Diagnosis

Dorsal fin X-XIII (typically XII), 18-21 (rarely 21), spinous and segmented-ray portions continuous. Anal fin II,17-22 (typically 19-21). Pectoral fin 14-16 (typically 15). Segmented caudal-fin rays 13 or 14 (rarely 14). Vertebrae 10 or 11 (rarely 10) + 23-26 (rarely 23) = 34 to 37 (rarely 34). Dentary incisor teeth which includes anterior canines very similar in appearance with incisors, 40-53 (rarely < 44); posterior canines 0 or 1(usually 1) on each side. Lateral line lacking vertical pairs of pores, extending posteriorly to point between verticals from 8th and 12th from anterior most dorsal-fin spine (usually past vertical from 8th). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Body coloration of 3 basic color patterns: uniformly brown, dark-brown or black but pigmentless posterior of dark caudal fin base, or generally brownish with darker stripe along dorsal area.
