Thread subject: Diptera.info :: Amobia?

Hello

In my searches I find Amobia, but the frons is almost bare.
I propose big photos for this family difficult to identify.
Thank you for help

What do you mean with 'the frons is nearly bare '

I clearly see a row of proclinate orbital setulae

Like Christophe, I can only see 2 proclinate orbitals 1 reclinate one and many frontals...:|

I agree with Stephane, not enough orbitals for Amobia. Furthermore, the side of thorax shows clearly no swelling in front of ampulla.

This must be a female of Oebalia cylindrica.

The shape of the head in lateral view seems to be a bit anomalistic: it looks as if antennae are inserted rather low. But that may be due to the fact that the head is turned a bit away.
A picture of the head in lateral and frontal view might solve the issue.

Clearly no Amobia. SOrry for my misinterpretation of the proclinate frontals.
Low antennae would suggest Metopodia, however, the parafacialia are much narrower in this case.
So it should be Oebalia cylindrica (note the small hairs on parafacialia)
