Dear Cranefly,
I am sorry to tell you (and the others will agree with me when they look more closely) that none of the previous identifications are correct:
1. specimen in the centre:
Syntormon: is not
fuscipes, but rather
monilis (male): see the deformed front tarsus and the enlarged apical tarsomere of the mid leg. The metatarsus is similarly ornamented as in fuscipes which might have caused the confusion.
2. specimen at the left hand side:
Gymnopternus: incorrect, is rather a female of
Rhaphium (possibly but not necessarily
appendiculatum). See the rather sinuous course of the vein R4+5 and M1+2, and the apical postpedicel.
3. specimen at the right hand side:
Dolichopus: incorrect, rather a female of
Sybistroma nodicornis. See the absence of bristles on the hind metatarsus, and the scape and pedical with pale lower half, together with the protruding clypeus.
I guess these flies were collected near a very humid marshland with open water, muddy spots and some canopy by trees?
With kind regards,
Marc

You are right, Marc, regarding
Syntormon: it is
monilis in traditional sense (Parent, 1938) [
S. monilis (Haliday) sensu Parent]. Unfortunately Parvu (2009) recently confined its distribution to the type locality (England, Ireland), considering his
Syntormon silvianus Pârvu, 1989 the Pan-European species instead of monilis. At the same time, I guess that silvianus is a synonym to
Syntormon submonilis Negrobov, 1975. See extracts from the DoliBank:
