Itacuphocera (pe-taxon #22)
This is a lovely, tiny little tachinine tachinid – shiny, jet black all over with a yellow head and red eyes. Unusually for this subfamily it also has a petiole on the median vein. In fact the median vein has a completely remarkable shape.
EDIT (04/10/2010): This isn’t a great fit but it seems to me to be close to Itacuphocera sp.
