Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335); sensitivus: The name sensitivus is from the Latin sintio, sensus, to perceive by the senses or feel, in reference to the numerous pitline sensory organelles characteristic of this species (Ref. 85567).

背棘 (总数) : 0; 背的软条 (总数) : 11; 臀棘: 0; 臀鳍软条: 8; 脊椎骨: 39. Diagnosis: This species differs from all other small species of African barbs by its very slender caudal peduncle; it is distinguished from the great majority of small African barbs by its exceptionally well developed sensory papillae or pitline organelles which cover most of the head in both sexes; similar pit lines occur on the scales covering the body; males differ from those of most other species of African barbs of similar size in having the rostrum and dorsal surface of the head covered with numerous breeding tubercles (Ref. 85567).
Found in very swift water, with bottom of coarse gravel and smooth water-worn stones (Ref. 85567).
