A redescription and range extension of Trimeresurus caudornatus Chen, Ding, Vogel & Shi, 2020 (Serpentes: Viperidae).

The pitviper species Trimeresurus caudornatus was recently described based on only two specimens from Nabang Town, Yingjiang County, Yunnan Province, China. Here, we provide additional data on this species based on a re-examination of 19 preserved specimens, 16 specimens reported in earlier literature sources, and additional photo-documented records from northern Myanmar (Burma) and adjacent China. All new specimens were previously identified as Trimeresurus albolabris sensu lato or Trimeresurus septentrionalis sensu lato.

Another new species of Cyrtodactylus Gray, 1927 (Squamata: Gekkonidae) of the angularis group from the karstic landscape of Phong Nha-Ke Bang National Park, central Vietnam.

The Phong Nha-Ke Bang (PNKB National Park in the Central Highlands of Vietnam is a bastion for the protection and conservation of Vietnam's natural heritage. Thus, the discovery of yet another new species of Cyrtodactylus, C. hangvaensis sp.

(Rodentia, Platacanthomyidae): new species of the genus from northern Vietnam with notes on conservation status and distribution.

Background: The paper presents novel findings of little-known species of rodents, the blind tree mice in Son La Province, Vietnam, with the first morphological and genetic characterisation and taxonomical description of the new species, . The study also summarises all the data available on this genus species distribution, museum collections and notes on its taxonomy, which are important to establish the proper conservation status of the species. An exhaustive map of the findings is provided, along with a refined taxonomic key for all six currently morphologically characterised species of the genus.

TWO NEW CERATOMYXA SPECIES (MYXOSPOREA: CERATOMYXIDAE) INFECTING THE GALL BLADDER OF MARINE FISHES FROM THE SOUTH-CENTRAL COAST OF VIETNAM.

Myxospores discovered floating free in the bile of marine fishes from the south-central coast of Vietnam were identified using morphological and molecular methods, leading to the description of 2 new species. Ceratomyxa chauvanminhi n. sp.

New Data on (, ) from Central Vietnam with Description of Two New Species and Creation of a New Combination Based on Morphological and Phylogenetic Evidence.

Two new species of ( and ) discovered during an investigation of the mycobiota of Central Vietnam (Kon Chu Rang Nature Reserve; Ta Dung National Park; Bidoup-Nui Ba National Park; Kon Ka Kinh National Park) are described on the basis of molecular and morphological data. Illustrated descriptions of their macro- and microscopic features and discussion on similar taxa are given. Additionally, eight species which were recorded for the first time in Vietnam are listed and illustrated here.

Another new species of Dibamus Dumril & Bibron, 1839 (Squamata: Dibamidae) from Nui Chua National Park, Ninh Thuan Province, Vietnam.

A new species of dibamid lizard, Dibamus deimontis sp. nov., is described based on eight specimens collected from the highlands of Nui Chua Mountain within Nui Chua National Park, Ninh Thuan Province, southern Vietnam.

A new species of Cyrtodactylus Gray, 1827 (Squamata: Gekkonidae) from the Thai-Malay Peninsula and the independent evolution of cave ecomorphology on opposite sides of the Gulf of Thailand.

An integrative taxonomic analysis recovers a distinctive new species of the gekkonid genus Cyrtodactylus Gray, 1827 from Satun Province in extreme southern Thailand as the sister species to the Cyrtodactylus intermedius group of southern Indochina, approximately 600 km to the northeast across the Gulf of Thailand. Based on 1449 base pairs of the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNAs, the new species, C. disjunctus sp.

A new species of the genus Dibamus Dumril & Bibron, 1839 (Squamata: Dibamidae) from the driest and hottest place of Vietnam.

A new species of the genus Dibamus Dumril & Bibron, 1839 is described based on seven specimens collected from Nui Chua National Park, Ninh Thuan Province, southern Vietnam, the hottest and driest place of the country. Dibamus tropcentr sp. nov.

A new species of the genus Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) from a lowland monsoon forest in Southern Vietnam.

An integrative taxonomic analysis delimits and diagnoses the new species Hemiphyllodactylus cattien sp. nov. from Cat Tien National Park, Dong Nai Province, southern Vietnam-the eighth species of Hemiphyllodactylus to be described from Vietnam.

New Species of Subgenera and (Agaricales, Basidiomycota) from Central Vietnam.

Four new species of from Kon Chu Rang Nature Reserve and Ta Dung National Park were discovered during an investigation of the diversity of the mycobiota of Central Vietnam and are described here on the base of the molecular and morphological data. Phylogenetic analysis was based on nrITS1-5.8S-ITS2, nrLSU and regions.
