Description complète des menacesExpert

This species experiences continuing decline in EOO, AOO, habitat quality, number of locations and number of mature individuals because of habitat destruction due to forest exploitation, mining and shifting cultivation. 7 specimens of this species have also been collected in the conservation zone surrounding the footprint of a mining project undergoing intense human pressure such as forests clearing. This forest should be subjected to protection in the near future. Ten other specimens are known from several unprotected forests subjected to selective logging, timber harvesting for small-scale subsistence and tavy (slash-and-burn farming).
