Eurydemus


Eurydemus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from the South Pacific, though many additional species have been described from Africa.

Taxonomy

The genus was first erected by the French entomologist Félicien Chapuis for a single species, Eurydemus insignis, reported from Australia and later Fiji. This species was later found to be a junior synonym of Rhyparida grandis, which itself was originally reported from New Caledonia. However, both the records from Australia and New Caledonia are possibly erroneous.
In 1965, British entomologist Brian J. Selman revised the genus, transferring all African species in it seen by him to Afroeurydemus and other related African genera. He suggested that it was almost certain Eurydemus was restricted to Fiji.
