根据形态学和分子生物学证据，描述了采自中国云南南部、越南和泰国的一个新种。该新种过去曾与Zhangixalus smaragdinus（Blyth，1852）混淆。Zhangixalus pachvproctus sp. nov.与Z.在形态学上，雄性的尖吻鲈以突出的气孔为特征，侧腹白色条纹下有大而厚的灰色网状斑点，口鼻部侧面较斜，头较宽，口鼻部较长，腹面距离较大，鼓膜较大，后肢较长。该新种与其它种的背部为绿色的Zhangixalus的区别在于以下特征：（成年雄性SVL：74.2-83.3 mm;成年雌性SVL：102.4 mm）;背部光滑;沿着下颌边缘、身体两侧、四肢外侧和通风口上方有狭窄的白色条纹;前眦、上眼睑和鼓上褶上缺乏棕色带;手指和脚趾之间的蹼完整，前两个手指之间除外;以及内单静脉下声囊。基于16 S rRNA序列的系统发育分析表明，该新种是Z. smaragdinus与两种植物的16 S序列的未校正成对距离相差7.63%。
We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachvproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters: body size larger (SVL of adult males: 74.2-83.3 mm; SVL of adult female: 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.
