Abudefduf caudobimaculatus

Abudefduf caudobimaculatus, commonly known as the Okinawa sergeant,^[2] is a species of damselfish in the family Pomacentridae. It is native to the Indo-Pacific, where it is believed to range from East Africa to Yakushima and Lord Howe Island, including Taiwan (where it occurs alongside its congeners Abudefduf nigrimargo and A. vaigiensis)^[3] and Indonesia.^[4] Although initially described in 1939, it was subsequently considered synonymous with Abudefduf vaigiensis, until a 2017 review conducted by Kunto Wibowo of the Indonesian Institute of Sciences, Hiroyuki Motomura of the Kagoshima University Museum, and Minoru Toda redescribed it as a valid and distinct species.^[5] Despite this, it is still listed by FishBase^[3] and WoRMS^[6] as a synonym of A. vaigiensis.
