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.

2004 Endangered (EN)
1996 Lower Risk/near threatened (LR/nt)
