Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2010-06-29
Assessor(s): Juffe, D.
Reviewer(s): Smith, K.
Justification:
The species is only known from few sites in Sudan and Uganda and is also recorded from the lower Shire in the Zambezi catchment. Based on the species currently known distribution it has a small area of occupancy (AOO) and number of locations (based on the potential threat from invasive water hyacinth). However this is not considered to be at a level for a threatened category and is therefore listed as Near Threatened. With more surveys the species may be found to be more widespread and possibly qualify for Least Concern.

Geographic Range [top]

Range Description:Recorded from Sudan and Uganda. In Uganda it was recorded at 900 m on the Victoria Nile at the junction with Lake Albert, it has also been recorded at Lake Bisinia. However the species may be more widespread as the species has also been recorded from Malawi, in the Lower Zambezi (lower Shire river).
