Trichogenes claviger is a critically endangered catfish native to the Atlantic Forest of Brazil.
Habitat and distribution
The species is known from only from the Mata de Caetés (Caetés forest), a remnant of the Atlantic Forest, in Vargem Alta, Espírito Santo, Brazil. Here, the fish lives in small streams that are part of the catchment area of the Itapemirim River. This forest is primary, mountainous rainforest interspersed with plantations of exotic trees. It was first discovered in a small shaded stream, the Picada Comprida, within primary rainforest at an altitude of around 1150 m. The stream is ca. 30 cm deep, slow flowing and has brown but clear water. The stream bed is sandy but partly covered with dead leaves and other organic material. The fishes tend to occur in midwater. It is the only species of fish to occur at the locality.
