Robber Fly

Dear any,
This is really a spectacular looking Robber Fly in the family Asilidae.  We attempted to find a species identification and we found a matching photo of a mounted specimen on Beetles in the Bush that is identified as
Proagonistes praeceps, but alas, we have not been able to verify that identification elsewhere.  That specimen is from Natal, South Africa.  Beetles in the Bush provides contradictory information, calling it first a Hymenopteran and then a Robber Fly.  Diptera.info also has a photo of a mounted specimen and provides this information:  “Proagonistes sp., a large Laphriine asilid from East Africa or Madagascar (Andrenosomatini – related to Andrenosoma, Pogonosoma, etc.).”  This might be the only photograph online of a living specimen.  Can you provide any additional information on where it was sighted?

Update:  December 31, 2013
Upon researching a new image of an African Robber Fly that we just received, we discovered a recent posting on this genus on Ecology Picture of the Week.

    Hi, thank you for the feedback, this fly was about 50mm long, and we found it in the Isimasilingo Wetland Park, St Lucia, Kwazulu Natal, South Africa at a spot known as Mission Rocks. It was a ver hot and humid but clear day following a recent storm. The insect was sitting on the roof of a small car, hence it was clearly visible, giving me a fantastic opportunity to take some photos.
    Regards Stephan
