Arrived at Istocheta in the key at the same time you wrote it

We only have Istocheta longicornis listed in Sweden.
I will try to take all the photos necessary (if possible) to confirm that ID.
I'll be back later ...
#8
Following "Die Raupenfliegen Mitteleuropas:"
First sternopleural bristles...
#9
... and "swollen" sub-scutellum => Tachinidae
#12
19: m-cu almost right-angled, no small bristles on R4+5 => 25
#13
25: m-vein bent (see image above) => 30
#14
30: Cell R5 open (see image above) => 56
#15
56: Other combinations ... => 63
#16
63: Brigth hairs on the lower back of head => 76
#17
76: Some hairs as in abb. 8 (see image above) => 77
77: Once again as in abb.8 (see image above) => 78
78: As in abb.8 and eyes with some hairs (see image above)
=> Istocheta !!!
#18
Istocheta key:
1: Arista thickened to more than half its length => 2
2: Arista thickened to ca 2/3 the length. Distance between subapical bristles almost the same as between basal bristle and subapical bristle (see image above) => 3
#19
3: "Wangen" narrower than half the eye-diameter (see image above).
Scutellum with hairlike apical bristles (see image above).
Abdomen with discal bristles.
===> longicornis
Please comment if it seems a correct ID !

It is definitely Istochaeta and it looks like longicornis indeed.
Supposed to be nocturnal.
How did you get it ??
