Trichogenes is a genus of pencil catfishes. It is currently the only genus within the subfamily Trichogeninae.
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.[2]
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.[1]
Distribution
[edit]Trichogenes species are endemic to Brazil.
Species
[edit]There are currently three recognized species in this genus:[3]
- Trichogenes beagle de Pinna, Reis & Britski, 2020
- Trichogenes claviger de Pinna, Helmer, Britski & Nunes, 2010
