We describe Gehyra wongchan sp. nov. from Tham Khao Chan (Khao Chan Cave), Tha Luang District, and Wat Khao Wong, Kok Samrong District, in Lopburi Province, central Thailand. The new species differs from all currently recognized Gehyra by the following combination of morphological characters and dorsal color pattern: maximal known snout–vent length...

This study focuses on comprehensive characterization of the venom proteome of the beaked sea snake (Hydrophis schistosus) from Songkhla Lake, Thailand. H. schistosus can be considered as the deadliest sea snake commonly found in the Pacific and Indian oceans. Their envenomation causes muscular paralysis and rhabdomyolysis. To develop effective trea...

A new short-horned lizard species of the genus Acanthosaura from southern Thailand, is described herein.

In Thailand, five species of Acanthosaura have been recorded so far, including Acanthosaura armata from the southern region, A. cardamomensis from the eastern region, A. crucigera from the western region, A. lepidogaster from the northern region and A. phuketensis from the Phuket Island and south-western region. However, comprehensive studies of di...

Protobothrops kelomohy sp. nov. is described from dry evergreen forest in Chiang Mai Province, northern Thailand, based on morphology and a molecular phylogeny.

The legless skink Isopachys anguinoides (Squamata: Scincidae), endemic to peninsular Thailand, has been assessed as Least Concern because of its wide ecological tolerance and its presence in a national park. It lives in dense rainforest as well as in plantations and on beaches. Citation: Sumontha, M., Cota, M., Ineich, I. & Pauwels, O.S.G. 2018. Is...

Khorat Supple Skink Lygosoma koratense (Squamata: Scincidae), endemic to Thailand (Nakhon Ratchasima and Saraburi provinces) has been assessed as Least Concern because it is not under any major threat and is unlikely to be experiencing significant population declines due to its adaptability.

PCR-RFLP based technique for identification of sea snakes in Thai waters was achieved by developing species-specific markers. To distinguish between sea snake species, the PCR products of cytochrome b (Cyt b), 12S and 16S rRNA were sequenced and cut with different restriction endonuclease, Alu I and Hinf I. Each enzyme generated different - sized f...

Snakes swallow their prey whole and their prey size is thus limited by their maximal gape, with exceptions being three scolecophidian snakes known to be able to decapitate termites, and two mangrove-dwelling snakes (Squamata: Homalopsidae: Gerarda prevostiana and Fordonia leucobalia) that are able to remove and ingest pieces from crabs. Here we pre...
