Western Omo–Tana languages
The (Western) Omo–Tana or Arboroid languages belong to the Afro-Asiatic family and are spoken in Ethiopia and Kenya. The languages are: 
Arbore
Daasanach
El Molo
Yaaku
The first three have long been recognized as related; Bender (2020) adds Yaaku, whose classification had been obscure. The El Molo language of Kenya is nearly extinct. Notes
