Thread subject: Diptera.info :: Bithia? Tachinidae central France

Dear all,

Here is a Tachnid question.
Specimen is from central France (loire atlantique, dry habitat).
Following central key, I endend on Bithia (B modesta if I try to go to species identification)
But I must be wrong, has the front is much narrower than should be and arista has no hairs.
So a little help to go further?
I am not totaly sure it is not a Rhinophoridae, subscutellum is totally hidden (but there is no petiole on wing)

Best wishes,
clovis

Such a narrow frons is acceptable for Bithia immaculata.

Sorry, I could not access my speciemens before.

Many thanks for your help Theo!

I ruled out B immaculata because of the abdominal line I see on this angle. But maybe it is to moderate to take account of?

Yes, no imma ulata but it does looks like Bithia.
I am on the road now. Check Peter Tschorsnigs key (online available in English at Chris Raper's) website. One has a hooked syncercus, yhe other has not.

Tschorsnigs'key is the "central european key"?
I was unable to find another key.

Using it, I'd stay on B modesta: syncercus straight, frons 0,59-0,8 wide one eye.
Do you agree?

Many thanks foryou help :)
Good travelling (possible in you country? luky you!)

Yes, the central European one.

As for Covid, it seems we have a "Dont ask, dont tell" policy...
