I did not manage to look at the genitalia yet. However, there are some distributional and morphological differences, so it would be premature to reject wahlbergii. However, if you know a paper on this issue I am not aware of, please let me know.
There are a few cases where the male genitalia of two closely related species are not distinguishable, however, the femelas clearly show differences. I remember a case in the genus Catasigerpes. So, just a generic revision may clarify the situation (or not...). The possibilities are: 1. the three species are maintained; 2. at least wahlbergii may become a subspecies of ocellata; 3. ocellata is the only, very variable species.
