Dolichopodidae_Chrysotus laesus (male) is correct? Region Malá Fatra Terchová about 700 m above sea level. Thank you very much for your help. I made a photo of 22.05.2011.

It's very hard to say which species you are dealing with here, unless you collected the specimen itself and are able to check the colour of the pubescence on, and the colour of the fore coxa and trochanter. Also, the relative size of the 1st flagellomere of the antenna (3rd antennal segment) is important.
C. laesus has white pubescence on coxa I and has a more bluish body colour;
C. cupreus has a pale fore trochanter and partly pale fore coxa with dark pubescence. Both have a relatively small 1st flagellomere.
C. obscuripes has a large 1st flagellomere, dark coxa and trochanter I and dark pubescence. All these species have largely dark legs. There is another dark-legged species,
C. blepharosceles, with distinct ventral bristles in all femora. Hope this helps ...
