In the past, there must have been other Senoi tribes. In the upper reaches of the Klau River west of Mount Benum, the mysterious Beri Nyeg or Jo-Ben are mentioned, speaking a language quite closely related to Cheq Wong people. The Jah Chong tribe, which could speak a dialect very different from the Jah Hut people was also reported. Several dialects associated with Besis (Mah Meri people) existed in the Kuala Lumpur area. Perhaps there were other tribes speaking Southern Aslian languages and live in areas that currently inhabited by the Temuan people and Jakun people, speakers of Austronesian languages.
