Hi,
This is an Asilid from Austria, Tyrol, Niederthai (1.500 m) seen in last August. A comparison with the gallery led me to
Choerades gilva; I need experts' help, however.
Many thanks, Sundew

It could be but the back of that species is red, which is sometimes hard to see because of the wings folded as in this case. I dont see any sign of red..... Maybe Andrenosoma atrum is an option. Can anyone tell me the difference between Andrenosoma and Choerades. It should be something with the antennae.

Hi Leptogaster,
The most noticeable difference between Andrenosoma & allies (Andrenosomatini) and the Laphriini group (Laphria, Choerades, Lampria, etc.) is the shape of the proboscis. The latter have a long, straight, thin (laterally compressed) proboscis -- which Oldroyd said "looks like a butter-knife." Andrenosoma have a shorter, tapered, dorsoventrally flattened proboscis which sometimes is pointed & upturned at the apex.
This "black asilid" is one of the all-black Choerades (not gilva, I think).
Regards,
Eric

OK, let's say
Choerades spec. then! I can't see a red back either. And the proboscis seems to be laterally compressed. I'll keep that character in mind. Many thanks to both of you!

Eric thanks for the explanation, maybe you can have a look at my Neoitamus problem?

Leptogaster, I looked at your Neoitamus socius "problem" (the Netherlands specimen photo). I agree that It does seem to be that species (for example, it has the bulging hypandrium, with long setae). However, as I am by no means an expert on Palaearctic Asilinae, I am reluctant to make a positive confirmation from the photo: you should have Dysmachus or Danny, or some other expert on European Asilinae make a confirmation.
Regards,
Eric

Is the specimen saved in a collection?
#8
The Neoitamus has not been collected.

Sorry, I asked for the Laphriinae of this thread -
Neoitamus was another story
#10
I thought so, but just to be sure again.
