Holotype: MZUSP 42469 47.3m SL. Paratypes: MZUSP 50548 - 50566, 21.0-62.0mm SL.
Distribution
Known only from the type locality: Gruta Olhos d’Agua, Itacarambi, Minas Gerais, Brazil (15o06'05"S, 44o09'30"W).
Habitat
The cave is a resurgence which carries a perennial flowing stream. Water levels vary from dry to wet seasons and it is mostly in the latter that food is transported into the cave. The fish is found throughout the cave. It is isolated within the cave by waterfalls upstream and by canalisation downstream. The fish is a carnivorous generalist and eats predominantly earthworms and arthropods (including beetles, mayflies, Diptera and troglobitic isopods). There is a severe food shortage during the dry season and the fishes live on body tissue during this time and have a correspondingly low condition factor (Trajano 1997).
Systematics
The relationships of the Trichomycteridae are not currently fully understood but this species appears to be closest to T. paolence and T. proops (Carvalho and De Pinna 1986).
