REMAINING (number with state)
Female, head, mandibles, integumental color
 Light, white to pale amber, obviously much lighter than the mandible tips (2)
 Dark, a brownish color similar to the mandible tip, although it may seem slightly more reddened basally (1)
Females, A. apiformis vs A. sejunctus - WARNING, very hard to tell apart, use positively identified reference material if possible
 A. apiformis - Labrum with a central slightly raised unpitted line running longitudinally along its surface, this line sometimes infringed upon slightly by a few pits - In direct comparison, there are fewer white hairs just after the basitibial plate on the hind tibia - This species is only known in the US from TX (1)
 A. sejunctus - Labrum bumpy throughout, if with any longitudinal line at the middle then it is VERY weak and most often almost completely obscured by pits - In direct comparison, there are more white hairs just after the basitibial plate on the hind tibia - The range of this species includes AZ, CO, TX, and likely NM (1)
Locality where specimen was collected in USA
 NM (6)
 TX (6)
 AZ (4)
 CO (2)
Male, abdomen, S6, form of emargination or concave area in the middle of the rim
 U-shaped - The medial emargination is smoothly rounded throughout, the sides concavely coming together to the center Sides overall forming an acute angle (1)
 V-shaped - With a distinct medial point where the two sides meet at an acute angle such that the emargination is not evenly curved throughout, with the sides convexly coming to the medial point Sides overall forming an acute angle (1)
 Very broad and shallow The middle is relatively indistinct and only slightly shorter than at the sides Sides overall forming an obtuse angle (1)
Sex number of antennal segments
 Female 12 (3)
 Male 13 (3)
