簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 24; 臀鰭軟條: 35; 脊椎骨: 67. A single terminal bulb, its length more than twice its width, with a terminal projection that may be undeveloped or up to 55% of bulb length. Bulb and projection combined 0.8-2.2% SL. Barbel 67-83% SL, except in the smallest specimen. Axis of stem moderately to fairly dark pigmented proximally, becoming lighter or unpigmented distally. External chevron-shaped or roundish striated areas unpigmented, becoming closely spaced distally. Widely spaced spherical inclusions present in distal 1/3 to 1/2 of stem, sparse or absent before bulb. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 9 (Ref. 11333).
一個末端的球莖, 它的長度超過兩次它的寬度, 具有一個可能是的末端的突出未發展的或者向上到 55% 的球莖長度。 球莖與突出聯合了 0.8-2.2% SL 。 觸鬚 67-83% SL, 除了最小的標本。 莖的軸一般到非常深色的近端地, 末梢部地變成顏色淡或沒有顏色。 外部的鋸齒形或圓的有條紋的區域沒有顏色, 變成末梢部地間隔很密的。 空隙大的圓球狀的包含出現在末梢部的 1/3 到 1/莖中的 2, 稀疏的或者在球莖之前不存在。 在後腦部與背鰭起點 8 之間的背面中央的成對斑點, 有時 9.(參考文獻 11333)
