Lamontichthys is a genus of freshwater ray-finned fishes belonging to the family Loricariidae, the suckermouth armored catfishes, and the subfamily Loricariinae, the mailed catfishes. The catfishes in this genus are found in South America
The phylogenetic position of Lamontichthys remains uncertain. It has been considered to be sister to Harttia, whereas Lamontichthys shows much more similarities with Pterosturisoma microps of the monotypic genus Pterosturisoma, which only differs from Lamontichthys by the number of pectoral fin rays.[2] The genus Lamontichthys is classified in the subfamily Loricariinae in the family Loricariidae which is classified in the suborder Loricarioidei of the catfish order, Siluriformes.[3]
Etymology
Lamontichthys suffixes the Greek word ichthys, meaning "fish", onto the surname of teh American ichthyologist Francesca LaMonte, the describer of the type species as Harttia filamantosa in 1935.[4]
