Vaghri, Aer, and the Koli dialect cluster are sometimes included, but Koli is also classified as Sindhi, and Aer is closest to Koli. A language called Vaghri are classified as Bhil, and it's not clear if this is the same or a different language. It's also not clear if Jandavra is Sindhi or Gujarati.
