Relevant Information:

Description: Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 5; Vertebrae: 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. Habitat: Some of the more remarkable fishes to be found in Neotropical rivers are the Glanapteryginae, a miniature subfamily of pencil catfishes that live entirely among the sand grains of the river bottom (Lujan, N. 2021). Etymology: Specific name is derived from the name of the rapids on the middle Rio Cuao where the first specimens were encountered.
