Article
Full-text available
Apostolepis is a diverse genus of dipsadid snakes, currently comprising 34 species occurring in most cis-Andean South America. The taxonomy of the group is highly unstable. Upon discovering its type series, we redescribe the rare species A. ambiniger (Peters, 1869) and provide an account of its geographic distribution and morphological variation in...
Article
We describe a new species of the Gonocephalus megalepis group and provide new morphological and distribution data for the three other species of the group. The combination of a wide gap between the nuchal and dorsal crests, distinctly heterogenous scales on the flanks, a gular crest, two large tubercular scales ventral to the tympanum, and 97–125 s...

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 fr...

We review morphology and systematics of Phoxophrys using new specimens of previously rare species. In addition to external characters, we relied heavily on skull morphology visualized using computed tomography data of all currently recognized species in this genus. Phylogenetic analysis of ND4, 12S, and 16S mDNA sequences reveal that Ph. tuberculat...
Article
Full-text available
With the use of a concordance and a mitochondrial tree-morphological character congruence approach, we show that recently discovered populations of Lophocalotes represent a new species. Like its only known congener, the new species occurs only on Sumatra in montane forests above 1000 m. The new species differs from L. ludekingi in having more gular...
Article
Full-text available
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....

This paper is the first taxonomic treatment of Sumatran Philautus since the early 20th century. We redescribe P. cornutus and P. petersi from new specimens, restrict P. petersi to Great Natuna Island, and reinstate the name P. larutensis for the populations on Borneo, Peninsular Malaysia, and Sumatra. We then synonymize P. similis with P. larutensi...
Article
Spinicauda sumatrana sp. nov. is described from the large intestine of Ludeking’s Crested Dragon, Lophocalotes ludekingi (Agamidae) from the Bukit Barisan Range of Sumatra. The new species is assigned to Spinicauda based on the presence of off-set lips in both male and female and a ventrally directed sucker combined with the absence of caudal alae...
Article
Full-text available
We describe a new species of Pseudocalotes from montane forests of the central, western coast of Sumatra. The combination of 3 or 4 interoculabials, slightly enlarged and heavily keeled scales on the lower flanks, a white scapular spot, a relatively long fifth toe, bicarinate lamellae at the base of Toe III, absence of a postrictal modified scale,...

We describe a new genus and two new species of toads from the Sumatran volcanoes Gunung Sorikmarapi and G. Kunyit, in the provinces of Sumatera Utara and Jambi, respectively. The new taxa can be distinguished from other genera, and each other, based on genetic differentiation, morphology, and advertisement call structure. We employ both nuclear and...
Article
Full-text available
IUCN Red List assessments are important for conservation and management initiatives. However, status assessments are often challenging because of poor sampling between biogeographical regions. Researchers sometimes assess poorly known species, which can have unforeseen ramifications, including the trade of rare and cryptic species under common spec...
Article

We redescribe Cyrtodactylus lateralis (Werner) on the basis of new specimens. Cyrtodactylus lateralis is a prehensiletailed species, known from scattered lowland to mid-elevation localities in northern Sumatra. The prehensile-tailed Cyrtodactylus are more speciose and have a wider distribution than previously thought. This group includes a mainland...
Article
Full-text available
We describe Cyrtodactylus psarops sp. nov. and C. semicinctus sp. nov., two new species of bent-toed geckos from montane forests in the southern Bukit Barisan Range of Sumatra, Indonesia. The new species are closely related to one another and to C. semenanjungensis, a lowland species currently known only from Peninsular Malaysia. Three characters o...

We describe a new species of Cnemaspis from southern Sumatra, Indonesia. The new species is the first Cnemaspis reported from Sumatra and is a large (52.6–58.7 mm in snout–vent length [SVL]) nocturnal species. A combination of the following characters distinguishes the new species from all other Southeast Asian congeners: adults reaching 58.7 mm SV...

The Indonesian island of Sumatra contains several endemic species of parachuting frog of the genus Rhacophorus. Most of these are known from small type series collected from only a few localities, and consequently, many Sumatran Rhacophorus species are poorly understood. Using mitochondrial DNA (mtDNA), we investigated relationships among a group o...

We describe three new species of Pseudocalotes from the Bukit Barisan Range of southern Sumatra, Indonesia. Pseudocalotes cybelidermus, P. guttalineatus, and P. rhammanotus differ from most congeners in having serrate dorsal crests that extend to the base of the tail and a dorsolateral series of enlarged heavily keeled scales. In these new species,...

Despite advances within particular groups, systematics of the Teiidae has long been unsatisfactory, because few morphological characters have been described for this family. Consequently, most species have been assigned to the large, polyphyletic, and poorly defined genera Ameiva and Cnemidophorus. We describe 137 morphological characters and score...
