There are also 23 species whose presence in Iranian waters needs confirmation by specimens. The most diverse order is the Cypriniformes with 120 confirmed species (59.4%) followed by Perciformes with 28 species (13.9%), Cy- prinodontiformes (10 species, 5.0%), Clupeiformes (9 species, 4.5%), Salmoniformes (7 spe- cies, 3.5%), Mugiliformes and Siluriformes each with 6 species (3.0%), Acipenseriformes (5 species, 2.5%), Gasterosteiformes (3 species, 1.5%), and 8 other orders each with one species (0.5%). New species are still being discovered, 7 described in 2009, while others are being resurrected from synonymy, newly recorded from Iran, or exotic species newly established. Some taxonomic problems remain and are commented on briefly. Thirty-nine endemic species (19.3%) in 6 families and 23 exotic species (11.4%) in 8 families are listed here. The mosqui- tofish, Gambusia holbrooki Girard, 1859 is the most widespread exotic species.
