The Coccinellidae (Coleoptera) of America North of Mexico
By Robert D. Gordon
Journal of the New York Entomological Society, Vol. 93, No. 1, 1985
ISBN: 0934454922
Cite: 48287 with citation markup [cite:48287]
912 pages

Slightly dated with regard to status of imported species (1985 - Harmonia axyridis establishment listed as questionable - oh, were it true!), but still a great comprehensive work covering all of lower 48, with detailed line drawings, keys to all species, and distribution maps.

[Thanks to "Jason W" for recently posting news of this in the forums!]

It's been some time since I've used this, but as I recall it isn't complete - he refers to some of his smaller monographs for groups not covered.

"Keys to all taxa"
You would certainly know better than I, but the Abstract states: "The 57 genera and 475 species of Coccinellidae occurring in Am. north of Mex. are treated taxonomically. Keys to all taxa, descriptions of the higher taxa, species diagnoses, synonymies, and host records are included."

Mainly, I just wanted to get a record of this work into the Guide, so I could reference it. Please modify the post as you see fit.

"modify the post"
Editors can't modify your post; only you can do that. Including the publication date would be helpful, especially since you say "Slightly dated..." Exactly how dated is it?

At the bottom of this page you commented "1) The dominate subspecies, C. m. lengi..." but I assume you meant "nominate subspecies". If that's so, wouldn't the nominate subspecies get its name from the specific epithet, and therefore be C. maculata maculata?

I'd like to transfer the contents of your comment to the species page, and have already copied the text to a local file for temporary storage (if I edited the page without doing this, your comment would disappear).

I added the pub date to the book post.

I'm not sure what the correct adjective is for the subspecies, but what I was trying to indicate was the color form which is most widespread and common (as far as I can tell from Gordon's writeup). Perhaps "predominate" is a better word? But if "nominate" is more appropriate, please change the text.

(the Info pages seemed simpler when I could just post a comment and have it remain there :( But thanks for not "deleting" this comment as many others have been recently.


I changed it
to "most widespread" and updated the page with your comment.

New pages
I created the pages for Brumoides septentrionis and added your comments as best I could. It is true that it was easier to add comments to info pages before, but some people added completely irrelevant material, so it is better this way. Also, John created a new forum section for that purpose.
I have been going through some info pages and transfering the comments when appropriate so they don't get lost, but we have so many pages. . .
Thanks for all your help.

but you are still correct, Phillip
while the abstract technically isn't incorrect, upon further review at least the detailed description of several genera are in an older work. see The Scymnini (Coleoptera: Coccinellidae) of the United States & Canada: Key to genera and revision of Scymnus, Nephus, & Diomus(1)
