Female, A. apicale vs A. azteca vs. toltecum
 A. apicale - pits on T1-2 smaller than those on scutum and extemely dense - T3-5 with solid yellow stripes - with long hairs on scutum - Scutellum not appearing inflated or only slightly (1)
 A. azteca - pits on T1-2 subequal to those on scutum - T3-5 with black spots in one or all yellow stripes - with short hairs on scutum - Scutellum not appearing inflated or only slightly (1)
 A. toltecum - pits on T1-2 subequal to those on scutum - T3-5 with or without black sponts on yellow stripes - with long hairs on scutum - Scutellum appearing inflated (1)
Female, A. ehrhorni vs All others
 Others - Rim of the clypeus normal like other species and the clypeal apex projects less than 1 ocelli diameter out from the labrum - The center of the rim of T6 is concave or emarginate, although not as extreme as in A. ehrhorni, and the rim of T6,after the emargination, while angled, transitions smoothly without a point, sharp corner or projection with the rest of the rim of the segment (3)
 A. ehrhorni - Clypeus unusual in that the rim projects much farther forward over the mandibles than the other species, if you look at it from the side you will see that the apex of the clypeus is well over 1 ocelli diameter out from the labrum - The center of the rim of T6 is concave or emarginated, on either side of that emargination are two small projections or teeth forming sharp clear points (1)
Female, A. eiseni vs A. notatum robertsoni
 A. eiseni - Omaulus less concave (1)
 A. notatum robertsoni - Omaulus more concave (1)
Female, A. xilitlense vs Others
 Others - females available for guide building (14)
 A. xilitlense - no females seen (1)
Female, abdomen, T5, shape of apical end
 Median extension 1/2 as wide as segment width, shallowly concave NOT forming two strong angles medially but WITH two lateral angles (13)
 Median extension 1/3 as wide as segment width, deeply angled inward forming two strong projecting angles medially (1)
Female, leg, hind tibia
 Yellowish-red WITHOUT black (5)
 All BLACK (4)
 Yellow WITH black (2)
Females, abdomen, S6
 Last sternite apically only covered with very short scopal hairs WITHOUT spine-like projections (11)
 Last sternite densely covered with pale scopal hairs and at the apical sides WITH hidden slender reddish orange spine-like projections, these are as long as the scopal hairs (1)
Females, mandibles
 With 4 clear teeth (11)
 Only with a clear apical and subapical tooth (1)
Head, Paraocular region
 Yellow maculation short, ending at antennal sutures (14)
 Yellow maculations shortER, ending below antennal sutures (6)
 RED maculation extra long, ending near top of compound eye (2)
 Yellow maculation long, ending above antennal sutures (2)
 RED maculation long, ending above antennal sutures but no where near the top of the compound eye (1)
Head, clypeus, color
 Entirely yellow or red, or with black only in part (19)
 Entirely black (12)
Head, sculpting on the two small swollen areas found directly between the lateral ocelli
 Largely unpitted, may be a few invading the edges (14)
 With pits throughout, at approximately the same density as elsewhere (12)
 With very coarse pits throughout (5)
Male, A. apicale vs A. azteca
 A. apicale - yellow stripes on T3-5 solid without black spots on one or all terga, T6 with medial red area - Apical end of T7 NOT bent over - S6, if visible with deep depression but adjacent mounds low (1)
 A. azteca - yellow stripes on T3-5 with black spots on one or all terga, T6 with medial black mark - Apical end of T7 bent over - S6, if visible, with deep depression creating two large mounds or peaks (1)
Male, A. eiseni vs A. notatum robersoni vs A. notatum gilense
 A. eiseni - T7 lacking apical fringe of hairs - Midtibial less pitted - Omaulus less concave - hind tibia black and yellow - Yellow maculations on T2 thinner by comparison with A. notatum robertsoni (1)
 A. notatum gilense - T7 with apical fringe hairs LONG - Midtibia relatively more pitted - Omaulus not very concave - hind tibia yellowish-red - Yellow maculations on T2 thicker, like A. notatum robertsoni (1)
 A. notatum robertsoni - T7 with apical fringe of short hairs - Midtibia usually relatively more pitted - Omaulus more concave such that the edge has folded outward at the curve - hind tibia black and yellow - Yellow maculations on T2 thicker in comparison with A. eiseni (1)
Male, abdomen, T7, overall shape of the apical rim
 Broadly rounded, with a concave area in the center (7)
 Rim triangular in outline, coming to a blunt point , never with a concave area in the center (6)
 4 teeth on rim separated by three concave areas (1)
 Broadly rounded, with a wide notch in the center (1)
Males, abdomen, S6
 WITHOUT spine-like projection (13)
 WITH a central, long, spine-like projection EXTENDING as far as the tip of T7 (1)
