Archoplites interruptus is not closely related to GSF , BG or LMB. More closely related to the Ambloplites like Rock bass. So JHAP may be on to something. Note of all the Centrarchidae, Sunfishes , Ambloplites (closely related to Archoplites) does not have hardly any reproductive compatibly with the lepomis and Micropterus . That would be an interesting test to see if Archoplites will cross with any of DIED's fish - my guess is no.
