As a shoreline species and not continuously spread within its habitat it is probable that it has an AOO of less than 20,000 km². It is known from one location at Dagusi Island and Lange has found the species at four sites in his survey work in the Kenyan part of Lake Victoria. Not much survey work has been undertaken in Uganda since 1950s. The habitat is also declining in quality through pollution, sedimentation and human disturbance.
