In page Sumatran rhinoceros:

"

D. s. lasiotis, known as the Northern Sumatran rhinoceros or Chittagong rhinoceros, which once roamed India and Bangladesh, has been declared extinct in these countries. Unconfirmed reports suggest a small population may still survive in Myanmar, but the political situation in that country has prevented verification.[9] The name lasiotis is derived from the Greek for "hairy-ears". Later studies showed that their ear-hair was not longer than other Sumatran rhinos, but D. s. lasiotis remained a subspecies because it was significantly larger than the other subspecies.[6]
