A new species of the genus Boulenophrys (Anura, Megophryidae) is described from Mount Lushan, Jiangxi Province, China, long considered to be Boulenophrys boettgeri. Phylogenetic analyses based on mitochondrial COI and 16S rRNA genes show that the new species forms a sister clade to B. jinggangensis, with an uncorrected COI p-distance of 3.7%, confirming its status as a distinct species. Morphologically, it differs from all known congeners by a unique combination of characters, and from its closest relative B. jinggangensis by having the following traits: (1) larger adult body size (adult males SVL 42.7–44.7 mm; adult females 46.0–50.3 mm); (2) heels not meeting when hindlimbs are flexed at right angles to the body axis; (3) smaller horn-like tubercle on the upper eyelid; and (4) relative finger lengths (I < II < IV < III). Acoustically, the new species differs markedly from B. jinggangensis in nearly all parameters of its advertisement calls. This discovery increases the known species diversity of Boulenophrys in Jiangxi Province and provides baseline data for further biodiversity conservation efforts in the Mount Lushan region.

A new species of the genus Boulenophrys (Anura, Megophryidae), Boulenophrys nebulosa sp. nov. , is described from Mt. Lushan, Jiangxi Province, China. Phylogenetic analyses based on mitochondrial COI and 16S rRNA genes show that the new species forms a sister lineage to B. mufumontana . Morphologically, B. nebulosa sp. nov. differs from all known congeners by a unique combination of characters and from its closest relative, B. mufumontana , by the following combination of characters: (1) relative finger lengths I < II < IV < III; (2) indistinct subarticular tubercle at the base of each finger; (3) larger male body size (SVL 31.8–32.3 mm); (4) heels just meeting when hindlimbs are folded; (5) tibiotarsal articulation reaching the center of the eye when the leg is stretched forward; and (6) vomerine teeth present. This study expands the known distribution of Boulenophrys in Jiangxi and provides baseline data for biodiversity conservation efforts in Mt. Lushan.

Animal migration is an adaptive strategy for exploiting spatio-temporal fluctuations in resource availability, where site fidelity provides advantages unde
