REMAINING (number with state)
Female, P. eickworti vs P. koso
 P. eickworti - The area of the propodeal triangle bordering the metanotum is strongly rugose, with lines running roughly longitudinal in the basal half - Pitting of T1 sparse medially, the average interpit distance variable but usually around three pit diameters or greater (1)
 P. koso - The basal half of the propodeal triangle bordering the metanotum is tessellate, with only weak patterning that makes the surface appear similar to sandpaper - Pitting of T1 closer, the average interpit distance usually equal to 1-2 pit diameters (1)
Female, P. parca vs P. zavortinki
 P. parca - The clypeus is relativfely evenly pitted throughout, if less dense apically then it is only a slight difference and there are still pits present in the area - The pitting of T1-3 is denser basally than apically, ranging from below one pit diameter to sometimes over one pit diameter, with the pits in the denser area usually slightly smaller than those that are more well-separated - The first recurrent vein meets the bottom of the second submarginal cell slightly before the end of the cell, usually by about 1-2 vein lengths (1)
 P. zavortinki - The apical third to half of the clypeus is almost entirely unpitted and shiny, at least medially - The pitting of T1-3 is about equally dense throughout, about one pit diameter, and although the pit size may vary throughout there does not seem to be a trend of smaller pits basally - The first recurrent vein meets the second transcubital vein linearly, right at the end of the second submarginal cell (1)
Female, abdomen, T2 and T3, hair density in middle of segment - Be careful, as hair loss here can become misleading
 As dense as is seen at the sides (3)
 Absent or nearly so, clearly less dense medially than at the sides (2)
Female, abdomen, integumental color
 Entirely black, without red (5)
 Noticeably reddened at least in part, but sometimes almost entirely so (2)
Female, rear leg, scopa, hair color
 Primarily light, if with any darker hairs then they are almost always limited to the top of the tibia near the basitibial plate (4)
 With significant amounts of both light and dark hairs, usually with the dark hairs near the basitibial plate reaching around the outer face of the tibia (2)
Male, S6, shape of the medial emargination - Caution, this is subtle and tricky without comparative material, be very careful with your diagnosis here
 Roundedly concave throughout (3)
 Roundedly concave for the most part, BUT the middle of the concave area is somewhat flattened with a slightly medial bump which is often hard to see (1)
 With a V-shaped concavity, which comes to a point medially (1)
Male, abdomen, S2-4, color of the medial patches of short, dense hair
 Lighter, whitish to very slightly off-white (3)
 Darker, brownish, sometimes a golden brown color and sometimes much darker (2)
Male, abdomen, S2-4, form of the medial patches of short, dense hair
 Thin, appearing linear, such that they are 2-3 times more latitudinally broad then they are longitudinally wide (4)
 Thick, often somewhat blob-like, such that they are less than twice as latitudinally broad as they are longitudinally wide (3)
Sex, number of antennal segments
 Female, 12 (5)
 Male, 13 (5)
State or province where bee was collected
 CA (10)
 NV (4)
 AZ (2)
