A new parrotfish (Scaridae) from Brazil, and revalidation of Sparisoma amplum (Ranzani, 1842), Sparisoma frondosum (Agassiz, 1831), Sparisoma axillare (Steindachner, 1878) and Scarus trispinosus Valenciennes, 1840
Abstract:A total of 19 species of parrotfishes (Scaridae) have been recorded from the southwestern Atlantic. Nine of these species records (Sparisoma aurofrenatum, Sparisoma chrysopterum, Sparisoma rubripinne, Sparisoma viride, Scarus coelestinus, Scarus coeruleus, Scarus iserti, Scarus taeniopterus and Scarus vetula) are based on misidentifications, and these species do not occur in the southwestern Atlantic. Of the remaining 10 species, Scarus zelindae is described as a new species, and Sparisoma frondosum (Agassiz, 1831), Sparisoma amplum (Ranzani, 1842), Sparisoma axillare (Steindachner, 1878) and Scarus trispinosus Valenciennes, 1840 are revalidated as southwestern Atlantic species. Cryptotomus roseus Cope, 1871, Nicholsina usta (Valenciennes, 1840), Sparisoma atomarium (Poey, 1861), Sparisoma radians (Valenciennes, 1840) and Scarus guacamaia Cuvier, 1829 are confirmed as Brazilian records. This study shows that at least five parrotfishes add to the Brazilian-endemic reef fishes isolated from the Caribbean by the freshwater plume off the Amazon and Orinoco river mouths.
