Abstract

is herein described as a new deciduous species endemic to riparian habitats in Jiuzhaigou, northern Sichuan, China. Phylogenetic analyses based on complete plastome sequences and 322 nuclear loci consistently recover as a distinct and divergent lineage, genetically separated from all morphologically similar species and most closely related to . Species delimitation analyses employing both topology-based (SODA) and substitution-based (bPTP, mPTP) frameworks further corroborate its taxonomic distinctiveness. This discovery highlights previously overlooked species diversity within in the Hengduan Mountains region.

摘要

本文描述了一种新的落叶物种,它是中国四川北部九寨沟河岸栖息地特有的。基于完整叶绿体基因组序列和322个核基因座的系统发育分析一致将其恢复为一个独特且分化的谱系,在基因上与所有形态相似的物种分离,并且与……关系最为密切。采用基于拓扑结构(SODA)和基于替换(bPTP、mPTP)框架的物种界定分析进一步证实了其分类学独特性。这一发现突出了横断山脉地区……内先前被忽视的物种多样性。
