The Rungwe dwarf galago inhabits montane evergreen forests and bamboo forests. Specimens have been identified from several adjacent locations in Tanzania's Southern Highlands - Mount Rungwe, the Poroto Mountains, the Livingstone Forest of Kitulo National Park in the Kipengere Range, and Madehani Forest Reserve in the Kipengere Range. They are locally common in these forests, which cover an area of less than 300 km². Its range doesn't overlap with any other galago species.
