Fishes ofNeoclinus from Okinawa with notes on the traits of their habitats

All the fish specimens ofNeoclinus bryope species complex collected from Okinawa Island including the 2 specimens already reported asN. bryope are referable toN. okazakii. Neoclinus nudus, hitherto known only from Taiwan, is newly recorded from Okinawa Island. These two species are redescribed on the basis of the specimens from Okinawa Island. The specimens from Okinawa are compared with those from Shirahama in the case ofN. okazakii and with specimens from Taiwan as well asN. lacunicola andN. toshimaensis specimens from Shirahama in the case ofN. nudus. The habitats ofN. okazakii andN. nudus are clearly separated in the waters of Heshikiya, Okinawa Island and the habitat of either species is rather particular in that it is exceptionally unoccupied by blenniids which are flourishing in the coastal waters of the Okinawa Islands.
