We record Amolops cremnobatus Inger & Kottelat, 1998 for the first time from Thanh Hoa Province, northcentral Vietnam, which also represents the northernmost record of this species. Specimens of A. cremnobatus were found at three limestone karst forest sites within the Pu Hu Nature Reserve at altitudes between 277 and 526 m a.s.l. Adults and larval stages matched the diagnostic morphological characters of the original description of A. cremnobatus, such as small size, tarsal gland present, vomerine teeth present, tympanum distinct, nuptial pads distinctly developed in males, and tadpoles with upper jaw sheath divided and labial teeth row formula 10(5–10)/6(1). Besides natural history notes for both developmental stages and adults, we present an extended larval description based on a tadpole at Gosner (1960) stage 31. The tadpole belongs to the exotrophic, lotic, gastromyzophorus larval type after McDiarmid & Altig (1999) and possesses the typical characteristics of a fast-water stream dweller, i.e., a large abdominal sucker disc, thick tail musculature, and reduced fins. In addition, the first larval staging for the genus Amolops in general is provided in this paper, based on the species A. cremnobatus.
