Date 21/02/2013 - 26/02/2013.

A similar fly, photographed in Kafue National Park back in 2011, was identified by Jan Willem as Diasemopsis (or Chaetodiopsis) meigenii, in this post:

Might this be the same?
[Edit: - it is the same. Thanks again, Hans Feijen and Jan Willem]

Hello Will,
Hans Feijen, a specialist in Diopsidae, told me that this is a specimen of
Diasemopsis (or
Chaetodiopsis) meigenii. Probably a female.
Diasemopsis (or
Chaetodiopsis) meigenii is one of the most common species occuring from South Africa upto Arabia.

Fourteen month deja-vu - thanks, Jan! I shall update the title accordingly.
I suppose the differences in structure (thicker limbs, eyestalks) in the previous pictures (
http://www.dipter...d_id=44508) are male/female variation, or just variability within the population?
Thanks again,
William.
