Serranus defined by Robins & Starck (1961) with the following set of characters. Supramaxilla absent. Maxilla not covered by lachrymal. Premaxillary with a dorsal expansion. Teeth present on dentary, premaxilla, vomer, and palatine. Preopercle serrated. Opercle with three spines. Dorsal fin continuous. Caudal fin with 17 principal rays. Branchiostegal rays number 7. Snout, jaw area, and brachiostegal area naked. Scales encroach on bases of median fin membranes. Lateral line arched and continuous.


Body mauve to bluish above grading to whitish below. Six brownish body bands are variably expressed. Bands become more yellow on the belly. Two distinct blotches on mid-body, one under junction of spiny and soft dorsal fin and the other on the caudal peduncle. Head brownish above and pale below with a faint yellowish eyeband. Dorsal and caudal fin pale with faint brownish bands connected to body bands. Anal and pelvic fins pale. Eye greenish to golden.


Formerly placed in the genus Centropristis, but phylogenetic evidence places this in the clade of the elongate Serranus.
