Updated Checklist of the Herpetofauna of Brunei Darussalam

Abstract

We provide an updated checklist of the herpetofauna of Brunei Darussalam based on literature data, citizen science records, field surveys, and opportunistic observations. Forty-four species are added to the checklist of the country, bringing the total number of herpetofauna in Brunei to 248 species (90 amphibians and 158 reptiles). The new records include the enigmatic Glyphoglossus flavus, G. smithi, Rhacophorus borneensis, Lanthanotus borneensis, four species of Calamaria, Gonyosoma margaritatum and a new species of rock gecko, Cnemaspis gituen. The additional species improve our knowledge on the herpetofaunal diversity of Brunei and their range distribution in this region. Our study also reflects the need for further field and taxonomic work as well as citizen-science involvement, to uncover the hidden herpetofaunal diversity of Brunei. With the expanding threat of extinctions, enhanced knowledge on Borneo’s biodiversity and their population trends will provide essential baseline information to support evidence-based conservation actions.
