2a. One spine on the first proximal dorsal pterygiophore.............................................. Leiopotherapon
2b. Two spines on the first proximal dorsal pterygiophore......................................................... 3
3a. Mottling pattern present at caudal base; lack of a foramen for exit of blood vessels from the third hemal arch anterior to the parahypural vertebrae.......................................................................... Amniataba
3b. No mottling pattern present at caudal base; foramen present for exit of blood vessels from the third hemal arch anterior to the parahypural vertebrae.................................................................................. 4

7a. Body elongate; caudal peduncle distinctly long; small head relative to body length; 20–25 predorsal scales to the occiput; dis- tinctly concave dorsal profile slightly posterior to the orbit.............................................. Bidyanus
7b. Body stout (S. kimberleyensis, S. trigonicus and S. wunambal are exceptions); caudal peduncle moderately long; moderate sized head relative to body length; mostly <20 predorsal scales to the occiput (up to 25 in some particularly large Syncomistes specimens); dorsal profile straight or convex (S. butleri and S. bonapartensis are exceptions).......................... 8
8a. Usually with randomly distributed dark body blotches; vomerine teeth; distinctive leathery-textured flesh.......... Scortum
8b. Dark body blotches absent; flattened teeth; flesh not leathery................................................... 9
9a. Small mouth, nearly nonprotractile, with the posterior of the maxillary strongly curved ventrally; two distinct rows of teeth in each jaw, slightly laterally pointed; tooth rows continuous on both jaws..................................... Pingalla
9b. Medium to larger protractile mouth; nearly straight maxillary; single distinct outer row of teeth pointed laterally from lower jaw; lower jaw with dorsally directed, toothless medium bump......................................... Syncomistes
