Lol, nice to know it's a female Andre.:) The distance between the eyes might be the clue there, but flies can be confusing sometimes. Now at least I know it's only the males which have a hypopygium!:P
I now see there are three possibilities for here, strigatus, funeralis and ornatus, and as the key description for the ocelli seems to fit the last fly it should not be so difficult? I haven't yet got around to trying to key the other two I had but it looks very different so should be the other likely species we have. E. sabulonum is very rare and so far only 8 records on the west coast since 2000.
Oops, somehow I got the two in 21 muddled, must have been too late. ;) This is what I thought matched my last fly, which is 21b and should have been
Eumerus amoenus which isn't here, but I don't think the 'jizz' note appied to 21b or does it?
Ocelli located on the middle of the vertex, distance between front ocellus and both hind ocelli equal to or somewhat longer than the distance between hind ocelli and hind margin of the eyes;
Back to square one :o
