This study represents the first report on the amphibians and reptiles of Mount Korbu, the highest peak in the Titiwangsa Range (2182 m a.s.l.) and the second highest peak in Peninsular Malaysia. The Titiwangsa Range is the longest and most contiguous mountain range in Peninsular Malaysia, but only three upland localities have been extensively sampled and published on, indicating the urgent need for fieldwork to new localities along this range. We documented 18 species of amphibians from the families Bufonidae, Dicroglossidae, Megophryidae, Microhylidae, Ranidae, and Rhacophoridae and 16 species of reptiles from the families Agamidae, Gekkonidae, Scincidae, Colubridae, Pareidae, Viperidae, Testudinidae, and Trionychidae. This study also records significant range extensions for four species and provides the first collated checklist on the herpetofauna of the Titiwangsa Range.
