Pseudopanurgus compositarum (Robertson, 1893)
male; A new (but expected) state record for Arkansas. I'll double check the ID when I return to the AMNH and have access to specimens.

Compare the face pattern to the illustration in Mitchell (1960), available at the discoverlife species page for P. compositarum. In both the photo and Mitchell's drawing you can see that the outer subantennal suture typical of andrenids is incomplete in compositarum males.

Note that this is a species of Pterosarus Timberlake, often placed as a subgenus of Heterosarus (MMD 1994) or Protandrena (Michener, 2000).

Thank you for posting photos of such interesting AR Hymenoptera.

MMD 1994?
What is MMD?

Pseudopanurgus compositarum
i should be thanking you for identifying all of these Hymenoptera i do enjoy so, and for the information on any bee i post, as i really know very little about anything Apoidea.

I thank you
for being the first to photograph this species

and the first to document it in Arkansas
