The Himalayas represent a renowned biodiversity hotspot and an important biogeographic realm that has influenced origin and diversification of multiple taxa. A recent herpetological investigation of the eastern Himalayas of the Indian state of Arunachal Pradesh led to the discovery of a unique lineage of ablepharine skink, which is herein described as a new genus along with a new species. The findings are based an integrated taxonomic approach incorporating data from external morphology, microCT scans of the skull and molecular data. The molecular phylogeny of ablepharine skinks is also presented that suggests taxonomic amendments. Discovery of this unique lineage of skinks further highlights the biogeographic importance of the eastern Himalayas as a source for origin of several relic biota.

A new species of bent-toed geckos of the genus Cyrtodactylus is described from western Arunachal Pradesh. The new species is a member of the Indo-Burma clade and is embedded within the {\textquoteleft}peguensis" group, a relationship deduced contingent on a partial fragment of mitochondrial NADH subunit 2 gene. Cyrtodactylus kamengensis sp. nov. is morphologically similar to C. himalayicus from which it differs in bearing a distinct ventrolateral fold and 6-8 basal lamellae on digit IV of pes. Genetically, the new species is sister to the Indian lineage of the {\textquoteleft}peguensis" group containing C. bhupathyi and C. gubernatoris. The Indian lineage of the {\textquoteleft}peguen-sis" group diverged from its Burmese relatives during the mid-Oligocene likely followed by the beginning of the Himalayan uplift, highlighting the role of the Himalayas in the diversification of biota.

We here describe a new species of bent-toed geckos from the northeastern Indian state of Arunachal Pradesh, which is widespread across the Dafla and Mishmi hills, occurring at elevations ranging from 179 m to 1400 m. The new species is recovered as sister to the Cyrtodactylus khasiensis clade based on a molecular phylogeny inferred from mitochondrial NADH-ubiquinone oxidoreductase, subunit 2 gene. Intraspecific uncorrected pairwise sequence divergence (p-distance) for the new species was found to be between 0 and 5\%, whereas the interspecific divergence from the closely-related congeners was between 19 and 30\%. The new species can be differentiated from members of the C. khasiensis clade using a suite of morphological characters: moderate body size (SVL 64.9{\textendash}81.7); 8{\textendash}11 supralabials; 8{\textendash}10 infralabials; 24{\textendash}26 bluntly conical, feebly keeled dorsal tubercles; 50{\textendash}60 paravertebral tubercles; ~38 ventral scales between ventrolateral folds; no precloacal groves; 6{\textendash}10 precloacofemoral pores in a continuous series; 10{\textendash}16 distal subdigital lamellae on IV of pes; subcaudal scalation of original tail without enlarged plates. This is the fourth reptile species described from Arunachal Pradesh from the expedition led by the team, and this further highlights the need for further herpetological investigations into the region.

The montane agamid species Pseudocalotes austeniana has had a complicated taxonomic history, as the species was initially described as a member of the genus Salea Gray, 1845. Later, the species was placed in a monotypic genus Mictopholis Smith, 1935, which was erected only to include this species; however, the species was later on transferred to the genus Pseudocalotes Fitzinger, 1843, owing to the morphological similarities, and lack of strong characters to diagnose the genus Mictopholis. Nonetheless, its precise phylogenetic and systematic position has remained unresolved due to the lack of molecular sequence data. During a herpetological expedition to Arunachal Pradesh, specimens of P. austeniana were collected from the hills near the type locality. The mitochondrial 16S rRNA, ND2 and ND4, and the nuclear RAG1 regions were subjected to molecular phylogenetics. Maximum Likelihood and Bayesian Inference gene trees revealed that P. austeniana is a member of the subfamily Draconinae. The analyses showed that the genus Pseudocalotes is polyphyletic, and P. austeniana was embedded within the genus Japalura Gray, 1853 sensu stricto. We here, thus, propose to transfer the species P. austeniana to the genus Japlaura, as Japalura austeniana comb. nov. Biogeographic and evolutionary significance of the findings are discussed.

A new species of snail-eating snakes of the genus Pareas Wagler, 1830 is described from the eastern Himalayas. The species Pareas kaduri sp. nov. differs from all known species of the genus in bearing the following suite of characters: SVL 455-550 mm, TaL/TL 0.184-0.207, brown dorsum with black transverse bands throughout the body, 15 dorsal scale rows throughout the body and mid-dorsal vertebral scale rows enlarged, 8 rows keeled in males, loreal not touching orbit, ventrals 160-183, subcaudals 65-70 in males, 52 in one female specimen, hemipenis short, unilobed and 6-7 maxillary teeth. Molecular data for mitochondrial 16S rRNA and cytochrome b genes further attest the distinctness of the new species, which was recovered as a member of the Pareas hamptoni clade. Our work brings the total number of species recognized within the genus Pareas to 20.

Calotes versicolor Daudin, 1802 is one of the most widespread agamid lizard species which was described without a locality. The type specimen of the species has long been considered lost; however most workers considered Pondicherry as the type locality for the species. Studies by Zug et al. 2006 confirmed that C. versicolor is a complex of multiple species which necessitates fixing type locality and specimen for the species in order to resolve the systematics of the species complex. An adult male from Pondicherry was collected and is here designated as the neotype. A re-description of the species is provided along with notes on systematics of the species.
