泰国山井疣螈的形态有三个类群。根据分子和形态学数据，我们将其中两个描述为新种，一个来自泰国北方，另一个来自泰国东北部，但是由于缺乏凭证标本和足够的遗传数据，我们无法对剩余的一组进行分类决定。北方种在形态上与所有已知的同类不同，具有橙子至红棕色的斑纹，头部背外侧狭窄而尖锐突出的骨脊，弱分节的脊椎脊，以及长而高的尾巴。东北种的特征是有黄色、橙子或红棕色的斑纹，头上宽而适度突出的背外侧骨脊，光滑的脊椎脊，黑色的四肢和黑色的尾巴，除了边缘。讨论了疣螈属分类学划分的有效性。
Three morphological groups are found in a salamandrid newt Tylototriton shanjing from Thailand. We describe two of them as new species, one from northern and the other from northeastern Thailand, based on molecular and morphological data, however we could not make a taxonomic decision on the remaining one group because of the lack of voucher specimens and sufficient genetic data. The northern species differs morphologically from all known congeners by having the combination of orange to reddish brown markings, narrow and sharply protruding dorsolateral bony ridges on head, weakly segmented vertebral ridge, and long and high tail. The northeastern species is characterized by having the combination of yellow, orange, or reddish brown markings, wide and moderately protruding dorsolateral bony ridges on head, smooth vertebral ridge, black limbs, and black tail except for edges. Validity of taxonomic subdivision of the genus Tylototriton is discussed.
