Nematogenys inermis is a kind of catfish, and the only extant species in the family Nematogenyiidae. This fish originates from fresh water in central Chile.[2]
The body is naked (without scales) and elongate. There are three pairs of barbels: chin (mental) barbels, maxillary barbels, and nasal barbels. There is no adipose fin. The opercle lacks spines.[2]
Nematogenyidae and Trichomycteridae are sister groups that together form a clade that is sister to the families Callichthyidae, Scoloplacidae, Astroblepidae, and Loricariidae.[3]
One extinct species, Nematogenys cuivi, has been described in this genus.
