Abstract
All the fish specimens of Neoclinus bryope species complex collected from Okinawa Island including the 2 specimens already reported as N. bryope are referable to N. 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 of N. okazakii and with specimens from Taiwan as well as N. lacunicola and N. toshimaensis specimens from Shirahama in the case of N. nudus. The habitats of N. okazakii and N. 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.
