This genus appears to be widespread in the Magdalena, Orinoco, Amazon, and Paraguay-Paraná River systems where they are most common in deeper waters.[1]
Xyliphius includes moderately sized aspredinids, ranging from 8.8–14.7 centimetres (3.5–5.8 in) SL.[1] Species of this genus are distinguished from all other aspredinids by having highly reduced eyes, toothless premaxillae, a row of fleshy papillae projecting anteriorly off the lower lip, flattened unculi and unculiferous tubercles flattened. These species also have the openings of the anterior nares with papillae and no dark saddles on the body.[1]
