Abstract
Herein, we provided a morphological description combined with a phylogenetic analysis of the northernmost Thai Tylototriton population, which was found in Doi Pha Hom Pok National Park (DPHPNP), Chiang Mai Province, northern Thailand. Three adult males were collected from a small breeding pond during our survey in July 2020. Based on molecular (two specimens) and morphological (three specimens) evidence, all three specimens from NP were identified as Tylototriton verrucosus Anderson, 1871, and were characterized by having a blackish background, orange to light orange-brown color markings, segmented vertebral ridge, prominent rib nodules ranging from 13–15 warts, and a rough skin with granules. Hence, this second record of T. verrucosus populations in Thailand confirms a range extension of this species in northern Indochina. Additionally, the morphological variation and conservation status are discussed for the populations from Thailand.
