Hi
I would like some help in identifying this Chamaepsila sp. collected in Norway, Hordaland in June this year. I landed between Ch. pectoralis and Ch. strigata?

Head chaetotaxy: Verticals 3, postocellars 1, frontorbitals 2
Thorax: Dorsocentrals 2, notopleurals 1, scutellars 1, anepimeron bare.

I have more photos if necessary.

Looking at the photo given by Roháček (2012)) I really think you might have strigata.
Quoting from the paper:
Remarks: This is the most surprising finding of Psilidae in the Gemer area. The species was described from a series of specimens collected at Kolašin in Montenegro (Collin 1959) and apparently has not been recorded from elsewhere since the description. Its biology is unknown but the type locality is situated in a montane area (cca 1,000 m a.s.l.). The above female was swept from Carex tussocks on a swampy shore of a small pond (Fig. 5). The specimen perfectly agree with the original description. The species must be very close to Ch. pectoralis (Meigen, 1826), differing from the latter besides the striking dark upper band on the pleura only by somewhat shorter pilosity of the arista and longer ventral setulae on the fore basitarsus.
