P. albitarsis vs. P. labrosiformis and P. aestivalis
 P. labrosiformis and P. aestivalis - Abdomen, T2, pattern of pits, MINUTE, OBVIOUS, but small as pin pricks, and UNEVENLY distributed, being dramatically more dense at the base than near the depressed apical rim (2)
 P. albitarsis - Abdomen, T2, pattern of pits, DISTINCT, DEEP, and EVENLY separated, or nearly so, by about 1-2 pit diameters from the base to the depressed apical rim - T2, the basal pits may be ever so slightly more dense than the more apical pits, but not dramatically so (1)
P. helianthi vs. P. solidaginis vs. P. rudbeckiae
 P. rudbeckia and P. solidaginis - Thorax, scutum, pattern of pits, CLOSE laterally and anteriorly, becoming obviously more sparse near center of scutum (2)
 P. helianthi - Thorax, scutum, pattern of pits, SPARSELY SCATTERED over entire scutum (1)
P. labrosiformis vs. P. labrosus and P. aestivalis
 P. labrosus and P. aestivalis - Thorax, scutellum, pattern of pits, SPARSE, or at least with large, shining, mostly pit free areas (2)
 P. labrosiformis - Thorax, scutellum, pattern of pits, DENSE throughout (1)
P. labrosus vs. P. aestivalis
 P. aestivalis - Thorax, mesopleura, pattern of pits when viewed from the side, NOT uniformly pitted, front and top sections of the mesopleura are much more densely and roughly pitted than the back and mid sections which are largely shining (1)
 P. labrosus - Thorax, mesopleura, pattern of pits when viewed from the side, UNIFORMLY PITTED throughout (1)
P. parvus vs. P. pauper vs. P. virginicus
 P. parvus - Abdomen, T3, surface appearance, with exceedingly MINUTE PITS that roughen the appearance such that the main part of the segment appears slightly rougher than the depressed rim, the pits on T1 and T2 are much clearer than those on T3 (1)
 P. pauper - Abdomen, T3, surface appearance, lacking or with very SPARSE PITS, such that the main part of the segment appears only as rough as the depressed rim, T1 and especially T2 look very much this same way (1)
 P. virginicus - Abdomen, T3, surface appearance, with TINY but clearly DISTINGUISHABLE PITS on the main part of the segment, the same as seen on T1 and T2, the rim is pitless (1)
P. rugosus vs. others
 Others - Head, vertex, NO bumps or tubercles located above each eye (14)
 P. rugosus - Head, vertex, a ROUNDED BUMP or tubercle located above each eye, about twice the diameter of the lateral ocelli (1)

 Hair standing straight up, generally of medium length (7)
 Hair suberrect, very short, appearing as if parted and combed away from the midline (7)
 Lacking hair (5)
Thorax, scutum, spacing of pits on the upper half - This DOES NOT include the extreme marginal areas
 Interpit distances VARIABLE, not uniform throughout (8)
