A description of the tadpole of the Critically Endangered Botsford’s leaf-litter frog (Leptobrachella botsfordi) with comments on the distribution and conservation status of the species

We describe the tadpole of the Botsford's leaf-litter frog Leptobrachella botsfordi, a species endemic to Mount Fansipan in northwest Vietnam, for the first time. Tadpoles of this species were found in steep, fast-flowing streams at elevations between 2500-2600 m asl. We also report a previously unknown locality for this species on Mount Fansipan, which increases the species' known Extent of Occurrence from 8 km2 to 36 km2. Our findings will inform subsequent conservation initiatives for this poorly known and highly threatened species.
