摘要	A new species of the genus Yunnanilus, designated Yunnanilus triangulus sp. nov., is described from the Nanpan River in Yunnan Province, southwestern China. Nuptial males of this species are distinguished by the presence of tubercles on the caudal peduncle during the reproductive period, a feature not observed in other members of the genus. The new species is further characterized by the following unique combination of morphological characters: body scaled, smaller eyes than interorbital width, nine inner gill rakers on first gill arch, lateral head length 27.1%-30.9% SL, head width 14.3%-17.2% SL, eye diameter 19.6%-23.8% of lateral head length, and caudal peduncle depth 94.0%-130.6% of its length. Morphological and molecular evidence support the validity of this species, despite its geographic proximity to Y. polylepis. These findings underscore the ecological specialization that exists within the genus Yunnanilus and highlight the urgent need for species-specific conservation strategies, given their restricted distributions and dependence on specific habitats.
