Long-moushtached medium-sized brownish Robber with reddish spots on inflated legs; caught Leafhopper prey - Negasilus astutus - male

Long-moushtached medium-sized brownish Robber with reddish spots on inflated legs; caught Leafhopper prey - Negasilus astutus - Male
Madrona Marsh Preserve, Torrance, Los Angeles County, California, USA
May 26, 2011
Size: ~ 12 mm
Has the habitus of a big robber, but is relatively small.
Resembles Stenopogon, but wing veneration seems to indicate otherwise.
Keying it out didn't resolve it ...
If this is Stenopogon, could it be S. obscuriventris ?

Its prey appears to be Deltocephalus grex.

This is in the subfamily Asilinae. Actually, a new genus and species for BugGuide: Negasilus astutus. Congratulations Emile, nice find!

 
Fantastic ! - Thanks a lot, Eric !
Your expert contributions to this difficult family are much appreciated !

I saw that the range for Negasilus astutus extends from northern Mexico, through California, to Oregon.
Would you perhaps know if it is tied to a coastal, dune-like habitat, based on the records for this species ?

Thanks Emile -- you're most welcome! This fly is known from a variety of habitats: coastal, desert, montane, etc.; hard to characterize.

 
Thanks for your kind reply, Eric !
P.S. I checked the other Robber Fly photos I've taken from the same location and, among others, found this one: .
Albeit also brownish, they appear to be a different species.
Would you mind having a look at them ?
