Carangoides ciliarius is a dubious species of marine fish in the jack and horse mackerel family, Carangidae. The validity of the species has been questioned by a number of authors, with many concluding it is a synonym of the similar Carangoides armatus, commonly known as the longfin trevally. However, this synonymy has not been accepted by all authorities, with Fishbase and ITIS both recognising it as a valid species. Like Carangoides armatus, the species is occasionally referred to as the 'longfin kingfish'.

Taxonomy The species, as it is currently recognised, was scientifically described and named by the German naturalist Eduard Rüppell in 1830, based on the holotype specimen taken from Massawa in the Red Sea. Rüppell named the fish Citula ciliaria, placing the species in what was at the time a valid genus of jacks. As the classification of the carangids was reviewed, Citula was synonymised with Pseudocaranx, with C. ciliaria transferred to Carangoides, and the specific name changed from ciliaria to ciliarius, leading to the currently accepted combination. There is a possibility that Peter Forsskål described and named the species earlier, in 1775, which would make him the correct author under ICZN rules. He named a species Sciaena armata, but the description has been too vague to make any certain conclusions, and this name is considered a nomen dubium that cannot hold priority, and placed in synonymy with C. ciliarius. Georges Cuvier independently renamed the species as Caranx citula in 1833, also making reference to the name Caranx cirrhosus as a synonym of his new name.
