Assessment Information [top]

Red List Category & Criteria: Vulnerable B2ab(i) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Cumberlidge, N.
Reviewer(s): Crandall, K. and Daniels, S. and McIvor, A.
Listed as Vulnerable. Although its extent of occurrence (range) is believed to extend throughout Malawi and exceed 20,000 km², it is believed that area of occupancy is likely to be < 2,000 km² since the species is restricted to rivers and streams. Currently it is known from seven locations (although further surveys may show that it occurs in more than 10 localities). A continuing decline in the extent of occurrence is inferred from the paucity of recent collections anywhere in its range. Potamonautes montivagus has been known to scientists for more than 50 years and yet still has only a poor representation in museum collections, and it has not been collected recently (in the past 30 years).
