Nakanaia
Nakanaia is a genus of leaf beetles in the subfamily Eumolpinae. It contains only one species, Nakanaia depressicollis. It was described from a single female specimen collected from Gisiluve, a locality in the Nakanai Mountains in east central New Britain. It resembles the genera Rhyparida and Rhyparidella, but differs from the former by its lack of a "Y"-shaped suture on the frontoclypeus, and from the latter by its pronotum being traversely depressed in the middle, and lacking a tooth on the underside of each femur of the legs. The genus is named after the type locality of the type species, the Nakanai Mountains.
