Redescription of Mugil setosus Gilbert 1892 with comments on the occurrence of Mugil curema Valenciennes 1836 in the Pacific Ocean (Teleostei: Perciformes: Mugilidae)

A redescription of the mugilid fish Mugil setosus, originally described from Clarion Island in Mexico's Revillagigedo Archipelago, reveals key diagnostic traits such as pelvic fin extension beyond the third dorsal-fin spine base, pectoral-fin ray count (ii+13-14), and distinctive dental patterns visible in adults. The study expands M. setosus's known range to include Ecuador and Peru, while also documenting the presence of Mugil curema in the Pacific Ocean for the first time. Researchers analyzed type material alongside newly collected specimens, clarifying taxonomic distinctions between these species. This work contributes to the understanding of mugilid diversity in the eastern Pacific, with implications for biodiversity studies in UNESCO-listed marine sites like the Revillagigedo Archipelago.
