Small metallic-green Fly with black face and pale tarsi on Manroot - Lamprolonchaea - female

Small metallic-green Fly with black face and pale tarsi on Manroot - Lamprolonchaea - Female
Palos Verdes Peninsula, Los Angeles County, California, USA
October 24, 2015
Size: ~ 3 mm
Found inspecting exposed root of Marah macrocarpus (Cucamonga Man-root) with no obvious sprouts or tendrils attached to it.
Is this a female Lonchaeid Fly in genus Lamprolonchaea ?
If so, it would be the first record for the U.S.
The genus is mostly found in Oceania and one species from Africa.
They have the potential to become a pest species on tomatoes and other fruits.

Tentatively Lamprolonchaea
I consulted an expert and except for location it is clearly a Lamprolonchaea. If you can get a male to Martin he should be able to identify species. There are at least three candidates, plus dozens more without a history of accidental transport.

 
Thanks for the confirmation & upward mobility, John !
L. smaragdi might be our primary candidate, followed by L. brouniana.

I'll keep two eyes out for them.

Moved from ID Request. Family looks good.

This could be a very important find. John made me aware of it. Do you have a specimen? It would be very important to collect some specimens, because as John mentioned, they can not be identified by pictures alone. So if you have some or can re-sample them, please send them to:

Thanks for your feedback, John & Martin !
If you can corroborate that this is indeed a Lonchaeid, it should belong in genus Lamprolonchaea, as it is my understanding that this is the only Lonchaeid genus with metallic-green flies.

And yes, I didn't realize until later that this was a potential pest species.
I'll try to capture specimens and send them to you.

 
Dear Emile, I have now specim
Dear Emile, I have now specimens of this species which Jim collected in LA and we are writing a note about this species, because it is new to North America. We would like to add you finds to the paper and would like to ask you for the exact location and date and for your full name, so we can acknowledge you. You can email me that info to my personal email. Thanks so much,
Martin

 
Thanks, looking forward to se
Thanks, looking forward to see these flies under my microscope...

Maybe
Lamprolonchaea is plausible, but I consider genera of Lonchaeidae to be unidentifiable from photos. Let me see if I can get an expert opinion...
