Pale robber with black bands and circles on abdomen - Ablautus rufotibialis

Pale robber with black bands and circles on abdomen - Ablautus rufotibialis
Española, Rio Arriba County, New Mexico, USA
March 23, 2011
Size: 9-10 mm long
This has to be the end of my obsession with these things (except for a picture of one more individual). I'm hoping these angles, which I haven't gotten before, will allow an identification, but I'll try to get others if they'd help.

I was wondering why the two I photographed today were more cooperative than they usually are. For this one, maybe because it has prey? Is that an aphid?

Thanks for the identification. I've been trying to use a key by Wilcox from 1966 and mimus seems to be close, but it depends on too many things I can't tell from my photos or just don't know enough about.

Anyway, probably a number of pictures of this species are frass, so if an expert doesn't tell me what to keep within a few months or something, maybe I'll get rid of some.

 
Jerry -- I can't take this sp
Jerry -- I can't take this species beyond genus from the photos. Similar to mimus, except that sp. with thorax more brown and mystax black in lower third. Also, there are some new spp. known from N. Mex.

 
Thanks again.
I'll look for those points of difference from mimus. I hope I didn't sound like I was trying to nag you. One thing I learned from using that key was what identification characters I couldn't get in my photos.

It's interesting that new species are known. I had enough trouble with the key that I won't be surprised at all if this is one of them.

Yes, this is an Ablautus sp.

Can't help you much with the Robber, but that does, indeed, appear to be an aphid it's eating. :)

 
Thanks
One down, one to go :-)
