MENA region

Why is there no general term describing a race group for Middle Easterners and North Africans like how black would describe sub saharan Africans? Like people generally use Arab as a race when its an ethnic group since there is no official term for the collective ethnic groups in both North Africa and the middle east. People may claim its bad to group these together, however its the same in other race groups like how habisha is an ethnic group in Ethiopia, and their general race is Black which describes 100s of ethnic groups in Africa
