ok, the 'tail' thing is ovipositor, an if it have one then it is female.

according to this: http://www.tolweb...idea/11174
this is Toxophoroides sp. (Ichneumonoidea )

No, I think this is not Ichneumonoidea. It is Chalcidoidea somewhere near Eulphidae/Torymidae.

Chalcidoids, being Hymenoptera, have two pairs of membranous wings as opposed to the single pair found in flies

I see only one pair of wings on my photo, or m'I missing something ?

There should be small hindwings there, although they are hardly visible on this photo.

hmm, as I read the hindwings can be wery small thus not visible here. There is a database, not having this species, but for future refernce:

Think it could fit into Torymidae/ Megastigmus

My guess would be Megastigmus sp. too ... I have a few specimens here that look very similar to your (very nice) photo :) If you can get hold of a copy of Peck et. al. (1964) it would be very worthwhile - it has an excellent key.

You will probably have to track it down in a museum library because I bought the last copy the publishers had :D
