SL, cross section of trunk roughly cylindrical at pectoral girdle and progressively more compressed towards caudal-fin. In lateral view, dorsal profile of body straight from snout tip to interorbital region, slightly convex to dorsal-fin origin, and slightly convex to end of caudal peduncle. Ventral surface of body convex from tip of snout to anal-fin insertion. Caudal peduncle smoothly continues profile of trunk region, with dorsal and ventral profiles slightly convex. Greatest body depth at dorsal-fin origin. Head wide, longer than wide, nearly trapezoidal in dorsal view. Eyes elliptical, covered by thin and translucent skin separate from surface of eyeball. Anterior nostril larger than posterior one, surrounded by fleshy flap of integument continuous with base of nasal barbel. Posterior nostril partially surrounded anteriorly by thin flap of skin. Seven branchiostegal rays visible in c&s individuals. Mouth subterminal, its corners laterally or slightly posteriorly oriented. Lower lip with conspicuous fleshy lobes along lateral limits, lobes situated internal to base of rictal barbels. Lower lip with anterior and, to lesser degree, anteroventral surfaces covered by small papillae. Anterior margin of upper lip rounded with numerous papillae. Barbels relatively short and with larger bases. Nasal barbel thick always surpassing posterior margin of eye but not reaching opercular patch of odontodes. Maxillary barbel reaching posterior tip of interopercular patch of odontodes. Rictal barbel reaching interopercular patch of odontodes. Interopercular patch of odontodes posteriorly elongate with 11 or 12 conic odontodes imbedded in flesh. Opercular patch of odontodes very small, with 10–12 thin odontodes with thick tips.

The new species was discovered in a small stream with clear water and moderate water flow at the altitude of approximately 600 meters above sea level. The specimens were collected under rocks and aquatic vegetation in a muddy bottom area bordered by riparian vegetation. The region is highly impacted by agricultural activity, more specifically eucalyptus monoculture. Rivers in the region are poor in both alpha diversity and specimen abundance.

Aligned sequences were obtained for 573 bp of COI from the reference set of 11 tissue samples of trichomycterines, the translation of sequences did not result in stop codons, indicating the amplification of functional domains. The nucleotide composition of the COI matrix was 29.8% (T), 26.8% (C), 25.1% (A), 18.3% (G), with a proportion of 400 invariables sites, 173 variables sites and 113 parsimony informative sites. The overall mean genetic distance based in the COI gene was 0.138±0.011. The genetic divergence between species was superior to 3% and the results show concordance with the morphological identification. The pairwise species comparison ranged from 0.5 to 24.1% (
