|Abstract||From the 8(th) to the 11(th) April 2007 at Reunion Island (Indian Ocean) some fish were collected at sea surface after the eruption of the Piton de la Fournaise. Among these are two specimens of Symphysanodon (Perciformes: Symphysanodontidae). This family was recently reviewed (Anderson and Springer, 2005). Ten species have been described: three from the Atlantic Ocean S. berryi Anderson, 1970; S. octoactinus Anderson, 1970 and S. mona Anderson & Springer, 2005; four from the Pacific Ocean S. typus Bleeker, 1878; S. katayamai Anderson, 1970; S. maunaloae Anderson, 1970 and S. parini Anderson & Springer 2005; three from the Indian Ocean S. andersoni Kotthaus, 1974 from the entrance of the Gulf of Aden, S. rhax Anderson & Springer, 2005 from the Maldives Islands and S. disii Khalaf & Krupp, 2008 from Red Sea. An undescribed species with a lower number of gillrakers on the first arch was found partially digested in the stomach content of a coelacanth from the Comoros (McCosker, 1979). The two specimens found at Reunion Island are distinguishable from all Indopacific species of Symphysanodon by the following combination of characters: 19 caudal fin rays; 15 pectoral fin rays; 48-50 tubed lateral line scales; a total of 34-36 gillrakers on the first gill arch; a long depressed anal fin (33-38% SL); a long pectoral fin (length 30% SL) and comparatively large big eyes (10-11 % SL). These specimens are described as a new species named Symphysanodon pitondelafournaisei. A key to Indopacific species is given.|
