Ogasawaracris gloriosus, a new genus and species of possibly extinct grasshopper (Orthoptera: Acrididae) from the Ogasawara Islands

A new grasshopper genus and species of the subfamily Eyprepocnemidinae, Ogasawaracris gloriosus, is described from the Ogasawara Islands, oceanic islands south of Japan. This species has unique characteristics, such as an extraordinarily large body, rugose and very coarse punctation on the lateral surface of the pronotum, and very strong pronotal lateral carinae. Specimens of this new species have rarely been collected and they are known only from the Ogasawara Islands. The species may already be extinct.
