A new leaf litter toad, Leptobrachella yongshunensis sp. nov. , is described on the basis of morphological, acoustic, and molecular data in this study. The species was distributed Xiaoxi National Nature Reserve, Yongshun County, Xiangxi Tujia Miao Autonomous Prefecture, Hunan Province, China. Phylogenetical analysis revealed that sister L. wulingensis (p-distance 0.019 16s rRNA gene, p-distance 0.073 COI gene). duration advertisement call 194.2 ± 6.7 ms, mean dominant frequency first note 3.885 0.066 kHz, second 3.914 0.052 kHz. can be distinguished from its congers by following morphological characters: snout-vent length (SVL) 27.2–28.9 males, SVL 26.2–31.6 females; black spots flanks; toes webbing rudimentarily; narrow fringes toes; creamy white ventral body with indistinct speckling at margins; dorsal sparse large warts, dense little wart grains, longitudinal ridges; head width greater than length; tibiotarsal articulation reaching to anterior edge eye; brick-red color surface; upper parts iris bright coppery life. We still supplemented gene for further research. discovery not only enhances diversity Wuling Mountains, but also suggests hidden area.

Morphological and molecular evidence for a new species of the genus Leptobrachella (Anura, Megophryidae) from Gaoligong Mountain Range, Yunnan, China

The Gaoligong Mountain Range in Yunnan Province, China, is characterized by its large variation elevation and topography, together with wide latitudinal range, resulting extremely high levels of biodiversity. Studies show that the amphibian diversity largely underestimated, especially south. During herpetological surveys 2023 2024, three specimens Leptobrachella were collected from mountain at Tongbiguan Provincial Nature Reserve. Subsequent morphological comparisons a phylogenetic reconstruction revealed these belonged to previously unknown morphologically distinct lineage , which we formally describe. Our discovery brings number species genus 108, 44 occur seven on Range. This result confirms underestimated Range, Reserve, where multiple sympatric congeneric occur, including four five putative new Xenophrys Polypedates . These findings also highlight need for future research investigate mechanisms syntopic coexistence.
