The restricted markings of this black bee are cream to pale yellow. A. dammersi appears to be the desert counterpart of emarginatum. The differences between these two species are very slight, especially in the females. The median lobe of sternum VI of the male of A. dammersi is typically reddish-brown and has nearly parallel sides (fig. 38). Also, the apex of sternum VIII (fig. 39) is somewhat broader in dammersi than in emarginatum. For the females, the more convex tergum VI (in profile) and the lack of maculations will distinguish dammersi. The pronotal lobe is black in dammersi, usually yellow in emarginatum. Also, the southern California populations of emarginatum have a yellow clypeus in the female, whereas the clypeus is nearly all black in dammersi. The distribution of this infrequently collected species (27 3,17 9 ) is almost completely in the Colorado and Mojave deserts. No sympatry with emarginatum is known, since in southern California emarginatum is found in mountainous and coastal areas. The few host associations are from the leguminose genera Astragalus and Dalea; or Phacelia of the Hydrophyllaceae.
