We describe a new species of Theloderma from northwestern Vietnam based on morphological differences and molecular divergence. Theloderma annae sp. nov. is distinguishable from its congeners on the basis of a combination of the following characters: Size small, SVL 27.1-28.5 mm in males, 30.3-32.6 mm in females; head longer than wide; vomerine teeth absent; snout long (SL/SVL 0.16-0.19); spines on upper eyelid absent; tibiotarsal projection absent; dorsal skin smooth; dermal fringes on forearm and tarsus absent; dorsal surface grayish green; and throat and ventral surface of arms and thighs brown with white spots.
我们基于形态差异和分子分歧描述了一种来自越南北部的新角蟾属物种。新物种安娜角蟾（Theloderma annae sp. nov.）可通过以下特征组合与同属其他物种区分开来：体型小，雄性体长（SVL）27.1 - 28.5毫米，雌性30.3 - 32.6毫米；头长大于宽；无犁骨齿；吻长（SL/SVL为0.16 - 0.19）；上眼睑无棘；无胫跗关节突；背部皮肤光滑；前臂和跗部无皮褶；背面灰绿色；喉部以及手臂和大腿腹面棕色且有白色斑点。
