A new species of slopefish, Symphysanodon disii n. sp., is described on the basis of one specimen, 165 mm standard length (SL), collected off the coast of Aqaba, Jordan, Gulf of Aqaba, Red Sea. It is characterised by the following combination of characters: 10 dorsal soft rays, 7 anal soft rays, 50 tubed scales in the lateral line and 12 + 25 = 37 gill rakers on the first gill arch. Body relatively deep (32% of SL); first pelvic ray only slightly produced, not extending to anus; pectoral fin reaching a vertical through base of last dorsal spine; depressed anal fin length 32% of SL; caudal fin deeply forked, both lobes produced into filaments. This is the first record of the family Symphysanodontidae from the Red Sea. Morphologically, the new species is most closely related to the yellowstripe slopefish Symphysanodon katayamai, which is widely distributed in the Central Pacific.
