In addition to the three main groups of the Bunak people in Ainaro, there are two other smaller groups, which were moved from the region around Zumalai only during the Indonesian occupation. The first group lives in the villages of Civil (Sivil) and Lailima (both in Suco Cassa). The second group from the east of Suco Casa are two Bunak villages, Leolima and Hutseo (along with its subsequent offspring, Hutseo 2 village) are surrounded by vast Mambai settlements. The inhabitants of these four villages speak the northeast dialect, with the variations typical of Zumalai.
