背的软条 (总数) : 27; 臀鳍软条: 41; 脊椎骨: 70. Two terminal bulbs separated by a long interspace (usually 2.8-3 times length of distal bulb). Barbel 8.1% SL in large specimens, short 27% SL in small specimens. Terminal filament short, 3.9-9.4% SL with 2 short branches together about 2 distal-bulb lengths from the bulb. Distal bulb 1.4-2.1 times length of proximal bulb. Axis of stem pigmented, lightly in small specimen, moderately dark in large ones. External chevron-shaped or roundish striated area on stem pigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 in small specimens (Ref. 11333).
