What does Romans 16:8 mean?

Paul continues to list people whom he would like his readers to greet for him. Paul apparently knew quite a few people in Rome, and it's a long list. Very little specific information is known to us about many names on the list, including the one in this verse.

For the second time, Paul refers to someone as "beloved." He calls Ampliatus his beloved in the Lord. Perhaps Paul had an especially close relationship with this man or perhaps Paul merely wished to say something kind about Ampliatus. Paul had instructed his readers to love all Christians in the Lord (Romans 12:10).
