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
[edit]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
[edit]Trichogenes species are endemic to southeastern Brazil.[5]

- Trichogenes beagle de Pinna, V. Reis & Britski, 2020
