The generic name is a combination of the dinosaur genus name Tyrannosaurus and the suffix "molpus", referring to the relative large size of the genus to other chrysomelids endemic to New Zealand. The specific name, rex, is the Latin for "king", referring to the only known location of the genus, Three Kings Islands.[1]
A single specimen of the species was collected from Meryta sinclairii (also known as the puka), a tree endemic to the Three Kings Islands.[1]
