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 a lack of information on this species- distribution and status, as well as taxonomic uncertainty, it is listed as Data Deficient for eastern, northern and north eastern Africa. It is estimated that less than 5 % of the species is found in the central Africa region and it is therefore categorized as Not Applicable.
History:
2006 – Data Deficient (IUCN 2006)
