A new species of the crocodile newt genus from Doi Soi Malai located at Mae Tuen Wildlife Sanctuary, Tak Province, northwestern Thailand is described based on molecular and morphological evidence, and named as The new species is the seventh recorded species of the genus reported in Thailand. It differs morphologically from its congeners by a combination of the following morphological characteristics: head longer than wide; snout blunt or truncate; sagittal ridge on head narrow, short and distinct; dorsolateral bony ridges on head pronounced and rough; parotoids distinct; vertebral ridge prominent, wide and not segmented; 14-16 distinct, rounded and isolated rib nodules but posterior nodules connected; tips of fore- and hind limbs overlapping when adpressed along the body. The body background color is black, while the color markings are orange. Molecular analysis indicated that is a distinct lineage and sister to with a 4.1% genetic sequence divergence based on the mitochondrial NADH dehydrogenase subunit 2 gene. The new species is currently restricted to the hill evergreen forests of Doi Soi Malai. The implementation of a strategic plan is recommended to protect both the species and its habitat from anthropogenic activities.
基于分子和形态学证据，对泰国西北部夜功府湄敦野生动物保护区索伊玛莱山发现的鳄螈属新物种进行了描述，并将其命名为 。该新物种是泰国境内记录的鳄螈属第七个物种。它在形态上与其同属物种的区别在于以下形态特征的组合：头长大于宽；吻钝或截形；头部矢状嵴窄、短且明显；头部背外侧骨嵴明显且粗糙；耳后腺明显；脊椎嵴突出、宽阔且无分段；有14 - 16个明显、圆形且孤立的肋骨结节，但后部结节相连；前肢和后肢沿身体贴紧时尖端相互重叠。身体背景颜色为黑色，而色斑为橙色。分子分析表明， 是一个独特的谱系，是 的姐妹种，基于线粒体NADH脱氢酶亚基2基因，其遗传序列差异为4.1%。该新物种目前仅分布于索伊玛莱山的山地常绿森林中。建议实施一项战略计划，以保护该物种及其栖息地免受人为活动的影响。
