簡短描述
檢索表 | 型態特徵 | 形態測量圖
Two terminal bulbs separated by a short interspace, 0.6-1.7 times length of distal bulb. Barbel length 58-70% SL in specimens larger than 9 cm. Terminal filament 10-23% SL, except in some small specimens, with 2-3 (often 2) prominent branches arising closely together at 1-5 distal-bulb lengths, from the distal bulb in specimens to 11.4 cm SL (at 10 bulb lengths in a 20 cm specimen). Stem of filament proximal to major branches with widely-spaced tiny bulblets and without short basal branches; all long branches with very small widely-spaced bulblets (bulblets larger and more conspicuous in a 20 cm specimen). Barbel without melanophores (rarely very sparse pigment on axis of stem or filament). Middorsal paired spots between occiput and dorsal-fin origin probably 8, often diffuse or obscure (Ref. 11333).
