Chaetostoma lexa is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypostominae, the suckermouth catfishes.[1] This catfish is endemic to Peru where it occurs in the Huallaga River in the Department of Huánuco. This species reaches a standard length of 4.9 cm (1.9 in).[2] C. lexa was first formally described as Loraxichthys lexa in 2013 by Norma Juliana Salcedo-Maúrtua with its type locality given as Mariano Dámaso Beraun, vicinity of Tingo María, Cueva de las Pavas, Quebrada Luconyupe, at 9°22'15.1"S, 75°58'32.7"W, in Leoncio Prado, Huánuco.[1] When Salcedo-Maúrtua described this species she classified it in the new monospecific genus Loraxichthys, this is now regarded as a synonym of Chaetostoma.[3]
