A review of P olynesian C arposina H errich‐ S chäffer ( L epidoptera: C arposinidae), with descriptions of four new species

H awaiian C arposina represent over 17% of the known world fauna of C arposinidae. In contrast, only two species are known for all of F rench P olynesia in the S outh P acific. Here we describe four new species: two from the H awaiian I slands, Carposina urbanae sp. nov. and C. gagneorum sp. nov. , and two from the S ociety I slands, C. longignathosa sp. nov. and C. brevinotata sp. nov. We further recognize another new H awaiian species too worn to describe. Additionally, we present the first phylogeny for P olynesian C arposina , including 19 taxa, using one mitochondrial and two nuclear gene regions. The H awaiian C arposina sampled thus far form a monophyletic clade. Lastly, we provide a framework to better understand the diversification and phylogeography of this group, and provide a summary of currently known host plant associations. Diversification appears to have resulted from interplay between host switching and geographic isolation across the H awaiian A rchipelago.
