Ituglanis is a genus of small freshwater fish in the family Trichomycteridae native to South America.

Their greatest diversity seems to occur in the Amazon River basin.

[1] This genus was first erected for nine species previously classified in Trichomycterus.

[1] 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.

[3][4] Instead, it has been suggested to be the sister group of a large clade composed of the Glanapteryginae, Sarcoglanidinae, Stegophilinae, Tridentinae and Vandelliinae.
