I key this specimen with some doubt to Blepharomyia angustifrons, could that be correct? 3 specimens in yellow pan trap, 12 April 2021, Renkum, Netherlands.

Thanks for any reply

That is very unlikely / hardly possible. Check for Phorocera (genitalia highly distinctive)

Thank you for your comment. I first also thought Phorocera, but I could not key to that genus as I could not see any hairs on the prosternum nor a shadowfold of vein M. I checked the drawings of Phorocera genitalia in Emden 1954, but I think/guess the genitalia do not match. Keying the specimens with Emden 1954 I end up with Blepharomyia pagana, maybe that is a better match than B. angustifrons.

I have added some extra photos of the wing venation, prosternum, genitalia and front and rear view of the head. I am not entirely sure if these photo are of the same specimen as the previous photos, but all 3 specimens look very similar and have the same wing venation and chaetotaxy on the head.

Hi Paul,

thanks for this effort. So we are making progress.
It is defintely not Blepharomyia nor Phorocera.

I am pretty sure it is the male of Lypha dubia.

Check the lappets on hind spiracle, difficult feature but highly distinctive !

Normally, you can ID this species even with binoculairs by its bronze colouration, but pan traps do not help here

Very common spring species.

Hi Theo,

Thank you for all your help. The feature of the lappets is not that visible on my photo's, but I think they agree with Lypha.
