Cobitiglanis Fowler, 1914 Henonemus is a genus of pencil catfishes native to South America.

Though the monophyly of Henonemus has previously been in doubt, leading to this genus being placed in synonymy with Stegophilus.

[1][2] There are currently five recognized species in this genus:[3] H. intermedius originates from the Araguaia River basin in Brazil.

[2] H. triacanthopomus has been collected in the Apure and Arauca Rivers and in Caño Macareo in the Orinoco Delta, but is probably distributed through the entire middle and lower reaches of the Orinoco River basin.

[1] Fish of the genus Henonemus have an opercle with two odontodes (though H. triacanthopomus differs from other Henonemus in that there are three or four odontodes in specimens greater than 80 millimetres or 3.1 in SL) and the teeth of the most posterior row on the premaxilla and the dentary proximally turned to the midline then abruptly bent laterally in the distal half, and arranged in a compact band.
