Scientific Name: Lapitiguana impensa
Species Authority: Pregill and Worthy, 2003
Not directly a Brachylophus sp, but the L. impensa did live on fiji many years ago. Fossils remains have been found on Viti Levu.
The fossils where found in the late quaternary sediments.
This iguanid is distinct from the living Brachylophus, by the presence of a parietal forarmen located in the frontal bone and an anterior inferior alveolar forarmen in the splenial.
The iguana seems to be basal among Iguanidae, but its relationship is unresolvable with the evidence available.
