Pheidole creightoni major worker, California
After reading a couple times through Corrie Moreau's hot-off-the-press Pheidole evolution paper, I am pleased to give it a thumbs-up. The paper is behind a subscription barrier, so I have distilled the results into an informal summary:
My earlier list of the most-studied ant species contained a few omissions.Â Here is a more inclusive list:

Out today is a preprint version (subscription only) of Corrie Moreau's Pheidole phylogeny. At first glance this seems a nice piece of work: the evolutionary history of one of the world's most diverse ant genera inferred from 140 species and 5 genes.
This is some extremely cool ant evolution…
