Integrated evidence reveals a new subspecies of Amolops Cope, 1865 (Anura, Ranidae) from northeastern Yunnan, China

A new subspecies of <i>Amolops dafangensis</i> Li, Liu, Ke, Cheng, & Wang, 2024, designated as <i>Amolops dafangensis wumengmontis</i> <b>ssp. nov.</b>, is described from Mt. Wumeng, Zhaotong City, northeastern Yunnan, China, based on phylogenetic analysis of the 16S rRNA and <i>CO1</i> genes, as well as morphological examinations. Phylogenetic analysis indicated that specimens from the Wumeng Mountains clustered within <i>Amolops dafangensis</i>, forming two main clades within this species. <i>Amolops dafangensis wumengmontis</i> <b>ssp. nov.</b> demonstrates a close phylogenetic relationship with <i>A. d. dafangensis</i> and is differentiated from the nominal subspecies by specific characteristics: 1) tympanum indistinct; 2) tibiotarsal articulation just reaching anterior corner of the eye; 3) flat and indistinct inner and outer metacarpal tubercles; and 4) webbing formula: I1-1II1-1½III1-2IV2-1V.
