Diagnostic Features: Teeth with strong erect cusps on most teeth of the dental band except for some more distal teeth, cusplets low or absent on almost all teeth, semimolariform but not bladelike. First dorsal fin with abruptly vertical posterior margin; pectoral fins narrowly falcate in adults. Total vertebral counts 175 or 176. Body without small black spots.
