Thanks for your answer Igor, but I don't think it is right. I think the poor quality of the images may have misled you. The lower postocular cilia of this Dolichopus are pale and for D. rupestris they should black as far as I know. I tried to make some pictures in the daylight, but I fear my equipment is just not good enough. So I will additionally list some of the key characteristics (hoping it will give a clue) 1. All femora and tibia yellow (Black at apex of hind femora) 2. Lower postocular cilia pale 3. Tarsi simple, hind metatars with > 2 dorsal setae 4. No long hairs on hind femur 5. Front tibia without long apico-ventral bristle 6. Antenna black (entirely) 7. Face silvery white and hairy (bit) This brings me to D. albifrons in your key, which is as far as I know not known from The Netherlands Auratus attached the following image:  [172.29Kb] Greetings, Jan |

It is Dolichopus excisus which is unknown in Scandinavia.
