Platycaranx talamparoides

Atropus armatus differs in having the second dorsal-fin lobe long, greater than head length (vs. short, less than head length); head profile very steep (vs. sloped) and gill rakers (including rudiments) on first gill arch 31–37 (vs. 27–31).

Platycaranx chrysophrys differs in having the head profile just above mouth vertical (vs. gently sloped); scaleless breast area small, extending to pectoral-fin base only (vs. large, covering area above and in front of pectoral-fin base) and gill rakers (including rudiments) on first gill arch 27–31 (vs. 21–26).

Turrum coeruleopinnatus differs in a scaleless breast area short ventrally, often extending to distinctly behind pectoral-fin base (vs. long ventrally, often extending to second anal-fin origin); scaleless breast area small, extending to pectoral-fin base only (vs. large, covering area above and in front of pectoral-fin base) and gill rakers (including rudiments) in first gill arch 21–27 (vs. 27–31).

Carangichthys dinema differs in having brown blotches between bases of second dorsal-fin rays (vs. no markings); straight part of lateral line slightly shorter than curved part (vs. much shorter); scaleless breast area short ventrally, extending to pelvic-fin origin (vs. long ventrally, often extending to second anal-fin origin) and scaleless breast area extending uninterrupted to scaleless pectoral-fin base (vs. scaleless breast area separated from scaleless pectoral-fin base by a broad band of scales).

Atropus hedlandensis differs in having the second dorsal-fin lobe short, less than head length (vs. long, greater than head length); second dorsal-fin central rays long and filamentous in males >16.5 cm FL with (vs. central rays never filamentous); scaleless breast area short ventrally, extending to pelvic-fin origin (vs. long ventrally, often extending to second anal-fin origin) and scaleless breast area large, covering area above and in front of pectoral-fin base (vs. small, extending to pectoral-fin base only).

Platycaranx malabaricus differs in having the tongue greyish brown to brown (vs. white to pale grey) and gill rakers and rudiments on first gill arch 32–38 (vs. 27–31).

Carangichthys oblongus differs in having the second dorsal-fin lobe long, greater than head length (vs. short, less than head length); scaleless breast area extending to pelvic-fin origin (vs. extending to distinctly behind pelvic-fin origin) and a scaleless breast area separated from scaleless pectoral-fin base by a narrow to moderate band of scales (vs. scaleless breast area uninterrupted to scaleless pectoral-fin base).
