Scientific Name:

Ancharius fuscus

Species Authority:

Steindachner, 1880

Common Name/s:

English

–

Vaona

Synonym/s:

Arius fuscus (Steindachner, 1880)

Assessment Information [top]

Red List Category & Criteria:

Data Deficient ver 3.1

Year Assessed:

2004

Assessor/s:

Loiselle, P. & participants of the CBSG/ANGAP CAMP "Faune de Madagascar" workshop, Mantasoa, Madagascar 2001

Reviewer/s:

Stiassny, M.L.J., Sparks, J.S. (AMNH, New York) & Darwall, W (Freshwater Biodiversity Assessment Programme)

Justification:
The distribution range of this species was thought to include the east coast rivers between Antananbalo and Mananjary, Madagascar. However, recent research suggests that A. fuscus and A. brevibarbus are complexes of allopatrically distributed species. In light of this evidence, the assessment for both taxa becomes Data Deficient. Prior assumptions regarding range and population size are no longer valid.

History:
