We collected two specimens of an undescribed species of Lygosoma from pitfall traps in an urban rainforest in Kuching and from the base of a forested hill in western Sarawak, East Malaysia. The new species is diagnosable from all south-east Asian congeners by morphological characters, and most closely resembles Lygosoma herberti from the Thai-Malay Peninsula. The new species shows substantial molecular divergence from its closest relatives in two protein-coding genes, one mitochondrial (ND1) and one nuclear (R35) that we sequenced for several south-east Asian congeners. We describe the new species on the basis of this distinct morphology and genetic divergence. It is the third species of Lygosoma known from Borneo, and highlights the continuing rise in lizard species diversity on the island. In addition, the discovery of this species from a small urban rainforest underscores the importance of preserving intact rainforest areas of any size in maintaining species diversity.

A distinct new gecko of the genus Hemidactylus is described from the Meghamalai massif in Tamil Nadu, India. This large sized (average SVL 88.2±16.0 to at least 112.2 mm), cryptic, rock-dwelling species is superficially similar to its tuberculate South Asian congeners of comparable size, but can be distinguished from them in having 17–19 longitudinal rows of fairly regularly arranged, strongly keeled, striated tubercles with the two most medial parasagittal rows smaller, flatter, strongly keeled and rounded, increasing in size laterally and becoming strongly conical at the flanks; 8–10 and 10–12 sub-digital lamellae under the first and fourth digits respectively of both manus and pes; 17–22 femoral pores on each side separated medially by a diastema of 10–11 poreless scales; 11–15 supralabials and 9–14 infralabials. Molecular data supports the distinctiveness of this species and helps ascertain its phylogenetic position within the larger Indian Hemidactylus clade.

We here describe Sitana attenboroughii sp. nov., a new species of fan-throated lizard of the genus Sitana Cuvier, 1829 from coastal Kerala in southern India. The new species morphologically is closer to Sitana visiriDeepak, 2016 (in Deepak et al. 2016a), however, differs in having higher numbers of ventral scales and a comparatively short but richly colored dewlap. Genetically the new species shows affinity to Sitana marudhamneydhal Deepak, Khandekar, Varma & Chaitanya, 2016 from which it differs in an uncorrected pairwise sequence divergence of 2.2% for a fragment of mitochondrial Nicotinamide adenine dinucleotide dehydrogenase (NADH) subunit 2 gene.
Keywords: Reptilia, taxonomy, India, molecular phylogeny, mitochondrial DNA, Kerala

A new species, Cyrtodactylus durio sp. nov., is described from northwestern Peninsular Malaysia on the basis of its head, body, limbs, and tail being extremely spinose as well as other unique combinations of squamation and color pattern. It is proposed that C. durio sp. nov. forms a clade with C. brevipalmatus, C. elok, C. spinosus, and C. stresemanni on the basis of having a spiny, prehensile tail and that it is the sister species of C. stresemanni based on unique caudal tuberculation. Cytrodactylus durio sp. nov. is the latest in a growing list of new species of amphibians and reptiles recently described from the Malay Peninsula, and Peninsular Malaysia in particular, that clearly underscores the need for continuing exploratory research in these regions.
FIGURE 2. Holotype ZRC 2.9606 of Cyrtodactylus durio sp. nov.
Cyrtodactylus durio sp. nov.
Etymology. The specific epithet durio is in reference to the Latin generic name Durio for the durian fruits of Asia. It is derived from the Latin root dur, meaning hard or duable. Its application as the specific epithet herein is based on the similar spiny exterior of both the durian and the gecko.

We describe a new species of coralsnake from northern Dinagat Island, southeastern Philippines. The discovery of this new species comes as a surprise because it is phenotypically distinct from all other Philippine coralsnakes and has a close phylogenetic affinity to the blue coralsnakes of the Sunda Shelf. The new species is distinguished from all Philippine and other Southeast Asian taxa by its large body size and ventral scale counts; its black head and neck; an alternating, broadly banded color pattern of black and off-white; and a bright orange tail. We use DNA sequence data to investigate the phylogenetic placement of the new species and that of several other populations of Philippine coralsnakes with respect to other Southeast Asian and Australasian elapids. Our results corroborate the uniqueness of the new species with respect to all other Philippine and Sundaic taxa, including the species most closely related to it: Calliophis bivirgatus, C. bilineatus, C. philippinus, and C. suluensis. We summarize phylogenetic, biogeographic, and phenotypic character data that substantiate the elevation of Philippine species of Calliophis(formerly considered subspecies of C. intestinalis: C. bilineatus, C. philippinus, and C. suluensis) and Hemibungarus(formerly subspecies of H. calligaster: H. calligaster, H. gemianulis, and H. mcclungi) to the level of full species. The allopatric distributions of these taxa emphasize the systematic and biogeographical significance of the newly discovered taxon: a poorly understood and independent colonization of the Philippine Archipelago by elapid snakes.
Keywords:Calliophis salitan, Caraga Region, Mindanao PAIC, new species, false coralsnakes
Calliophis salitan adult male holotype (PNM 9844, formerly KU 310164; 997 mm total length [TL]), illustrated by E.F. Jones.
Calliophis salitan sp. nov.
Etymology.— The specific epithet is a noun in apposition and is derived from the Tagalog (Filipino) term salitan, meaning‘‘alternating,’’in reference to the distinctive, alternating black and off-white banded color pattern characteristic of the new species. Suggested English common name: Dinagat Island Banded Coralsnakes.
Habitat, distribution, and natural history.— The only known locality for Calliophis salitan is the low foothill of Mt. Cambinlia, Barangay Santiago, Municipality Loreto, Dinagat Island (Fig. 8), Philippines, where it was collected from an elevation of 195 m. This locality, dominated by selectively logged, regenerating second-growth forest, is situated at the northern end of the island, and has a tropical climate, with a mean annual precipitation of 3580 mm (recorded at Loreto town proper,,1 km from the type locality; higher precipitation values are possible at higher elevations on Mount Cambinlia). Precipitation is highest during December (~539 mm) and lowest in August (averaging 143 mm),and the mean annual temperature is 278C. The type specimen was collected between 1900 and 2200 h, and was actively crawling along a stream bed with reduced water flow between intermittent pools. The specimen was obtained at the end of July, toward the end of the dry season.

Marine iguanas are among the most highly emblematic taxa of the Galápagos archipelago but have paradoxically received little attention from taxonomists. Amblyrhynchus is currently considered as a monotypic genus with a total of seven subspecies, A. cristatus cristatus, A. c. nanus, A. c. venustissimus, A. c. albemarlensis, A. c. hassi, A. c. mertensi and A. c. sielmanni. Although consensually followed for more than half a century, this classification does not properly reflect the main natural subdivisions inferred by more recent molecular evolutionary studies. We integrate population genetics, phylogenomics and comparative morphology to propose an updated taxonomy reflecting the evolutionary history of this group. We recognize a single species with 11 divergent population clusters at the level of subspecies: A. c. albermarlensis is recognized as a junior synonym of A. c. cristatus, and five new subspecies are described:Amblyrhynchus cristatus godzilla subsp. nov. (San Cristóbal-Punta Pitt),A. c. jeffreysi subsp. nov. (Wolf and Darwin), A. c. hayampi subsp. nov. (Marchena), A.c. trillmichi subsp. nov. (Santa Fé) and A. c. wikelskii subsp. nov. (Santiago). Recognizing the genetically divergent population clusters as subspecies also highlights several of them as management units in need of conservation efforts, such as the two subspecies endemic to San Cristóbal.
Keywords: Amblyrhynchus, Galápagos, integrative taxonomy, management units (MUs), Marine Iguana, new subspecies.

Fig 8: Distribution of the different subspecies of Galápagos marine iguanas according to the classification of Eibl-Eibesfeldt (1962) and the new taxonomy proposed herein. The orange dot on the southern coast of San Cristóbal represents the population of putative migrant specimens of A. c. venustissimus.
Etymology: The subspecific epithet hayampi refers to the word used to designate the common iguana in Kichwa (a Quechuan language representing one of the three official languages of Ecuador and currently spoken by a million people in South America).
Geographic distribution: Marchena and very likely its satellite islets (Fig. 8).
Etymology: The subspecies name is a patronym for Jeffreys Málaga, a ranger of the Galápagos National Park with an outstanding interest and enthusiasm for the fauna and flora of the Galápagos, and especially for marine iguanas. Jeffreys Málaga has been awarded several times ‘Guardaparque del Año,’ or Park Warden of the Year and has been an essential part of our team during several excursions to the Galápagos.
Geographic distribution: Wolf, Darwin (tentative assignment), Roca Redonda and very likely their satellite islets (Fig. 8).
Etymology: The subspecific epithet refers to the fictional saurian monster from the eponym movie franchise, Godzilla, created by Tomoyuki Tanaka (IMDb, 2016). Explicitly mentioned in the title sequence of the 1990s American remake (Emmerich, 1998), the physical appearance and swimming behaviour of marine iguanas were a significant source of inspiration to the creature′s designer (Patrick Tatopoulos, personal communication). The name is an invariable noun in apposition.
Geographic distribution: Northern (north-eastern) part of San Cristóbal and the satellite islets off the northern coast of San Cristóbal (Fig. 8).
Etymology: The subspecific epithet refers to Prof. Dr. Fritz Trillmich, a foremost biological researcher in Germany who has spent a lifetime working on the biology of the Galápagos islands. For many years Fritz Trillmich worked together with Martin Wikelski on the island of Santa Fé, where their research on the local population produced important insights into the behaviour and ecology of marine iguanas. In addition to undertaking his own research, Fritz Trillmich is Professor Emeritus of Behavioural Ecology at the University of Bielefeld where he continues to inspire and mentor generations of young researchers who will continue his legacy for years to come.
Geographic distribution: Santa Fé and very likely its satellite islets (Fig. 8).
Etymology: The subspecies name is a patronym for Prof. Dr. Martin Wikelski in recognition of his outstanding research on marine iguanas for several decades. Martin Wikelski has been fascinated by marine iguanas, which served as a study system for his behavioural and ecological research from his PhD onwards. He has published important papers on marine iguana ecology and conservation, for instance demonstrating the devastating effects of an oil spill on this species, and showing that marine iguanas can shrink in response to starvation induced by El Niño–based climate fluctuations.
Geographic distribution: Santiago, Rábida and very likely their satellite islets (Fig. 8).

The island of New Guinea has been identified as biologically megadiverse but many taxa are still poorly known. This is especially the case for many of the island’s snakes, which by their very nature can be difficult to collect and study. Here we examine the phylogenetic and phylogeographic structure of a poorly studied snake genus, Stegonotus, focusing on the species of New Guinea; until now, Stegonotus has never been examined using modern phylogenetic methods. Using molecular data from 49 individuals representing eight of the ten described species, and including all New Guinea taxa, we estimate a multilocus phylogeny and examine population structure to help identify undescribed taxa. We use morphological data from the corresponding museum vouchered specimens (where available) and also examine additional specimens for taxa not included in the molecular data set to determine morphological differences among putative taxa. We find molecular evidence for four new species of Stegonotus, both morphologically obvious and cryptic, and describe them herein. The recognition of these four species indicates that Stegonotus diversity has been previously underestimated and also suggests that there are likely additional undescribed taxa within the genus. These four taxa increase the number of described species by 40% and further confirm New Guinea as the centre of diversity for the genus.

Stegonotus iridis sp. nov.
Etymology: The species epithet is a noun in apposition and taken from the Latin word for rainbow. It refers to the high level of iridescence shown both dorsally and ventrally by this species.
Natural history and distribution: Currently known only from the Raja Ampat islands of Batanta, Salawati and Waigeo in eastern Indonesia where all of the animals encountered were active on the forest floor in moderately to heavily disturbed lowland (< 100 m asl) rainforest at night. The pale colour of this species made them extremely conspicuous against the dark forest floor.
Stegonotus derooijae sp. nov. MZB.Ophi.3288
Photos from Stephen J. Richards.
Stegonotus derooijae sp. nov.
Etymology: The species epithet is a noun in the genitive case and is a patronym in honour of Dr Nelly De Rooij, who described many taxa from New Guinea and Indonesia, including Stegonotus florensis.
Natural history and distribution: Currently known only from the Raja Ampat islands of Batanta, Salawati and Waigeo in eastern Indonesia. This small, slender species was active on the forest floor in moderately to heavily disturbed lowland (< 100 m above sea level) rainforest at night. At each site it occurred in sympatry with S. iridis sp. nov., described above.
Stegonotus melanolabiatus sp. nov.
Etymology: The species epithet comes from the Greek melano meaning black or dark and the Latin word labia for lips. The name refers to the dark coloration of the labial scales of this species.
Natural history and distribution: No information is known about the natural history of S.melanolabiatus. Stegonotus melanolabiatus sp. nov. is found south of the central mountain ranges (Figure 3) in Southern Highlands and Chimbu Provinces of Papua New Guinea. It may also occur in other provinces and regions south of the central cordillera across New Guinea.
Stegonotus admiraltiensis sp. nov.
Etymology: The species epithet refers to the Admiralty Islands where this species is found, an archipelago of 18 islands to the north of New Guinea, comprising Manus Province, Papua New Guinea.
Natural history and distribution: As with all New Guinea Stegonotus, S. admiraltiensis sp. nov. is nocturnal. All four specimens were collected at night as they were moving on the forest floor on the leaf litter. Typical for Stegonotus, once picked up S. admiraltiensis sp. nov. rapidly attempted to bite the collector’s hand and writhed violently in a side-to-side motion. Nothing more is known about the natural history or ecology of S. admiraltiensis sp. nov. Stegonotus admiraltiensis sp. nov. is found on the islands of Rambutyo and Los Negros in Manus Province of Papua New Guinea. Based on descriptions of similar specimens from Manus (McDowell 1972) and recent collections there by SJR that will be registered in the near future (Richards and Aplin 2015), we conclude that S. admiraltiensis sp. nov. is also found on Manus Island proper and that all specimens of Stegonotus from the Admiralty Islands are S. admiraltiensis sp. nov.
