The holotype specimen, IGM 6583, consists of a partial skeleton including a partial right nasal, 10 dorsal and 14 caudal vertebrae, the right coracoid, left scapula, both humeri and ulna, right III and IV metacarpals, periacetabular process of Right ilium, iliac peduncle of the right ischium, both femurs, tibiae, and fibulae, left talus, right and left metatarsals III and IV, and several proximal phalanges of the right foot.[7]

Latirhinus was originally thought to be similar to the saurolophine Gryposaurus. However, a 2012 study found its holotype, as originally defined, to be a chimera comprising both lambeosaurine and saurolophine remains; the holotype bones would've belonged to a lambeosaurine.^[7] While this position has been accepted by other researchers,^[10][11] there are still disagreements over where Latirhinus falls within Lambeosaurinae. The first cladogram shows Latirhinus as a basal lambeosaurine,^[10] while the second shows an alternate position as a derived member of Lambeosaurini.^[11]
