Taxonomy & naming
Trichomycterus pinedai was described in 2026 by Carlos A. Ardila Rodríguez, in a Spanish-language paper (with English abstract) published in the Barranquilla-based series Departamento del Atlántico. It belongs to the family Trichomycteridae, subfamily Trichomycterinae, genus Trichomycterus — the largest genus in the family by far, with well over 200 described species distributed from lowland South America into high-Andean streams.
The holotype, CAR 1062, was collected at Vereda Gallinera, in the municipality of Vegachí, Antioquia Department, Colombia, at an elevation of about 972 meters, with seven paratypes (CAR 1049) from the same site. The Catalog of Fishes (Eschmeyer, California Academy of Sciences) records Trichomycterus pinedai Ardila Rodríguez, 2026 as the currently valid name. The original description was not accessible in full for this article; the account here relies on the Catalog of Fishes record and the paper's formal citation only.
Morphology
No morphological description, measurements, or coloration details for Trichomycterus pinedai were accessible for this article. Like other members of its genus, it is presumably a small, elongate, scaleless pencil catfish, but no species-specific data can be confirmed here.
Habitat
Trichomycterus pinedai is known only from its type locality, a stream at Vereda Gallinera in the Río Magdalena basin, Vegachí Municipality, northeastern Antioquia, Colombia, at roughly 972 meters elevation — a mid-elevation Andean tributary setting typical for many species in this genus. No water chemistry data have been reported.
Feeding
No diet information has been published for Trichomycterus pinedai. At the genus level, Trichomycterus species are free-living benthic invertebrate feeders, using their barbels to locate prey among stream substrate — a reasonable presumption for this species, but not a documented fact.
Mating
No courtship or spawning behavior has been recorded for Trichomycterus pinedai.
Breeding
Breeding biology is entirely undescribed for this species; it has never been kept or bred in captivity.
In the aquarium
Trichomycterus pinedai is not in the aquarium trade and has no husbandry record. Genus-level, small Andean Trichomycterus species are typically kept as cool-water, well-oxygenated stream fish, but none of this has been confirmed for T. pinedai, and no care guidance can responsibly be offered.
Conservation
Trichomycterus pinedai has not been assessed by the IUCN Red List and carries no formal conservation status. It is currently known only from its single type locality; no information on population size, trend, or threats has been published.
