The Snakes of Laos by Patrick David, Alexandre Teynie & Gernot Vogel. 
 
This publication covers 125 species of snakes known to inhabit Laos (as of 2023). It is largely based on literature, but also encompases the results of numerous field trips in Laos, and studies conducted over years of specimens deposited in numerous world-wide collections.  This has resulted in a wealth of new and unpublished data for the snakes of this still poorly known country.  Each species and subspecies account includes the systematics, nomenclature, extensive discussion about the synonyms and the taxonomic history, detailed morphological descriptions, distribution, both general and within the borders of Laos, biology, legal protection, snakebites if necessary, and relevant bibliographical references.  Distribution maps are presented for every species. An extensive introduction covers all aspects of the geography, climate, ecoregions, habitats, and history of herpetology in Laos. A key to Laotian families and species is provided. An extensive bibliography concludes the volume before an index. There is hardly any recent regional work about snakes with such an amount of information.
