Trichogenes is a genus of freshwater ray-finned fish belonging to the family Trichomycteridae, the pencil and parasitic catfishes.[1] It is currently the only genus in the monogeneric subfamily Trichogeninae. These catfishes are found in South America.
A third species, T. beagle, was described in 2020 from archival material of unknown origin. The occurrence of the new species in the wild is unknown.[4]
Etymology
The name Trichogenes is composed of the words "Tricho", referring to its family, the Trichomycteridae, and "genes", referring to the genus Helogenes due to its superficial resemblance to the latter.[3]
Distribution
Trichogenes species are endemic to southeastern Brazil.[5]
