After the failed rebellion of Manufahi, a part of the Bunak people of Loti was moved by the Portuguese to the location of today's Loti. Others were settled in two new villages in Suco Betano. One of them is Bemetan as it is known in Mambai language or Il Guzu (meaning "black water") in Bunak language, and the second being Leoai (Leo Ai / Leouai). During the Indonesian occupation, Bunak people who remained in the old Loti was also relocated to the new Loti. These three villages share their own extraordinary dialect.
