Distinguishing "long-term" African-Americans from more-recent African immigrants

As discussed in History of "Asian American" / "African American" nomenclature, the term African-American is a euphemism established to refer to Black Americans, but seems to be generally used to refer to those whose families have been in the United States for centuries (many of whose ancestors were originally brought to the U.S. as slaves).

More recently, there seems to have been a significant increase in immigration from Africa, and there are many new Americans from Africa who are somewhat culturally distinct from the "long-term" African-Americans described above.

Is there any existing terminology used to distinguish these two different groups?

The question is a request for distinguishing terminology that can be used to distinguish "African-Americans" (defined as Americans of African origin). I would use "multigenerational" African-Americans vs. "newly or recently immigrated/established" African-Americans. That would distinguish the earlier/original group from the latter more contemporary group.
