“…the methods, we confirmed each of these morphometric differences by treating other measurements as covariates. Moreover, a separate sample of nine Dendragama from Kerinci had relatively shorter tails (F 1,27 = 7.75, P = 0.010) than the sample of D. boulengeri from both Marapi and the type locality described by Harvey et al (2017). We did not find differences among populations for eye-nostril distance, pectoral width, length of body, length of shank, length of brachium, length of antebrachium, or internarial distance (P > 0.12).…”

“…It's important to note that individuals from the Karo Highlands were not collected precisely from the type locality of A. schneideri but were found in nearby geographic locations. We then combined new sequences from these specimens with sequences already published by Shaney et al (2016) and Harvey et al (2014Harvey et al ( , 2017 on GenBank. The published sequences include the outgroup taxa Bronchocela cristatella (Kuhl, 1820), Lophocalotes ludekingi (Bleeker, 1860), and Pseudocalotes tympanistriga (Gray 1831) see Suppl.…”

“…They may also use their colors when competing with other individuals. Although little is known about the life cycles of D. schneideri specifically, Harvey et al (2017) suggest that other species of Dendragama reach maturity at around 60 mm, females lay 2-4 ovoid eggs and probably produce multiple clutches each year. This may also be true for D. schneideri given their other similarities in life histories.…”

“…There has been considerable uncertainty regarding the taxonomic status of Dendragama boulengeri, which was considered to belong to a monotypic genus until only recently (Harvey et al 2017). Early studies reported D. boulengeri from isolated montane forests of Jambi, west Sumatra (Sumatra Barat) and north Sumatra (Sumatra Utara) provinces (Doria 1874).…”

“…Early studies reported D. boulengeri from isolated montane forests of Jambi, west Sumatra (Sumatra Barat) and north Sumatra (Sumatra Utara) provinces (Doria 1874). However, Harvey et al (2017) recently described two new species, D. australis from south Sumatra and D. dioidema from Aceh Province. They also provide a thorough redescription of D. boulengeri.…”

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 geographically 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 biogeographic history of Sumatra’s montane forest species and the first phylogeny of the genus Dendragama.
