REMAINING (number with state)
Female, P. michelbacherorum vs. P. utahensis
P. michelbacherorum - Thorax, pronotal lobe and mesepisternum, hair color, ALL PALE - Head, clypeus, usually with a YELLOWISH SMUDGE along the rim - Abdomen, pygidial plate, with a slightly raised central area that forms a low longitudinal hill or mound that disrupts the curve of the overall plate, the flattened hairs to the outside of this mound has clear silver reflections, in direct comparison with P. utahensis the plate is slightly smaller (1)
P. utahensis - Thorax, pronotal lobe, hair color, usually a mix of LIGHT AND DARK hairs but some all light haired individuals exist, these dark hairs extend beneath the wing on the upperside of the mesepisternum and occur scattered amidst the light hairs - Head, clypeus, color, ALL DARK - Abdomen, pygidial plate, in direct comparison with P. michelbacherorum, larger, the surface is bowed very slightly across the segment forming a uniform shallow arc as in a warrior s shield (1)
Female, abdomen, T2, latitudinal white hair bands
1 hair band ONLY, located only along the base of the segment, sometimes T1 overlaps T2 and the band is only visible laterally (3)
2 hair bands one along the base of the segment which is sometimes hidden by T2 in the middle and one subapically, set back a small distance from the rim and this one is sometimes incomplete in the center (3)
Female, abdomen, T2, rim
Unpitted portion of rim NARROW, less than the width of F2 (4)
Unpitted portion of rim WIDE, equal to or more than the width of F2 (3)
Female, head, vertex, hair color
Mix of black and yellow hairs (4)
All yellow hairs (3)
Female, mid leg, tarsal claw length
Inner claw is more than half the length of outer claw (4)
Inner claw is less than half the length of outer claw (3)
Male, P. limitaris vs. P. pruinosa
P. limitaris - Head, clypeus, color, BLACK - Vertex, back of the head, with a row of DARK HAIRS intermixed among the long pale hairs - Thorax, mesepisternum, hair color, a MIX of dark and light - Abdomen, T7 pygidial plate apical margin, more rounded than angular - In direct comparison with P. pruinosa, T2 hair bands are narrower (1)
P. pruinosa - Head, clypeus, color, usually with apical HALF YELLOW, occasionally reduced to a small yellow mark or entirely black - If clypeus is all black, then inspect the long hairs at the back of the head these should be all yellow except for those directly behind the ocelli which can have a few dark hairs intermixed - Thorax, mesepisternum, hair color, ALL LIGHT - Abdomen, T7 apical margin, ANGULAR - In direct comparison with P. limitaris, the T2 hair bands are wider (1)
Male, P. michelbacherorum vs. P. utahensis
P. michelbacherorum - Abdomen, S6, with two obvious SINUOUS raised lines on the sides of that segment, if one draws an imaginary diagonal line from the tip of one line and connects that line about three-quarters of the way down most of the raised line will lie to the interior of the imaginary line (1)
P. utahensis - Abdomen, S6, with two raised lines on the sides of that segment, if one draws an imaginary diagonal line from the tip of one line and connects that line about three-quarters of the way down most of the raised line will be either congruent with the imaginary line or to the outside of it (1)
Male, T6, small lateral tooth
Absent (5)
Present (1)
Male, T7, pygidial plate, shape of rim
Angular, roughly trapezoidal, with clear corners (4)
Semi-circular end rounded, without any corners (4)
Male, abdomen, T2, hair bands
1 hair band ONLY basally, sometimes only visible laterally (4)
2 hair bands BOTH basally and subapically, sometimes incomplete medially or only visible laterally (3)
Male, antennae, F1 length
F1 less than F2 (5)
F1 equal to F2 (1)
Male, head, clypeus, color
With yellow (4)
All black (3)
Male, head, malar area
NARROW, width of space between the eye and mandible is less than the width of F1 (6)
WIDE, width of space between the eye and mandible roughly equal to the width of F1 (2)
