Scientific Name: Macrobrachium purpureamanus Wowor, 1999

Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) B1ab(ii,iii,v)+2ab(ii,iii,v) ver 3.1
Year Published: 2013
Date Assessed: 2012-06-22
Assessor(s): Wowor, D. & De Grave, S.
Reviewer(s): Cumberlidge, N. & Smith, K.
Justification:
Macrobrachium purpureamanus is only known from peat swamps on Kundur Island, Riau Archipelago, Indonesia (Wowor 1999). The species is only known from a black water creek at the edge of a peat swamp forest. In 1998 the peat swamps were under conversion to oil palm and rubber plantations, and now the peat land is likely to have totally been converted (D. Wowor pers. comm. 2011). This species is likely to be extinct and more survey work is required to see if the species is extant or not.
Date last seen: before 1998

Geographic Range [top]

Range Description:Macrobrachium purpureamanus is only known from peat swamps on Kundur Island, Riau Archipelago, Indonesia (Wowor 1999). The species is not likely to be more widespread as the habitat is very specific (peat swamps with highly acidic water 3.6-4.2 pH) and it has not been found in other peat swamps.
