Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): van der Straeten, E. & Kerbis Peterhans, J.

Listed as Endangered, because this species has a highly restricted range, the habitat has largely been destroyed through agricultural activities and there is continuing decline. There is a need for further survey work to determine if and where the species still survives, as it may have an even smaller extent of occurrence to qualify for Critically Endangered. If no traces are found it could possibly even be considered as Extinct.
