本文根据形态学和分子生物学证据描述了采自越南西北部和泰国北方的疣螈属一新种。角头疣螈（Tylotototriton anguliceps sp. nov.）与其他同类的区别在于其头部、身体和尾部的亮至暗的橙子斑纹、头部的突出背侧和背外侧脊（脊）、上颌骨和翼骨之间的骨骼连接以及独特的线粒体和核DNA序列。我们的分子数据表明，新物种是嵌套在分支包括T。uyenoi，T. shanjing，T. verrucosus和T.杨吉该新物种预计未来将在中南半岛地区的其他国家如中国南部、缅甸西部和老挝北方记录到。
We describe a new species of Tylototriton from northwestern Vietnam and northern Thailand based on morphological and molecular evidence. Tylototriton anguliceps sp. nov. is distinguishable from all the other congeners by the bright to dark orange markings on the head, body, and tail, prominent dorsal and dorsolateral ridges (crests) on the head, skeletal connection between maxillary and pterygoid, and unique mitochondrial and nuclear DNA sequences. Our molecular data show that the new species is nested within the clade comprising T. uyenoi, T. shanjing, T. verrucosus, and T. yangi. The new species is expected to be recorded from other countries in the Indochina region such as southern China, western Myanmar and northern Laos in the future.
