摘要：A new species of the genus Tylototriton is described from eastern Himalaya based on molecular and morphological comparisons. The new species is diagnosable from the closely-related species by having light brown colouration in dorsal region in life, flat and blunt snout, greatly separated dorsolateral bony ridges on head and straightthick tailfin. In addition to head morphology, the new species is also morphologically distinguishable from its closelyrelated species Tylototriton shanorum by having 16 dorsal warts and average smaller Snout Vent Length（SVL）.
