New record and dietary ecology of a poorly-known treefrog, Yu, Hui, Hou, Wu, Rao & Yang, 2019 (Anura, Rhacophoridae) in Vietnam.

Background: The White-lipped Treefrog Yu, Hui, Hou, Wu, Rao & Yang, 2019 was previously confused with (Blyth, 1852). Records of from Yunnan (China), Vietnam and Thailand were recognised as a misidentification and this taxon was subsequently described as a new species, based on morphological and molecular evidence. This species is currently known from southern China, Thailand, Laos and Vietnam.

New records and an updated list of reptiles from Thanh Hoa Province, Vietnam.

Background: Thanh Hoa Province is located in North Central Vietnam and the Province contains a large area of 393,361.33 hectares of natural forest. A complexity of landforms has given this Province a high level of biodiversity potential.

New records of amphibians from Ha Tinh Province, Vietnam.

Background: Since the establishment of the Vu Quang National Park in 2002 in Ha Tinh Province, central Vietnam, several surveys on the amphibian fauna have been undertaken in this protected area. In 2009, Nguyen et al. provided a list of 23 amphibian species from Vu Quang National Park.

Based on morphological and molecular analyses, we herein describe a new species of Achalinus from northern Vietnam. Achalinus quangi sp. nov.

A new species of (Anura, Rhacophoridae) from northwestern Vietnam.

A new species of small tree frog is described from northwestern Vietnam based on morphological differences and molecular divergence. is distinguishable from its congeners and other small rhacophorid species on the basis of a combination of the following characters: size relatively small, SVL 32.2-33.

New record and dietary ecology of a poorly known frog, Wang, Li, Du, Hou & Yu, 2022 (Amphibia, Anura, Ranidae), from Ha Giang Province, Vietnam.

Background: The Hekou Torrent Frog () was recently discovered from southern China and northern Vietnam in 2022. The knowledge about natural history and feeding ecology of this species is virtually lacking.

Two new species of Hemiphyllodactylus (Squamata: Gekkonidae) from Hoa Binh Province, Vietnam.

We describe two new species of the genus Hemiphyllodactylus on the basis of a new collection of geckos from limestone karst forest of Hoa Binh Province, northwestern Vietnam. Hemiphyllodactylus bonkowskii sp. nov.

New records and an updated checklist of snakes from Son La Province, Vietnam.

Background: Son La Province is located in north-western Vietnam and the province contains a large area of 440,000 hectares of natural forest. A wide range of elevations and the complexity of landforms have given this province a great diversity of natural habitats and a high level of biodiversity potential. However, the snake fauna of Son La province is still poorly studied.

Integrative taxonomy reveals three new taxa within the complex (Caudata, Salamandridae) from Vietnam.

The complex from northern Vietnam is reviewed based on morphological comparisons and analysis of the mitochondrial marker NADH dehydrogenase subunit 2 (ND2). Based on molecular divergences, which were revealed to be higher than in other congeners, in concert with morphological differences, two new species and one subspecies are described herein: differs from by 3.2 to 3.

New records of megophryids (Amphibia: Anura: Megophryidae) from Son La Province, Vietnam.

Background: The family Megophryidae is one of the most poorly known groups of amphibians in Son La Province, Vietnam. In the herpetofaunal list of Vietnam in 2009 only two species of megophryids were recorded from this province and recent studies have documented five additional species of Megophryidae from Son La Province.

New Information: Based on recent field work in northern Vietnam, we report six new provincial records of the family Megophryidae from Son La Province, namely , , , , and .
