  • As Carangoides ferdau was previously reported based on its underwater photograph, morphological descriptions have been incomplete up to the presence in Korea. On the base of two samples collected at the coast of Jeju island, morphological characters of C. ferdau are described in detail. This species is characterized by having the forepart of second dorsal fin much prolonged, 7~8 transverse dark bands on body, and snout length almost equal to eye diameter. It is morphologically very similar to C. orthogroammus, but is easily distinguished in having transverse dark bands instead of yellow spot on the body of C. orthogroammus. Phylogenetic relationships based on the mitochondrial cytochrome b (1,141 base pairs) sequences shows that C. ferdau is closely related to C. orthogroammus, and C. dinema also has a sister group relationship with C. ablongus. Both genetic distances (p-distances) are 8.2%, respectively.
