Brachytarsophrys wui sp. nov. can be distinguished from its congeners by the following combination of morphological characters: (1) medium body size (SVL 88.1 – 93.2 mm in five adult males and 108.7 – 111.2 mm in two adult females); (2) head very large, wider than long, and nearly one-half as broad as the SVL; (3) tympanum hidden; (4) pupils black, iris brownish red; (5) upper eyelid with tubercles, one of which is enlarged and becoming a prominent, bluntly conical horn; (6) dorsal skin slightly rough with irregularly shaped dark blotches and stripes; (7) belly, chest, and limbs smooth with irregular off-white spots; (8) chin, ventral surface of throat rough with dark brown, irregularly shaped markings, two large longitudinal black-brown stripes on lateral throat; (9) single subgular vocal sac openings slit-like, located posterolateral on floor of mouth in male; (10) indistinct brown nuptial pad on the dorsal surface of the first and second fingers base, with dense, tiny, black nuptial spines in adult male during breeding season; (11) forelimb short and thick, webbing absent, One third as broad as distal toe phalanx; (12) relative length of fingers I <II <IV <III; (13) toes about I (1 ½) - (2) II (1 ½) - (3) III (2 ½) - (4) IV (4) - (2) V webbed in male; (14) tadpoles with a transverse white stripe, white speckles on posterior ventral surface, and two longitudinal white stripes along the sides of body; (15) oral disk with lips expanded vertically forming dorsally oriented funnel.	en	Lyu, Jing-Cai, Zhou, Sheng-Lun, Zhang, Ting-Bi, Fang, Yang, Ran, Si-Yu, Dai, Liang-Liang, Jiang, Xuan-Kong, Long, Han-Wu, Yuan, Guo (2026): Morphological and molecular data reveal one new species of the genus Brachytarsophrys Tian & Hu, 1983 (Anura, Megophryidae) from Guizhou, China.

7191F85362A6519097FCCAFDBA47261A.taxon	etymology	Etymology. The specific epithet ‘‘ wui ’’ is in honor of late professor and zoologist Lyu Wu (1915 – 1983), vice president (1969 – 1975) of Guizhou Academy of Sciences (Guizhou Province, China), in recognition of his efforts on biodiversity surveys and research in Guizhou Province in the 1960 s and 70 s. For the common name, we recommend “ Wu’s Short-Legged Toad ” (English) and “ Wu Shi Duan Tui Chan ” (伍氏短腿蟾) (Chinese).	en	Lyu, Jing-Cai, Zhou, Sheng-Lun, Zhang, Ting-Bi, Fang, Yang, Ran, Si-Yu, Dai, Liang-Liang, Jiang, Xuan-Kong, Long, Han-Wu, Yuan, Guo (2026): Morphological and molecular data reveal one new species of the genus Brachytarsophrys Tian & Hu, 1983 (Anura, Megophryidae) from Guizhou, China.
