Ituglanis is a genus of small freshwater ray-finned fish belonging to the family Trichomycteridae, the pencil and parasitic catfishes. These catfishes are found in South America. Their greatest diversity seems to occur in the Amazon River basin. [2] Most species inhabit leaf litter, with several species living in caves. [2]

This genus was first erected for nine species previously classified in Trichomycterus . [3] Ituglanis is believed to be a monophyletic group. [3] There may be two monophyletic groups within this genus. [2] Ituglanis is currently considered a member of the subfamily Trichomycterinae though its position as a member of any of the current subfamilies has been questioned. [4] [5] Instead, it has been suggested to be the sister group of a large clade composed of the Glanapteryginae, Sarcoglanidinae, Stegophilinae, Tridentinae and Vandelliinae. [2]

Species

There are currently over thirty recognized species in this genus: [6]
