Justification
This species has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. It has also been assessed regionally as Least Concern for western Africa. Due to limited information on this species distribution and threats, it has been assessed as Data Deficient for eastern and north eastern Africa. Within north Africa, the species may no longer found in the region. Its type locality is near Cairo, and it is now only found in Lake Nasser in Egypt (outside the region). The impacts of the Aswan High Dam (constructed 1970) is thought to be the reason for the extirpation.
