First confirmed country record of the globally threatened Uperodon assamensis (Das, Sengupta, Ahmed & Dutta, 2004), Assamese Balloon Frog (Amphibia, Anura, Microhylidae), from Bangladesh, with an updated global rang
We report a new country record of Uperodon assamensis (Das, Sengupta, Ahmed & Dutta, 2004) from Bangladesh. The specimen was identified by its distinctive yellowish dorsal vertebral stripe, absence of tympanum and vomerine teeth, rounded choanae, oval tongue, and supratympanic fold. Among the type specimens, snout–vent length, head width, head depth, tibia length, and axillary‑groin distance reveal substantial variability. In contrast, eye diameter, internarial distance, eye nostril distance, and eye‑to‑snout distance show less variability. We also mapped the current global distribution in India, Nepal, and Bangladesh.
