背的软条 (总数) : 25; 臀鳍软条: 38; 脊椎骨: 68. Two terminal bulbs separated by a short interspace, 0.3-1.5 times length of distal bulb. Barbel 52-63% SL in specimens larger than 8 cm. Terminal filament long (11-22% SL except in smallest specimen; with 2-4 long branches arising closely together a short distance (less than 0.5 to about 1.3 distal bulb lengths) from distal bulb. All branches with very small bulblets and without sub-branches. Stem axis well pigmented except in smallest specimen (6.6 cm); stem between bulbs and proximal part of filament usually lightly pigmented. Middorsal paired spots under skin between occiput and dorsal-fin origin usually 8, sometimes 7 (Ref. 11333).
