I just received a copy of this paper (1)
yesterday. It more than doubles the number of described hackberry gall midge species, and I just finished IDing all the BugGuide photos
as best I can. We have ten of the 23 species in the guide, and a couple of others are shown in my blog post here
. As I sorted through the photos it was fun to see that some of them depict specimens that are listed in the species descriptions. MJ Hatfield, Mark Fox, Ilona Loser, John Pearson, Joe Zito, and myself are listed in the acknowledgments.
