Abstract
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.
