“…This interpretation likely explains apparent rarity of some Harpesaurus. Harpesaurus modiglianii Vinciguerra (1933) was known only from the holotype collected in 1891 until Putra et al (2020) discovered a population of these rare lizards near Lake Toba, North Sumatra. Putra et al (2020) found their new specimen 4 m aboveground on a horizontal branch, sufficiently high in the forest that it might have been overlooked by most herpetologists.…”

We review morphology of Sunda Shelf Gonocephalus with an emphasis on Sumatran and Javan species. At least 15 species and subspecies inhabit Peninsular Malaysia, Sumatra, Java, Borneo, and adjacent smaller continental islands. Following analysis of external morphology, we provide a dichotomous key to Sunda Shelf Gonocephalus and resolve two taxonomic problems with this group of lizards. Three populations of Gonocephalus doriae on Borneo, Peninsular Malaysia, and Sumatra are recognized as subspecies, because they lack concordance of multiple morphological differences and have low genetic divergence in a 556 base-pair fragment of the 16S rRNA gene. Described as new herein, G. doriae brevis from Aceh and North Sumatra differs from G. d. abbotti and G. d. doriae in usually having more scales around midbody and a relatively shorter tail with fewer dark bands. Though previously reported as lost, a syntype of G. d. doriae (MSNG 29152) is designated as lectotype, illustrated, and described. Also described as new, G. inauris from high elevations of the Bukit Barisan Range of Bengkulu, Sumatra, is a species of the G. megalepis Group differing from all congeners in having 7/6 (vs. 8-19) loreals separating the last canthal and supralabials, 8/8 (11-27) infraorbitals, and 58 (73-153) scales around midbody. In this new species, distinctly enlarged suboculars broadly contact its supralabials, whereas 1-4 lorilabials separate the suboculars and supralabials in congeners. High genetic divergence in the new species mirrors its high level of morphological divergence.

“…However, Sumatra’s cloud forest biodiversity has remained largely unexplored and the pressures that have driven the development of that diversity are not yet fully understood ( O’Connell et al 2018 ). Reptilian diversity is no exception in this regard despite the fact that Sumatra is known to harbor some of the most evolutionarily unique lineages of reptiles, including enigmatic species like the Modigliani’s nose-horned lizard which was recently rediscovered ( Putra et al 2020 ).…”

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.
