HARVEY, M.B., SHANEY, K., SIDIK, I., KURNIAWAN, N. & E.N. SMITH (2017): Endemic dragons of Sumatra’s volcanoes: New species of Dendragama (Squamata: Agamidae) and status of Salea rosaceum Thominot. - Herpetological Monographs 31 (1): 69–97. We discovered new populations of Dendragama at the northern and southern ends of Sumatra. High genetic distances and concordance of multiple, apparently independent diagnostic characters support our descriptions of these two populations as new species. We define new characters of the sublabial, tympanic, dorsal crest, and dorsolateral crest scales. The three species of Dendragama undergo remarkable color change in response to time of day and stress. Females lay 2–4 ovoid eggs, reach sexual maturity at about 60 mm snout–vent length, and likely produce multiple clutches each year. We remove Salea rosaceum Thominot from the synonymy of Dendragama boulengeri and argue that the unique holotype of S. rosaceum is a specimen of Pseudocalotes tympanistriga with incorrect locality information.

Schneider’s Tree Agama AHL, E. (1926): Ahl, E. 1926. Neue Eidechsen und Amphibien. Zool. Anz. 67: 186-192 SHANEY, K.J., HARVEY, M.B., HAMIDY, A., KURNIAWAN, N. & E.N. SMITH (2020): Phylogeny and biogeography of Sumatra’s cloud forest lizards oft he genus Dendragama and the status of Acanthosaura schneideri. – ZooKeys 995: 127-153. Lizards of the genus Dendragama are endemic to the highland cloud forests of Sumatra’s Barisan Mountain Range in western Indonesia, and recent studies have uncovered widespread diversity within the genus. Here, a suite of morphological characters and mitochondrial DNA are used to compare three geographi[1]cally isolated populations of D. boulengeri from (1) Mount Kerinci in Jambi province, (2) Mount Marapi of west Sumatra, and (3) the Karo Highlands of north Sumatra. Additional phylogeographic analyses with two recently described sister species, D. australis and D. dioidema were conducted. Five genetically distinct clades of Dendragama, all distributed allopatrically of one another were identified and some are suspected to inhabit small distributions. Morphological and genetic data confirm the Karo Highlands population D. schneideri (previously Acanthosaura schneideri Ahl, 1926) should be revalidated from the synonymy of D. boulengeri. Dendragama schneideri is endemic to montane forests of the Karo Highlands surrounding Lake Toba in Sumatra Utara province. Pairwise genetic distances of 6–11% separate D. schneideri from congeners. Two distinct clades of D. boulengeri from Mount Kerinci and Mount Marapi were identified, which are 5.0% genetically distant from one another. Using morphological characters, we provide the first key for distinguishing between species of Dendragama. Based on biogeographic patterns and levels of genetic variation it is suspected that at least 18 other isolated cloud forest locations may hold new species or divergent populations of Dendragama but lack survey work. Collectively, these comparisons among populations of montane lizards further elucidate the complex biogeog. |
