Yes, definitely Ulidiidae. Near
Melieria and especially
Tetanops, but not a species I've seen before.
#5
hmm... I have photos of the male, I think.
I will show them very soon.
it is rather different from the other Ulidiidae I used to see in Silgueiros.
#6
male, I think...
this fly was very near in relation to the female I showed you before.
The fly is above Ammophila arenaria.
Both have black tergites as you can see.
#7
hmm... with these photos is it possible to say more about possible species?
#8
It's
Tetanops alright:
Tetanops myopina.
Never realised the male has a black abdomen, but I checked my collection and it's indeed true.

Hi Jorge,
Hmm... in that case I would like to reconsider my ID.
I see that T. flavescens has been recorded.
Looking at my specimens, and beyond the black abdomen, the frons is not as long as a typical T. myopina, nor have your specimens the clear black spots in which the setae are placed on the thorax. I mistaken the small black dots on your picture, which are actually the setae themselves, for the black dots on the thorax. Looking at my specimens I see they should be bigger than in your photo.
So sorry I'll have to correct my ID to Tetanops falvescens.
Lo siento
John

ok.
In Portuguese is: Sinto muito. Lo siento is Spanish.
