(Squamata: Viperidae), the Second Known Species of Lance-Headed Pit Viper from Thailand}, volume={20}, url={https://li01.tci-thaijo.org/index.php/tnh/article/view/208081}, abstractNote={<p><em>Protobothrops kelomohy</em> <strong>sp. nov.</strong> is described from dry evergreen forest in Chiang Mai Province, northern Thailand, based on morphology and a molecular phylogeny. It differs from congeners by the following combination of characters: 1) relatively large body size (total length up to 1,310 mm); 2) dorsal scale rows 23–23–17, all keeled; 3) ventral scales 231–234; 4) subcaudal scales 80–84, paired; 5) supralabials 8–9; 6) infralabials 12–13; 7) typical lance-pattern on upper head surface; 8) three bold vertical facial stripes; and 9) dorsal and tail brown, each scale with dark reddish-brown transverse blotches, edged in black, somewhat fused together as a median zigzag line on dorsum, a row of large ventrolateral blotches on each side, each darker marking edged by a narrow yellow line. The new discovery and other recent findings suggest that further herpetological research is required in the montane forest of northern Thailand and adjacent Myanmar and Laos. Data on the natural history of the new species and an updated key to the species of <em>Protobothrops</em> are provided. This is the second species of Lance-headed Pit Viper recorded from Thailand after <em>P. mucrosquamatus</em>.</p>}, number={1}, journal={Tropical Natural History}, author={Sumontha, Montri and Vasaruchapong, Taksa and Chomngam, Niruth and Suntrarachun, Sunutcha and Pawangkhanant, Parinya and Sompan, Weerasak and Smits, Ton and Kunya, Kirati and Chanhome, Lawan}, year={2020}, month={Mar.}, pages={43–59} }
