Hi,
This evening I saw a couple of Miltogramminae - can it be named? And is the upper one really the male, being that fat and having a broader frons than the lower one? Thanks for any explanation,
Sundew

Hi,

Difficult to tell from these pictures, which are very nice but don't go into enough detail. Might by Pterella grisea, but don't quote me on it ;)

Thanks for the guess! I am looking forward to Liekele's opinion.

Indeed very very nice pictures.

Assuming you made these pictures near Berlin, Pterella would be a very nice finding.

But I do not agree on Pterella for several reasons.
The male has rather big claws.
On vertex I do not see any hairs next to the bristles.
On notopleuron I do not see any hairs next to the notopleural bristles.
Tegula seems to be black.
Basic colour of frontal stripe should be yellow in Pterella but is black.

Therefore I think this is a couple of Senotainia albifrons.

Btw: Frons is indeed in male often broader than in female in Pterella as well as in Senotainia.

Many thanks for all the explanations! I add some detail magnifications of the parts mentioned; maybe, the ID thus becomes more certain. The frontal stripe of the female is brown, the male's is black. Jari's Senotainia albifrons seems to have longer bristles and hairs (http://www.dipter...d_id=31141), mine "shows more skin". Nevertheless I would add the couple to the gallery under S. albifrons, or should it better be with "cf."?

Leikele, you have convinced me. I had excluded Senotainia becuase the claws didn't seem long enough to me and the pictures weren't clear enough to make out notopleural hairs. From sundew's extra pics it is clear that there are no hairs.

Many thanks to both of you! Thus no "cf." needed.
