 Acanthistius joanae (Whiteblotched koester)

Hi Johan

Yes, the photographs are of the whiteblotch koester and it now has a name, Acanthistius joanae. The species was in Smiths as Acanthistius sp but my husband Phil always told his research assistant Joan Wright that he would name it after her. Joan retired to Port Alfred a few years back & was heard to say that she would probably be dead by the time Phil got around to naming the koester. Anyway Phil finally wrote his description of the new species and how it differed from other Acanthistius species & it was published this year - at least 25 years after the fish was first collected off Port Alfred.
