More commonly known as Ephydra hians. This is a common species in salt and alkaline lakes in the American West. Along with a few other species of Ephydra it thrives in lakes where little else can survive.

Thank you for adding your reaction John!

This fly I actually found at the shore of Paulina Lake, of which I don't know if it is salty.
I was also at Mono Lake, but I was too busy admiring the tufa's :)

I have another picture of it beneath.

Regards,
Hedy

The hairs under the fore basitarsus are a male secondary sexual character of Ephydra subgenus Hydropyrus.

I'd do anything for you John! ;)
I've summited this fly and also other USA flies, I hope Paul can use them for the gallery.

Thank you for all!

Hedy

Hydropyrus was synonymized with Cirrula by Mathis and Zatwarnicki in 1995.

I assume you mean in World Catalog of Shore Flies, which I don't have. Mathis' key in Manual of Central American Diptera (2009) keeps them separate.

I don't know the justification for either position.

Yes, the 1995 World Catalogue, though I also checked the latest 2016 version of that (which Wayne distributes to ephydrid workers) to ensure that it's still regarded as Cirrula. I think the fact that it appears in the Man.Cent.Am.Dipt. is simply that Wayne didn't update his key. It's not a genus I know (doesn't occur in the Palaearctic), so I have no opinion as to whether it should include Hydropyrus or not.

Please submit your North American flies to BugGuide too, at the general Diptera page http://bugguide.n...55/bgimage or on the family or species pages if you like.
