簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 21 - 25; 臀鰭軟條: 35 - 42. Body black, elongate and slender; depth 5-8% SL. Long, tapering protrusible snout. Slender barbel stem and two terminal bulbs. Barbel stem has little or no external pigment (Ref. 37039). Two terminal bulbs separated by a short interspace, less than half to 1.5 the length of distal bulb. Barbel length increasing to 70-91% SL in specimens 10.5-15 cm, apparently decreasing in large females (17.9-25.3 cm) to 46-51%. Terminal filament short (9% SL or less, slightly longer to 5 times longer than distal bulb) with 2 well-developed side branches arising just distal to bulb and often other branches along its length. All branches with prominent internal bulblets, some nearly the same diameter as branch, resulting in a series of swellings in many specimens. No melanophores in stem, between bulbs, or in filaments in specimens up to 15 cm SL; none between bulbs at any size. Middorsal paired spots under skin between occiput and dorsal-fin origin usually 8, sometimes 7 (Ref. 11333).
身體黑色的﹐細長的與細長的; 深度 5-8% SL。 長的, 尖端細的能伸展的吻。 細長的觸鬚莖與二個末端的球莖。 觸鬚莖有少或沒有外部的有顏色。 (參考文獻 37039) 被一個短間隙分開的二個末端的球莖, 少於對 1.5 末稍球莖的長度的一半。 觸鬚長度對在標本中的 70-91% SL 增加 10.5-15 公分, 顯然地對 46-51% 在大的雌魚 (17.9-25.3 公分) 中減退. 末端的絲狀突起短 (9% SL 以內, 些微地更長的對倍 5 末稍球莖) 有兩個出現的發展良好的支流正好末梢部對球莖與時常其他的分支沿著它的長度。 所有的分支有突出的內在球莖, 一些幾乎如同分支一般的直徑, 在許多標本中造成一系列的膨脹。 在莖中的沒有黑色素細胞, 在球莖之間, 或在標本的絲狀突起向上到 15 公分 SL; 在任何的大小在球莖之間的沒有。 在後腦部與背鰭起點之間的皮膚下面的背面中央的成對斑點通常 8, 有時 7.(參考文獻 11333)
