<br> A new species of the genus<br> Leptobrachella<br> ,<br> L. darongshanensis<br> sp. nov.<br> , is described from the Darongshan Nature Reserve, Yulin City, Guangxi, China, integrating molecular, morphological, and bioacoustic evidence. The new species can be distinguished from its congeners by a combination of the following characters: (1) medium body size (SVL 24.9–27.7 mm in males; 32.0–35.4 mm in females); (2) dorsal skin rough with small, raised tubercles and ridges; (3) ventral surface creamy white with minute irregular textures and tiny pale brown spots laterally on the belly; (4) flanks bearing irregular black spots; (5) distinct black supratympanic line; (6) rudimentary toe webbing on toes I–IV and absence of lateral dermal fringes on toes; (7) distinct, continuous ventrolateral glandular line; (8) iris bicolored, upper half tangerine, lower half silver with black reticulations, pupil black with tangerine edges; (9) tibiotarsal articulation reaching the posterior margin of the eye when adpressed; (10) advertisement calls with dominant frequencies of 6.1–6.7 kHz at 20.0 °C. Phylogenetic analyses based on the mitochondrial 16S rRNA gene indicate that<br> L. darongshanensis<br> sp. nov.<br> and<br> L. shiwandashanensis<br> are sister taxa. The new species is currently known only from montane evergreen forests at elevations between 800 and 1,200 m within the Darongshan Nature Reserve, where it is sympatric with<br> L. yunkaiensis<br> .<br>
