État de la populationTexte officiel évaluation IUCNExpert
The single population known is from a small gorge in the savanna area, hanging from the gorge walls over a distance of several hundred meters. The size of the main subpopulation is estimated at 1,000 individuals (A. Hemp pers. obs.); a second subpopulation consists of five individuals. Altogether seven localities have been observed, mostly with few individuals, with a total population of just over 1,000 specimens.
Despite a search this taxon has not been found in any other site in a wider area; the investigator has been working in this area for twelve years.

Description complète des menacesTexte détaillé évaluation IUCNExpert
This taxon does not occur in any protected area. The habitat, though several hundred metres long, is now fragmented due to the removal of the former tree cover in many places; this is a densely populated area and firewood collecting and expanding agriculture is encroaching on this gorge. An estimated 30% of tree cover has been removed (as of March 2013); in sites where tree cover has been removed, a rapid decline in specimens of this taxon has been observed.
