Abstract - Stegastes lubbocki is described from40 specimens collected at Ascension Island in the Middle Atlantic Ocean during 1977. It is primarily separable from the other 13 Atlantic members of the genus on the basis of its distinctive colour pattern consisting of dark brown (blue in life) on most of the body and fins with an abruptly pale (yellow in life) caudal peduncle and caudal fin. The largest known specimen is a mature female 50 mm SL, thus it is possibly the smallest Stegastes other species range from 70 to 140 mm SL.
