Geographic structure of genetic variation in the Parachute Gecko Ptychozoon lionotum Annandale, 1905 across Indochina and Sundaland with descriptions of three new species.

An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages.

Population demography of Oldham's leaf turtle () in protected and disturbed habitats in Thailand.

Background: Freshwater turtle populations are vulnerable to a range of human activities because of particular life history attributes, and anthropogenic impacts can cause shifts in demographic traits, including survival, density and population structure. Asian freshwater turtles have undergone dramatic population declines in recent decades principally because of collection for food, pet, and traditional medicine markets. Despite this, few studies have been conducted on the population demography of these turtles, thereby limiting our understanding of population trends and the development of conservation actions.

A new caruncle-bearing fanged frog (, Dicroglossidae) from Laos and Thailand.

A new species of the dicroglossid frog genus is described from recent and historical museum specimens collected in central and southern Laos and northeastern Thailand. has males that bear a caruncle on top of the head, and most closely resembles from adjacent southern Vietnam and eastern Cambodia. However, the new species is readily distinguished from , and all other caruncle-bearing species of in mainland Southeast Asia, by its adult and larval morphology, mitochondrial DNA, and advertisement call.

A new Limnonectes (Anura: Dicroglossidae) from southern Laos.

A new species of "fanged frog" in the genus Limnonectes resembling L. kohchangae (Smith, 1922) from southeastern Thailand and southwestern Cambodia is described from upper elevations of the Bolaven Plateau, southern Laos. However, the new species, L.

A new Philautus (Anura: Rhacophoridae) from northern Laos allied to P. abditus Inger, Orlov & Darevsky, 1999.

The small rhacophorid frog Philautus abditus is geographically restricted to central Vietnam and adjacent Cambodia. Our fieldwork in northern Laos resulted in the discovery of a Philautus species that very closely resembles P. abditus, but is at least 330 km from the nearest known locality of that species.
