I'm in trouble with this couple! I saw it in Berlin in July 2010. Somehow I am not able to find a good genus for these red-legged ones. Please help!
Thanks in advance, Sundew

How about Neoepitriptus setosulus ?

Ah - you posted a very similar couple here: https://www.flick...8338925526! I thought of Neoepitriptus, but in Reinoud's photo guide (https://waarnemin...ilidae.pdf) N. setulosus is described as "femora black with a red stripe on the backside; red tibiae apically black with darkened backside" - the pictured flies look dark grey, even the wings, while ours have a red/brown appearance. I wonder if the colouration might be thus variable. Maybe Reinoud will enlighten us.
BTW, Neoepitriptus seems to be included in Machimus now, as is Tolmerus.
Many thanks for your hint!
Regards, Sundew

These are Neoepitriptus setosulus for sure, because the ID is based on actual, captured specimens, and the fist link leads pictures of specimens that were eventually seen by Reinoud:

and the other:

I think your flies match N. setosulus quite nicely.

That is very convincing, dear Henrik, but I wonder whether Machimus arthriticus can be excluded with absolute certainty. Its ground colouration is reddish, too. Well, the black hairs on top of the occiput of M. arthriticus are lacking in my flies. So Neoepitriptus setosulus is the best choice indeed -thanks again!

In my opinion Henrik is right, this has to be N. setosulus. M. arthriticus is almost twice as big, has entirely black femora, dark tibiae and a more true Machimus appearance. As is usual with these genera there is quite some variability which makes it difficult to give an accurate description that fits all individual specimens :-) The shape of the genitalia is more important and in these pictures, the shape confirms ID....

And this is the final expert's statement - thank you, Reinoud!

I changed the title of those two threads relevant to this topic, so that others can find it more easily... Smile There are three threads now dealing with this not-so-common sp Smile
