Pectoral-fin tip reaching base of tenth to fourteenth anal fin ray; no (rarely one or two) scales on predorsal midline.
Lateral profile of body with slight convex curve from first dorsal fin origin to moderately slender caudal peduncle; distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process broadly concave or with very broad medial notch and nearly smooth anterior edge terminating with moderately small triangular spine at each apical corner; predorsal space usually naked or with few large scales on periphery.
Second dorsal-fin spine slightly longer than first and slightly longer or subequal to third, subsequent spines progressively shorter; tips of pectoral fins reaching base of about tenth to fourteenth anal fin ray, first free pectoral fin ray reaching base of second anal fin ray.
