the upper lips and the tympanum to the hindlimbs. Head light blue. <b>Etymology.</b> 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. <b>Distribution.</b> <i>Calotes goetzi</i> sp. n. is distributed in a large area of Indochina and inhabits most of the previous range of <i>C. mystaceus</i>. The new species is documented by museum specimens and photo vouchers from Cambodia, China (Yunnan province), Laos, Myanmar, and Thailand. <b>Ecology.</b> <i>Calotes goetzi</i> 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 observed 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 sympatrically with <i>Calotes versicolor</i>. Hawkeswood &amp; 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 <i>Calotes</i> species, <i>C. goetzi</i> 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. Eggs are buried in soft soil and later guarded by the males. Amber et al. (2017) recognized a possible ontogenetic shift in defense strategies of <i>C. goetzi</i> sp. n. (<i>C. mystaceus</i> at the time of their publication), with older individuals utilizing color change, while juveniles do not.
