Ogasawaracris gloriosus
A grasshopper from Ogasawara Islands it was discovered in summer 2004.
This species had 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.
Habitat lost made this species extinct and it was already very rare when it was forst discovered.
It is know extinct.

Orthopterists have visited the Ogasawara Islands and conducted an intense search and collection of Orthopteran insects (Yamasaki 1988); nevertheless, only a few specimens of this species have been collected, and since 1984, no specimens have been collected. It is considered to be threatened with extinction or already extinct in the Ogasawara Islands. Therefore, it is worth describing this species even though the description is based on only three specimens.
This grasshopper species appears to be endemic to the Ogasawara Islands but its origin is not yet known. It also could be threatened with extinction
or already extinct. Efforts are necessary to determine if the grasshopper still exists on the islands and if so, conservation measures should be put into place to protect it.

The species is very unknown. I didn't know it until I read this thread. It is listed as CR in Japanese Red Data. Its two specimens collected in Hahajima are stored in Hokkaido University. Its third specimen collected in Chichijima was rediscovered in the National Institute for Agro-Environmental Sciences in Tsukuba. After the description in 2003, the forth specimen was rediscovered in National Taiwan University! There are very a few sources in Japanese websites. Only the article in English by Dr. Ito (above) is more detailed and reliable than any sources. The species was collected last in Hahajima in 1984 because of the introduction of alien frogs around the 1940s - the 1960s to get rid of insect pests.
