Pellenes spiders can be found across the Afrotropical, Holarctic and Indomalayan realms. Pellenes obvolutus is endemic to Kenya. The female holotype was found during 1948 living on Mount Elgon at an altitude of 2,000 m (6,600 ft) above sea level. Other specimens have been collected in the local area. The spider lives in savanna and grassland, often in areas with Combretum trees. It is not known in any other areas of the country.
