Other characters that easily distinguish the new species, although not exclusive, are: highly reduced skin pigmentation (except for T. gorgona and caverestricted congeners, T. chaberti, T. itacarambiensis, T. spelaeus, T. sandovali, T. santanderensisand T. uisae); total loss of eyes, not visible externally (except for T. sandovali and T. spelaeus); barbels long, especially the nasal (99.3- 143.5% HL) and the maxillary (97.0-131.3% HL) (except for T. longibarbatus and T. spelaeus); scapulocoracoid with a conspicuous anterior process projected forward (except for T. sandovali, T. spelaeus and T. uisae), with a narrow base, a wide apex and a rounded distal margin; and pectoral-fin ray count reaching I,9 (except for T. hualco). Characters possibly exclusive, but about which many taxa lack information, are listed as complementary diagnoses: cranial fontanel unique, extending from the posterior half of supraoccipital to the posterior region of the frontal bones, with a conspicuous constriction on the meeting point of supraoccipital and the two frontal bones; supraorbital long and cylindrical, without projections, with a needle appearance; 27-29 interopercular and 16-19 opercular odontodes (Ref. 87887).

The only cave entrance so far known opens into a large room with a lake, whose level increases during rain seasons, completely flooding the saloon and only allowing access through cave diving from the entrance. Trichomycterus dali catfishes can be found in the permanently dark areas zone, calmly swimming in the water column and close to the rocky substrate (bottom and walls). In Buraco das Abelhas, individuals were observed from 12 up to 55 meters deep (maximum depth of the cave system); in Saracura cave, fish swim from near the surface up to a depth of 65 meters, where the main tunnel stops dropping down and become horizontal. The light from halogen underwater spotlights, 50W, used at the time the first specimens were collected, as well as from 10 to 20W HID spotlights used more recently, did not trigger any visible reaction in these fishes. Cave divers also seem not to disturb the fishes, but, as one try to catch them, they start to swim very fast towards the deeper parts of the caves, against the current, near the bottom and into small crevices. Sometimes they were observed digging the soft bottom of Buraco das Abelhas. Rizzato, P.P., E.P.D. Costa Jr. and M.E.
