REMAINING (number with state)
A. abroniae vs A. columbariae
 A. abroniae - T5-6 appearing lighter due to pale hairs spread over its surface - The indent at the middle of T7 between the two projections is clearly concavely curved inward throughout such that it appears U-shaped - The two projections found medially on the rim of T7 are more widely separated (1)
 A. columbariae - T5-6 appearing darker due to many brownish hairs spread over its surface - The medial indent on the rim of T7 is more angular, slightly V-shaped as a result - The area between the two projections found medially on T7 is narrower than in A. abroniae (1)
A. albata vs A. flexipes - Note that these are potentially the same species
 A. albata - All the hairs on the clypeus or paraocular areas, near the ocelli and on the vertex are the same color, a very plain white - According to Cockerell 1906, the eyes are yellow and the apicomedial pair of projections on T7 are shorter and more parallel, although this is not consistently apparent to the author of this key (1)
 A. flexipes - The hairs on the clypeus and paraocular areas are a different color than those found near the ocelli and vertex, with the former having plainly white hairs and the latter having off-white to yellowish hairs - According to Cockerell 1906, the eyes are green and the apicomedial pair of projections on T7 are longer and more divergent at the tips, although this is not consistently apparent to the author of this key (1)
A. columbariae vs A. salazariae - A dissection will likely be necessary
 A. columbariae - On S8 there is an apicomedial projection to the sides of which lobes are found, each of these lobes curving concavely inward as you travel laterally from the apicomedial projection BUT THEN they curve outward once more such that there appears to be a semi-circular indent between the apicomedial projection and the lobe - The lateral corners of the apicomedial projection of S7 are rounded, not coming to apical points - The hairs on T5-6 are largely dark brown or black such that they appear more dark overall regardless of the angle at which the bee is viewed (1)
 A. salazariae - On S8 there is an apicomedial projection to the sides of which lobes are found, these lobes curving concavely inward as you travel laterally from the apicomedial projection, before eventually leveling off at the tip of the lobe such that there appears to be only a very broad and shallow indent between the apicomedial projection and lobe if any - The lateral corners of the apicomedial projection of S7 are acutely pointed - The hairs on T5-6 are largely pale, somewhat tan, although these terga appear slightly darker than the preceding terga due to the lack of appressed, pale hairs, note that sometimes these light hairs only appear as such from certain angles (1)
A. lesquerellae vs A. ursina
 A. lesquerellae - The rear edge of the mid basitarsus is fringed with very long, INTERMIXED black and white hairs - On the outer face of the tarsal segments of the mid leg there are white hairs - The fan present on the last tarsal segment of the mid leg is, in comparison, more well-developed, usually at least tripling the width of the tarsal segment - In direct comparison, usually smaller than A. ursina (1)
 A. ursina - The entire rear edge of the mid basitarsus is fringed with very long LIGHT, whitish hairs only - On the outer face of the tarsal segments of the mid leg there are long, prominent orangish hairs - The fan present on the last tarsal segment of the mid leg is only weakly developed, often not even doubling the width of the segment - In direct comparison, usually larger than A. lesquerellae (1)
A. lesquerellae vs A. vannigera
 A. lesquerellae - The width of the labrum is only slightly less along the rim than at the base, clearly more than half its width - The rim of the labrum outside of the yellow center is a solid black color (1)
 A. vannigera - The width of the labrum is significantly less along the apical rim than at the base, usually about half or less - The rim of the labrum outside of the yellow center is a somewhat transparent orangish-brown color (1)
A. pacifica vs A. porterae - Note that these are both large, robust members of the subgenus Lophanthophora which are most distinctive for the black running base-to-apex on the sides of the clypeus combined with the usual presence of a great deal of black hairs on the outer face of the mid tibia, although in some specimens of A. porterae this black hair may be extremely limited - Note that in both species the hairs of the abdomen may range from slightly off-white to light brown
 A. pacifica - The hairs of T1 are always primarily light and there are ALWAYS at least several blackish hairs present near the rim, often more dense medially, although sometimes these hairs may be shorter than the surrounding pale hairs and hard to see as a result - The outer face of the mid tibia is much darker in terms of overall hair color, the prominent white patch of hair being limited to the apical half of the tibia on the posterior edge although uncommonly the light hairs may extend WEAKLY toward the base along the posterior edge of the outer face OR sometimes at the very apex the white hairs may reach into the anterior side of the outer face - T2 is more variable in hair color proportions, ranging from primarily light as in A. porterae to primarily dark, the length of the black hairs USUALLY equal to that of the lighter hairs at least in part - In general, this species is usually slightly smaller than A. porterae in direct comparison (1)
 A. porterae - The hair of T1 is ALWAYS all pale, lacking any blackish hairs - The outer face of the mid tibia is USUALLY much lighter and the white hair along the posterior edge of the mid tibia extends all the way from base to apex in all specimens the author has observed, although there are specimens ranging from primarily light to almost entirely dark hairs anterior to this posterior patch of white hairs - T2 is ALWAYS primarily light, sometimes even appearing all pale in a cursory inspection, usually with the vast majority of the present black hairs being short and harder to see although sometimes there may be some dark hairs about equal in length to the light hairs - In general, this species is usually slightly larger than A. pacifica in direct comparison (1)

 Present - with an apical hair band that clearly contrast in color with the hairs of the hairs basal region or, in some cases, there may be no OBVIOUS hairs along the base because they are dark and extremely short and thin (18)
 Absent - BUT appearing present due to the underlying integument along the rim being CLEAR, upon inspection you will see that the hairs along the rim are about the same color and density as those at the base, BUT appearing to have a band nonetheless due to the integument of the apical rim being clear (14)

Subgenus Heliophila - Abdomen, T6, presence of a flange or upturned ridge found laterally on each side, DO NOT score if there are simply rounded or smooth bumps present - Be careful as sometimes they may be hidden beneath the rim of T5
 Present (13)
 Absent (9)
Subgenus Heliophila - Abdomen, T7, longitudinal ridge running to the apex medially - Note that the ridge may not run all the way to the base
 Absent (16)
 Present (7)
Subgenus Heliophila - Mid leg, length
 1. Normal - When the leg is held up and folded downward at the joint of the femur and tibia such that the tip of the leg is directed posteriorly, the tip often reaches back to some point before the tip of the abdomen but never all the way to the tip (50)
 2. Extremely long - When the leg is held up and folded downward at the joint of the femur and tibia such that the tip of the leg is directed posteriorly, the tip fully reaches or surpasses the tip of the abdomen (3)
Subgenus Heliophila vs other subgenera - Fore wing, first submarginal cell, presence or absence of hairs - Make sure to view the wing from both sides
 Other subgenera - Present (34)
 Heliophila - Absent, note that some male A. squammulosa from Jalisco, Mexico have been seen to have hairs in the first submarginal cell (20)
Subgenus Mystacanthophora - Abdomen, S5, form and number of hair tufts at the middle near the rim - Be careful, matted or missing hairs can be extremely misleading here
 Four distinct tufts of roughly equal size - Two medial and one to either side of them (1)
 No tufts - S5 is covered in short white hairs of roughly even length throughout (1)
 Three distinct tufts - One large medial tuft and one to each side (1)
 Two distinct tufts - Two elongate tufts which appear indented basally and can be mistaken for four tufts if not careful (1)
Subgenus Paramegilla - A. centriformis vs A. fulvicauda
 A. centriformis - The base of the mandible has a GREATER area of light integumental color extending all the way to the impressed lower rim of the mandible - The hind basitarsus is densely hairy at the interior of its apex, with no sign of an integumental spike directed distally - The apical hair bands on the terga are thinner, to the point that they may sometimes be hard to see with the naked eye - In direct comparison, this species is usually larger than A. fulvicauda (1)
 A. fulvicauda - The base of the mandible has a LESSER amount of light integumental color, this color ending BEFORE the impressed lower rim of the mandible - The apex of the hind basitarsus is less densely hairy, with a small spike directed distally from which several spiky hairs often arise - The apical hair bands of the terga are thicker, often taking up to a fourth of the length of the tergites - In direct comparison, this species is usually smaller than A. centriformis (1)
Thorax, mesepisternum, hair color
 1. All light - White to off-white or yellowish to orangish (44)
 2. With light hairs present PRIMARILY, but with a VERY SMALL number of darker hairs present near the top of the mesepisternum which are usually easily overlooked (10)
 3. With both light and dark hairs present in appreciable numbers, but the dark hairs are USUALLY limited to the TOP HALF (7)
 4. With both light and dark hairs present in appreciable numbers, the dark hairs restricted to the bottom and the light hairs on top (1)
Thorax, scutum, hair color
 1. All light - Whitish to yellowish or VERY light brownish orange (26)
 3. A MIXTURE of light and dark hairs - With the presence of both colors readily apparent throughout all or most of the scutum (24)
 2. Primarily light - Whitish or yellowish, but with some very small number of darker hairs which may be easily overlooked if not careful, these limited dark hairs often ONLY found medially so the rims of the scutum appear only lightly haired (23)
Thorax, tegulae, integumental color - Ignore hair color
 Dark brownish to black - Usually entirely opaque or nearly so (36)
 Light tan to slightly brown - Usually clearly transparent (34)
