背棘 (總數) : 1; 背的軟條 (總數) : 6; 脊椎骨: 34. Possible a very small species. Snout moderately projecting; cheeks relatively expanded; head terete. Anterior naris very near snout tip (distance between naris and snout tip less than eye diameter). Nasal barbel extending to eye; maxillary barbel reaching only to end of pectoral fin; maxillary-barbel membrane broadly attached to head only on cheek; maxillary bone reaching posteriorly to midway between eye and end of head. Vent opening directly to exterior; vent and genital papilla located between anterior third of pelvic fins. Dorsal and pectoral fins without filamentous extensions Anal fin with 4-5 simple rays, 7-8 branched rays, total 11-13 (Ref. 40780).
可能的一個非常小的種。 吻一般突出; 頰相當擴大了; 頭部圓柱形的。 前面的鼻孔非常接近吻頂端。 (鼻孔與吻頂端少於眼直徑之間的距離) 延伸至眼的鼻骨觸鬚; 顎的觸鬚達到不料竟會胸鰭結束; 上頜骨-觸鬚薄膜寬廣地只有在頰上依附於頭部了; 上頜骨硬骨在後部地對在眼與頭部的末端之間的中途達到。 對外部直接地的排洩孔打開; 在腹鰭的前三分之一之間設置的排洩孔與生殖乳突。 背部的與沒有絲狀的延長臀鰭有 4-5 單一的鰭條， 7-8 分支條，總 11-13 的胸鰭.(參考文獻 40780)
