This has some of us badly exercised. I have some photos from friends, each of them from a different physical fly, but very likely from the same species. One is from Harare Zimbabwe this year, one from Kwazulu Natal South Africa. The morphology of the fly is quite striking; note the antennae for a start! jonrichfield attached the following image:  [149.45Kb] |

OK, the foregoing was the Zimbabwe specimen. A get the genus would be impressive, and to get confirmation of whether it is known from South Africa, even more so. Now Natal:

It seems to me a Pachycerina, but I am not familiar with the African fauna.

To my untrained and non-expert eyes they look like Sciomyzidae. Greetings, Henrik |

Well thanks friends. That was informative, not least in that my first reaction to Sciomyzidae was "What nonsense", whereas pretty soon I found myself saying "What the..." Anyway, to have the family settled is a good beginning. Much appreciated. Scientists often display a human failing: whenever they get hold of some new bit of truth, they decide it is the whole truth.

Pachycerina or something close to it is correct

My thanks and congratulations in particular to Ruud van der Weele and Paul Beuk, who got the correct genus right off. Somehow this percolated down to nearer home and the Natal Museum, from where Burgert Muller wrote: "...this fly photo ended up at the museum via Diptera.info. for identification. It is a Lauxaniid, belonging to the genus Pachycerina (Identification by Dr. Ray Miller) A paper on them can be viewed at https://www.dropbox.com/s/scmxppirfhpsvfz/afin2E0502E0207.pdf?dl=0 Unfortunately the abdomen is obscured, so getting it to species will be nearly impossible." That article certainly settles the matter, I reckon. My thanks to all who contributed.
