Diagnosis |
A single, ovoid terminal bulb 0.8-1.8% SL, with nipple-like distal protuberance. Barbel 41-58% SL. A single but complex terminal filament with 2 long branches arising together near its base, followed by 1-5 large bulblets, then by 2 shortest branches arising together, each usually with a prominent large bulblet; all branches and the main filament with numerous, prominent small bulblets. Filament length 12% SL. Axis of stem lightly or unpigmented; a prominent, wide, black circle forming a cap at base of terminal bulb. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin usually 7, sometimes 8. Anterior margin of fleshy orbit with a distinct slender pedicel extending posteriorly over the eye (Ref. 11333). |
