Chaitophorus

Starting at the Chaitophorus on willow key since I am quite confident of that genus:

http://www.aphidsonworldsplants.info/C_HOSTS_Sab_San.htm#Chaitophorus

1. I don't see a constriction, 2.
2. PT/base = 2.4, Antenna base has 2 accessory hairs, R IV has I think 3 accessory hairs, certainly not 11, 3.
3. This one would probably be easy with good images of C. pustulatus but it appears the answer is that it does not have numerous small rounded nodules, 4.
4. The hind femora is much darker than the tergum. I only see 3 accessory hairs on R IV, dorsal pigmentation might be called uniform but it is difficult to tell, I believe the color is mostly three embryos. It does seem awfully close to C. utahensis but does not seem to be a perfect match.

From that keying out it really does appear that this is either C. pustulatus, C. utahensis or an undescribed species. At the moment I am leaning undescribed species but the only thing I see keeping it from being a good match for C. utahensis is a couple hairs on the R IV. It was also found on leaves when C. utahensis has previously been reported on bark. I cannot find any photos online so this is probably a dead end unless I find someone who has access to specimens of these two species to compare to.

Here is another reference of interest:

If you're confident of the genus..

...then you should move the images there. It's fine to post at your lowest level of certainty. ID Request is for folks who have no idea of what they've got.

Lost

I can do that? How?

Bugguide UI has always had me lost. I don't see any buttons to move the entry to a new species and always figured I didn't have approval from the site to move things around.

You can post anywhere in the Guide...

...and you can always move your own images.

To post in the Guide, navigate to the appropriate taxon (i.e., Aphididae), make sure you're on the Images tab, then click on the "add image" link. Complete the submission form and upload the pics--just as you would in ID Request.

To move your pics, click on "tag all" beneath one of the images. Thumbnails will appear at the upper left of the page, above the Clickable Guide. Then, navigate to the appropriate taxon, make sure you're on the Images tab, and click the "move tagged images" link.

If I haven't made things clear, just let me know.

Thanks!

Thanks! I never would have figured that one out on my own.

What about species not already in the guide?

These ones here are Macrosiphum salviae which as far as I can tell is not included in bugguide:

You can request a new page...

...in the "Requests for Additional Guide Pages" forum. However, most editors will want to see an expert ID before creating a new page.
