背鰭 (合計) : 25; 臀鰭: 38; 脊つい: 68. Two terminal bulbs separated by a short interspace, 0.4-1.6 times the length of distal bulb. Barbel length short 37-44% SL in specimens over 8 cm SL. Three to 9 short, usually bulblet-tipped filaments and 2 long ones, arising together from distal end of distal bulb or from a short stem. Longest filament becoming 23-35% SL in specimens larger than 8 cm; 1 long filament with a prominent large bulblet. Distal bulb 1.2-2.5 times length of proximal-bulb. Axis of stem well pigmented; between bulbs variably pigmented, sometimes forming a dark spot or small cap at proximal end of distal bulb. External chevron-shaped or roundish striated areas usually unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
Body shape (shape guide): elongated.
