P. schwenkii can be distinguished from P. adusta by the numbers of anal fin rays (IV-41 vs. III-43) and the position of first rib (3rd vs. 4th vertebra). The genus Parapriacanthus is distinguished from Pempheris by four characteristics, including absence of the metapterygoid with a circular protrusion (vs. presence in Parapriacanthus), the mandible retroarticular semicircular (vs. hourglass-like in Parapriacanthus), presence of foramen of hyoid arch (vs. absence in Parapriacanthus), and the dorsal fin first pterygiophore not thin and rod-like (vs. thin and rod-like in Parapriacanthus). The study compared with the Apogonidae, Acropomatidae, Glaucosomatidae and Pempheridae families. The first of different characteristic is the third infraorbital has subocular shelf, second of different characteristic is in pectoral fin has smooth and strong coracoid, third of different characteristic the skeleton of pterotic is branch-shaped, fourth of different characteristic the small angle of actinosts and body axis. And found that has four different characteristics unlike with the Pempheridae and other families.
