I have spent some time lookin

I have spent some time looking at pictures and the thin pale central stripe and the pair of pale stripes broader at the posterior end seems to be significant. I don`t know how variable this species is. The differences I mentioned below may just be a trick of the light and having looked at your images recently placed in Helophina, I am now thinking you are right and these are Parhelophilus rex.
Good work by you. I will send all the images and comments to Dr Martin Hauser.

I think the mating pair are H

I think the mating pair are Helophilus rex.
Note the upper occiput has a bloom with a clear triangular shape at centre. Also note the upper occiput is somewhat inflated. Note the humeral callus area is very orange. Note the scutellum has any black restricted
These features look different in this specimen.

OK, fair enough.

I am going to post some more pics some other individuals seen on the same day which more clearly show the metatibial feature in question. I will post them to Helophilina for the time being.

The hind tibia is similar in

The hind tibia is similar in many species of Parhelophilus and Lejops but if the image is good then on structural differences maybe we can separate them.

I've sent some time looking a

I've sent some time looking at reliable pictures by Steven Falk of Anasimyia lunulata = Lejops lunulatus. I think this is very likely Anasimyia lunulata and a male, not a female as I first thought. It is safe in Lejops, subgenus Anasimyia and that is where it should stay.

Many thanks Bill, Martin and Ken!

I will get better pics this summer, I hope :)

Based on features I see in the draft Syrphidae of NE

I believe this is Parhelophilus rex

Thanks Bill!

I suppose it is impossible to narrow to some species? I will post the other individual.

I am only confident to Lejops

I am only confident to Lejops, subgenus Anasimyia but post other pics as they may be helpful.
