Platycaranx malabaricus

Atropus armatus differs in having the second dorsal-fin lobe long, greater than head length (vs. short, less than head length); second dorsal-fin central rays filamentous in males >21 cm FL (vs. never filamentous); scaleless breast area short ventrally, extending to pectoral-fin base (vs. long ventrally, extending to second anal-fin origin) and scaleless breast area small, extending to pectoral-fin base only (vs. large, covering area above and in front of pectoral-fin base).

Platycaranx chrysophrys differs in having the head profile just above mouth vertical (vs. gently sloping); scaleless breast area short ventrally, often extending to behind pelvic fins (vs. long ventrally, extending to second anal-fin origin) and gill rakers (including rudiments) on first gill arch 21–26 (vs. 32–38).

Turrum coeruleopinnatus differ in having scaleless breast area short ventrally, often extending to pectoral-fin base (vs. long ventrally, 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) on first gill arch 21–27 (vs. 32–38).

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) and scaleless breast area short ventrally, extending to pelvic-fin origin (vs. long ventrally, often extending to second anal-fin origin).

Atropus hedlandensis differs in having a 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 (vs. never filamentous); scaleless breast area shorter ventrally, often extending to pelvic-fin origin (vs. long ventrally, extending to second anal-fin origin) and scaleless breast area large, extending to area above and in front of pectoral-fin base (vs. small, extending to pectoral-fin base only).

Carangichthys oblongus differs in having second dorsal-fin lobe longer than head (vs. shorter than head) and blue/black blotches between bases of second dorsal-fin rays (vs. no markings).

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