Just like Capo readily admitted the considerable diversity of the Phla–Pherá branch, Kluge's analysis did not result in conclusive evidence regarding the exact make-up of the western and eastern Phla–Pherá branches – various modes of computation yielded different configurations of the respective dialects (cf. 2000:62–3, 2005:45ff). The diversity in this subfamily is probably due in part to the fact that the various Phla–Pherá communities do not occupy one specific geographical area but are scattered along the coast of the Bight of Benin.
