A new species of the genus Mittleman, 1950 is described from northern Vietnam based on morphological and molecular evidence. is characterized by a combination of the following characters: size medium (SVL up to 59.4 mm); primary temporals 2; external ear opening without lobules; loreals two; supralabials seven or eight; infralabials six or seven; nuchals in three pairs; midbody scales in 28 rows; dorsal scales smooth, in six rows across the back; paravertebral scales 60-67, not widened; ventral scales in 60-70 rows; ten smooth lamellae beneath finger IV and 13-15 beneath toe IV; toes not reaching to fingers when limbs adpressed along body; dorsal surface of body and tail bronze brown with few black spots, a dark stripe running from nostril to eye and extending from posterior corner of eye along upper part of flank to the middle of the tail. In the phylogenetic analyses, the new species is recovered as an independent lineage with no clear sister taxon and at least 17.3% genetic divergence from other species in the genus based on a fragment of the mitochondrial COI gene.
基于形态学和分子证据，在越南北部描述了米特尔曼属（Mittleman，1950）的一个新物种。其特征如下：体型中等（体长可达59.4毫米）；初级颞鳞2枚；外耳孔无叶状结构；鼻间鳞2枚；上唇鳞7或8枚；下唇鳞6或7枚；项鳞3对；中段体鳞28行；背部鳞片光滑，背部有6行；椎旁鳞片60 - 67枚，不增宽；腹鳞60 - 70行；第四指下有10枚光滑的栉缘，第四趾下有13 - 15枚；四肢沿身体贴伏时，趾不达到指；身体和尾部背面铜褐色，有少量黑点，一条深色条纹从鼻孔延伸至眼睛，并从眼后角沿体侧上部延伸至尾中部。在系统发育分析中，基于线粒体COI基因片段，该新物种被确认为一个独立的谱系，没有明确的姐妹分类单元，与该属其他物种至少有17.3%的遗传差异。
