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.
