简单描述 检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 0; 背的软条 (总数) : 0; 臀棘: 0; 臀鳍软条: 5; 脊椎骨: 51 - 53. Diagnosed from all congeners by the presence of three branchiostegal rays, posterior naris absent and the lack of pleural ribs. Differs further from both Typhlobelus ternetzi and T. macromycterus by the absence of eyes, and further distinguished from T. macromycterus by the presence of the nine caudal fin rays and five anal-fin rays and differs further from T. lundbergi by the presence of three laterosensory canal pores (Ref. 56682).
从所有的同类鉴定藉由有三个鳃条骨，在后部的鼻孔不存在与缺乏胸膜的肋骨。 进一步不同于 特氏绒鼻鲶〔Typhlobelus ternetzi〕 和 T. macromycterus 藉由缺少眼, 与进一步与 T. macromycterus 区分藉由有这九个尾鳍鳍条与五个臀鳍棘条而且进一步不同于 T. lundbergi 藉由有三个侧线管孔.(参考文献 56682)
