There was a debate whether the "Dicerorhinus sumatrensis lasiotis" specimen should be considered as a separate subspecies from the similar nominate "Dicerorhinus sumatrensis sumatrensis" specimen from Indonesia. However, it remained a subspecies as the northern Sumatran rhinoceros was significantly larger, with unusual longer hair on the ears, and longer and bigger horns.
