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 population of Japalura from Yunnan Province, China, previously assigned to Japalura splendida, is described as a new species. The new species has been recorded between 1138–2500 m in the Nu River drainage between the towns of Liuku and Binzhongluo, and on the lower western slopes of the Nushan and eastern slopes of the Goaligongshan. The new species can be distinguished from other species of Japalura, except J. dymondi, by the following combination of characters: exposed tympani, prominent dorso-lateral stripes, and small gular scales. It is very similar with but differs from J. dymondi by having smooth or feebly keeled dorsal head scales, three relatively enlarged spines on either side of the post-occiput area, strongly keeled and mucronate scales on occiput area and within the lateral stripes, back of arm and leg green, higher number of dorsal-ridge scales (DS) and fourth toe subdigital scales (T4S). A principal component analysis of body measurements of adult male specimens of the new species and J. dymondi showed principal component 1 loading highest for upper arm length, fourth toe length and snout to eye length and principal component 2 loading highest for head width, head length and fourth toe length.
Keywords: Agamidae, Japalura sp. nov., Goaligongshan Mountain, Nujiang River Valley, Hengduan Mountains, Yunnan, China
Japalura slowinskii sp. nov.
Diagnosis: A large species of Japalura with a robust head and body compressed dorso-ventrally; SVL = 89.6±5.44 mm (n = 18; Male); SVL = 83.9±6.71 mm (n = 7; Female); smooth or feebly keeled dorsal head scales; exposed tympani; a transverse gular fold; a distinct oblique fold anterior to shoulder extending dorsally from transverse gular fold and continuing posteriorly beyond shoulder; dorsal scales heterogeneous, larger scales strongly keeled; a broken dorso-lateral row of enlarged and strongly keeled scales separated from dorsal crest scales by one large or two smaller scales, and separated from each other by one or two small scales; tail in adult males slightly swollen posterior to base; dorsum of males black with a turquoise dosolateral stripe on either side of mid-dorsal crest: fore and hind limbs green.
Etymology: The specific epithet is a patronym honoring our late friend and colleague Joseph Bruno Slowinski. The epithet is a masculine noun in the genitive case. Dr. Joseph B. Slowinski worked in CAS until his death on September 11, 2001 in north Myanmar a bite from a krait during a field expedition at the age of 38 years old, when he was in charge of both the projects of Myanmar Biodiversity Survey, and the China Natural History Project — the NSF-funded Gaoligongshan Project (collaborative project between KIZ, KIB, and CAS).
Distribution and Natural History:Japalura slowinskii has only been found within the Nu River Valley drainage system between the town of Liuku, Liushu County, and the town of Binzhongluo, Gongshan County, a northsouth distance of approximately 210 km (refer to Figure 1). The species has been found on the western slopes of the Nu Shan and the eastern slopes of the Goaligongshan between elevations of 1 138–2 500 m. J. slowinskii has not been recorded on the eastern slopes of the Nushan or the Hengduan Shan, or on the western slope of the Goaligongshan; however, these areas have not been thoroughly surveyed for reptiles. It is unlikely that the species extends beyond the western slopes of the Goaligongshan because of the high altitude of the ridge (above 3 000 m [Chaplin, 2005]). A recent collecting trip (2005) to Dulong Valley, west of the Goaligongshan ridge, only recorded a single agamid species, Pseudocalotes kingdonwardi. ....

Recent fieldwork in southern Tanintharyi revealed the presence of a small Green Crested Lizard in the wet evergreen forest. We generated mtDNA sequence data (ND2) that demonstrates that this population’s nearest relative is Bronchocela rayaensisGrismer et al., 2015 of Pulau Langkawi, northwestern Peninsular Malaysia and Phuket Island. Morphologically the Burmese Bronchocela shares many features with B. rayaensis, which potentially would make this recently described Thai-Malay species a synonym of Bronchocela burmana Blanford, 1878; however, we interpret the genetic and morphological differences to reflect evolutionary divergence and recommend the recognition of both species.

Bronchocela burmana Blanford, 1878
Burmese Green Crested Lizard
BronchocelaburmanaBlanford, 1878, Proceedings of the Asiatic Society of Bengal 1878(6): 141.
Definition
A Bronchocela lizard with a short nuchal crest of six to nine erect triangular crest scales; no middorsal crest of raised scales on trunk. Snout-vent length of adults range from 80 to 94 mm with tail length 240 to 360% of snout-vent length; limbs slender, forelimbs 42–52% of SVL, hindlimbs 86–97% of SVL; digits long and slender with third finger slightly longer than fourth finger, fourth toe distinctly longer that third toe; head medium sized (25–27% of SVL); head with distinct canthal ridge, narrow triangular shaped from dorsal view, length > width ≈ height and approximately 26 % of SVL; moderately large eye (OrbD/HeadL ~26–28%) and about twice diameter of tympanum (continuous with temporal surface).
General description
Detailed metric and scalation features are presented above in the Results section, also Table 2. Bronchocela burmana is a slender green lizard with long tail, usually 2.5–3.5X snout-vent length. In spite of its 80 to 94 mm body length, its slenderness and thin legs give it a delicate appearance and make it immediately recognizable among the other lizards of southern Tanintharyi.
In life, Bronchocela burmana appears uniformly green (Fig. 2). Preservation changed the overall coloration to light olive but highlights a light rufous vertical bar in the temporal area.

Figure 1. Dimorphic secondary sexual ornamentation in different size classes of Salea horsfieldii. Insets a, b, c and d are females of SVL 28.6 mm, 36.2 mm, 57.2 mm and 71.4 mm, respectively, and e, f, g and h are males of SVL 29.08 mm, 40.6 mm, 67.4 mm and 74.7 mm, respectively. The red arrow mark shows the break at the nuchal region in males.
Many agamid lizards are known to show sexual dimorphism in body shape, colour and ornamentation or a combination of these traits. Adult males of Salea horsfieldii have a discontinuous dorsal crest at the nuchal region, which is a sexually dimorphic character. However, there is no information about the age or size at which this dimorphic ornamentation develops and if the species exhibits sexual shape dimorphism (SShD). The authors studied the morphology of S. horsfieldii and found that its ornamentation is an ontogenetically stable character present in all males, including juveniles. Seven morphological characters were measured to determine if they exhibited SShD at adult and juvenile stages. Analysis of covariance was used to identify differences in morphology between sexes. The results show that only adults exhibited SShD, but not juveniles. Adult males had larger head and foot lengths in comparison to females of the same size. Larger head length in adult males is a sexual fitness trait, which increases bite-force during intra-sexual combats. Although the presence of sexually dimorphic ornamentation right from the juvenile stage is rare in agamids, S. horsfieldii is an exception . The role of sexually dimorphic ornamentation at juvenile stages remains unknown and requires further investigation.

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, and three rows of paravertebrals directed dorsally and posteriorly distinguishes the new species from its congeners on Sumatra and Java. Among the new characters defined in this study, counts of subdigital lamellae within the “span of Toe V” proved particularly useful for diagnosing species of Pseudocalotes. Phylogenetic analysis of DNA sequences identified a monophyletic group containing the Sumatran and Javan Pseudocalotes. Based on the phylogeny, we define a P. cybelidermus Group containing P. cybelidermus and P. guttalineatus and a P. tympanistriga Group containing P. tympanistriga, P. rhammanotus, and the new species. Combinations of five morphological characters define each of these two clades. As currently defined, Pseudocalotes is polyphyletic; Javan and Sumatran species are more closely related to other draconines such as Dendragama boulengeri than they are to some mainland species.

Etymology. The new name baliomus is a masculine adjective derived from the Greek adjective balios meaning spotted and Greek noun omos meaning shoulder. The new name refers to the diagnostic white blotches on the shoulder of Pseudocalotes baliomus. Standard English Common Name. Spot-Shouldered False Garden Lizard.

Mountain Dragons of the genus Japalura Gray 1853 have gained increasing systematic attention recently as a result of the availability of new, vouchered collections and a resurgence of interest in Indochinese agamid diversity. This is particularly true for the J. flaviceps Barbour, Dunn 1919 complex from southwest China. However, many species of the complex are still known from few historical specimens only, and little is known about their general biology and conservation status. As one of such understudied members of the complex, Japalura yulongensisManthey, Denzer, Hou, and Wang 2012 was described on the basis of seven historical specimens from the type locality in northwest Yunnan, PR China in 1914. Little was known at the time of the general biology and conservation status of the species, and the species has not been documented in the wild since the original description. Herein, we report the re-discovery of this secretive species based on a series of newly collected specimens from the vicinity of the type locality. We provide the first accounts of body coloration in life and microhabitat preferences, expand upon what is known of the species’ morphological variation and ecology, revise the morphological diagnosis of the species, and offer suggestions on its IUCN conservation status and protection status in China.

Phylogenetic relationships of the agamid lizard genus Phrynocephalus are described in the context of plate tectonics. A near comprehensive taxon sampling reports three data sets: (1) mitochondrial DNA from ND1 to COI (3’ end of ND1, tRNAGln, tRNAIle, tRNAMet, ND2, tRNATrp, tRNAAla, tRNAAsn, tRNACys, tRNATyr, and the 5’ end of COI) with 1761 aligned positional sites (1595 included, 839 informative), (2) nuclear RAG-1 DNA with 2760 aligned positional sites (342 informative), and (3) 25 informative allozyme loci with 213 alleles (107 informative when coded as presence/absence). It is hypothesized that Phrynocephalus phyletic patterns and speciation reflect fault lines of ancient plates now in Asia rejuvenated by the more recent Indian and Arabian plate collisions. Molecular estimates of lineage splits are highly congruent with geologic dates from the literature. A southern origin for the genus in Southwest Asia is resolved in phylogenetic estimates and a northern origin is statistically rejected. On the basis of monophyly and molecular evidence several taxa previously recognized as subspecies are recognized as species: P. hongyuanensis, P. sogdianus, and P. strauchi as “Current Status”; Phrynocephalus bannikovi, Phrynocephalus longicaudatus, Phrynocephalus turcomanus, and Phrynocephalus vindumi are formally “New Status”. Phylogenetic evaluation indicates a soft substrate habitat of sand for the shared ancestor of modern Phrynocephalus. Size diversity maximally overlaps in the Caspian Basin and northwestern Iranian Plateau. The greatest species numbers of six in sympatry and regional allopatry are found in the southern Caspian Basin and southern Helmand Basin, both from numerous phylogenetic lineages in close proximity attributed to tectonic induced events.

Lizards of the genus Calotes are geographically restricted to South Asia, Indo-China and parts of Southeast Asia. The greatest diversity of the genus is from the biodiversity hotspots in South Asia: Western Ghats (Peninsular India), Sri Lanka and Indo-Burma. Here, we present a systematic revision of members of the genus Calotes from Peninsular India using a combination of molecular phylogeny, geographical distribution and morphological characters. We show that Calotes from the Western Ghats is paraphyletic and consists of three major clades, one of which is widely distributed in South and Southeast (SE) Asia, while the others are restricted to Peninsular India. The Peninsular Indian clade is composed of two sister clades: Psammophilus, with a wider distribution and a second clade, composed of two extant species, Calotes rouxii and Calotes ellioti and two new species, all restricted to the Western Ghats region. Based on morphological differences, we retain the generic status of Psammophilus and assign its sister clade to a new genus Monilesaurus gen. nov. and transfer the following species, C. rouxii and C. ellioti, to this new genus. We also provide diagnoses and descriptions for two new species recognized within Monilesaurus gen. nov. In addition, Calotesaurantolabium from the Western Ghats was observed to be deeply divergent and to share a sister-relationship with the clade composed of Calotes, Monilesaurus gen. nov., and Psammophilus. Based on its phylogenetic position and morphological attributes, we assign this species to a new genus Microauris gen. nov. These new discoveries highlight the evolutionary significance of the Western Ghats in housing novel lizard diversity.
