Description complète des menacesTexte détaillé évaluation IUCNExpert

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, annual fire, mining and shifting cultivation. 12 specimens (6 unique occurrences) of this species have been recorded on the footprint of a mining project undergoing intense human pressure such as forests clearing. This former subpopulation must be considered as extirpated. Four other specimens are known from several unprotected forests subject to selective logging, timber harvesting for small-scale subsistence and tavy (slash-and-burn farming).
