Lake Poso belongs to the two ancient lake systems on Sulawesi (Indonesia). It is a solitary lake approximately 80 km NW of the Malili lakes. Lake Poso is deep (- 450 m, 323.2 km²) and of tectonic origin. Species flocks are known from a couple of taxa with pachychilid gastropods being the best studied group to date.
