The new species differ from previously described members of this complex in other lakes, are phenotypically distinct, and assortatively mate in Lake Apoyo. The presence of endemic cichlids in each of the crater lakes suggests that sympatric speciation occurred. A key is presented for the species of Amphilophus found in Lake Apoyo.
