This is a widespread species recorded from localities wide apart (west Uganda, west Kenya and west Tanzania), a wider distribution in between these localities and in eastern Democratic Republic is assumed. More surveys are needed. No known major widespread threats are known to this species, which is assessed as Least Concern and unlikely to be declining fast enough to qualify for listing in a threatened category.
In eastern Africa, it is listed as Near Threatened in view of its limited range of occurrence (west Kenya and Uganda) and habitat restriction (forest streams). At the moment the populations in the forests seem to be stable and only an increasing habitat destruction will make it necessary to raise the Red List Assessment. More surveys in the Congo area are needed to check, whether O. styx has a wider range of occurrence westwards.
