Hello,

my pictures are from June 27 near the village of Bantikow, Brandenburg, Germany.
Is an ID possible? With Zodion I am pretty sure - but which one?

Thank you for an answer!

Hans

Hello,

hopefully someone could possibly confirm Zodion sp.

Cheers, Hans

I think it is Thecophora (male).

Geetings,

Henrik

Hi Hans
I think you were correct in calling it Zodion based on the fact that the proboscis is bent at the base. Thecophora would have a bend in the middle resulting in the proboscis being much shorter when folded. You can see photos of both in the gallery: Zodion, Thecophora.
Other than that, the two genera are pretty similar to my eye.

Regards
Steve

No, proboscis is bent twice, as can be clearly seen in the first picture, so it is Thecophora.
See the key here:

Another opinion Wink

I absolutely agree with Henrik, it is Thecophora, no shadow of doubt. Apart from the proboscis (as said by him, first picture is clear) genae are smaller in Thecophora than in Zodion, which gives a very different look at the face when seen in profile view.

Hi Henrik and Piluca,
Thanks for the correction and the link to the key. I was confused by fact that the first segment of the proboscis is so long and have never seen a Thecophora (photo or fly) like that – all of the descriptions I've seen of that genus put the bend in the "middle" of the proboscis. I also misremembered how many bends each genus had

Regards
Steve

Hello Steve, Piluca and Henrik,

thank you so much for your interesting discussion!
Following the key I think it is a member of the atra-group, isn't it?

Best regards,
Hans

I think so too, and likely to be T. atra itself, which is the most common sp in Central Europe anyway

Regards,
Henrik.

Hi, Steve and Hans Smile

I am glad the discussion was of any help Smile Wink

And yes, it is of the atra-group Smile But males are hopeless, very hard even with the specimen in hand, as far as I know Sad
