We provide a taxonomic update of the herpetofauna of the Ke Go Nature Reserve, Ha Tinh
province, north-central Vietnam, 20 years after the book release “The amphibians and reptiles of
a lowland forest reserve in Vietnam”. In this work, Ziegler (2002) recorded 31 amphibians and
57 reptiles. Since then 30 changes in the generic assignment of species took place, five of six
unnamed identifications could be solved, three unclear identifications clarified, and 12 taxa were
newly described. This review has not only significance for updated names of taxa listed in the
book and follow-up papers, but also for conservation. Reviews and descriptions resulted in taxa
with more restricted distributions, such as, e.g., Gekko reevesii (formerly G. gekko, listed on
CITES Appendix II and in the Red Data Book) and Pelodiscus variegatus (formerly P. sinensis,
listed in the IUCN Red List, and split off taxa on CITES Appendix II). More species meanwhile
are listed as threatened (in total 25), and for some of them, the threat status has increased in the
meantime. In addition to the 88 amphibian and reptile species recorded by Ziegler (2002), three
further records are added herein, resulting in 91 proven species. There is also evidence for the
occurrence of 10 further reptile species, which would increase the herpetofauna list to 101. One
half of these 10 additional reptile species are threatened which would increase the threatened
herpetofauna to 30 species. This highlights the need for improved conservation, both concerning
the official protection status of so far not yet officially listed threatened taxa and IUCN’s One
Plan Approach conservation, covering in situ conservation measures and ex situ conservation
breeding approaches. Representing one of Vietnam’s last remaining lowland forests with a high
biodiversity and conservation value, the Ke Go Nature Reserve highly deserves reinforced
conservation measures.
