Several on mud among Spartina at back of salt marsh. Other flies from the marsh:

Dimecoenia spinosa (Loew)
Moved from Dimecoenia. ID'd from specimen, now a photo-voucher. Thanks Aaron.

New species/genus for the guide. Also look for Cirrula gigantea in similar habitat on algal mats; it's quite large, up to 8.5 mm.

Does it look similar?
I'm pretty sure I saw a few last year, but I never managed to capture one.

It should
It should look similar to this or the Cirrula in the guide. A large chunky ephydrid I suppose. More information on these two genera can be found in (1)

Two large chunky ephydrids
I went back to the same location today and found two similar ephydrids, one substantially larger than the other. Look about right?

way to go!
I'm pretty sure that's it, with the long setae on the face it definitely looks like Cirrula

Moved from Ephydrinae.

Moved from Flies.
