REMAINING (number with state)
Female, H. micheneri , H. simplex, and H. nemophilae, combination of characters
 H. simplex and H. nemophilae - Pits on scutum only slightly larger than those on T1 and T2 - Pits on T1 and T2 less than 1 pit apart (2)
 H. micheneri - Pits on scutum dramatically larger than those on T1 and T2, twice or more as large - Pits on T1 and T2 separated more than 1 pit apart, often much more, pits very small compared to other Hoplitis species (1)
Female, H. pilosifrons vs H. producta - Note - You will be looking into the OPENING where the sting emerges from T6 and S6, this is almost always open slightly, you cannot see the character listed below from the dorsal side of T6
 H. pilosifrons - Look for a row of short hairs on the UNDERSIDE of the rim of T6, to see this feature find the opening where the sting is located, this is usually slightly open, turn the specimen upside down and there will be a single row of short hairs about the same length as those on the dorsal top of T6, note that the hairs on the topside of T6 often jut over the rim and can be mistaken for hairs coming out from below, the hairs on the underside CLEARLY originate on the underside - In comparison larger and the white hairs on the far sides of the tergites longer (1)
 H. producta - Hairs on underside of the rim of T6 completely absent - In comparison smaller and hairs on the far sides of T6 shorter and sparser (1)
Female, H. simplex vs H. truncata
 H. simplex - The clypeus uniformly pitted, without any longitudinal raised line - There is only 1 size class of pit on the scutum and the abdomen - In direct comparison, smaller (1)
 H. truncata - In most specimens there is an unpitted but raised median longitudinal line running down the clypeus, the outline or the sides of which is often a bit indistinct - There are 2 size classes of pits on the scutum and the abdomen, there are the large ones and then there are pits about one sixth the size of the large ones that occur in between the large ones - In direct comparison, larger (1)
Female, abdomen, T6, surface
 Mostly visible, less than 50 percent obscured by hair (6)
 Mostly obscured, 50-80 percent covered by short, tan hairs, especially toward the rim (5)
Female, abdomen,T6, shape in profile
 Rim distinctly bent to an angle roughly 110 to 135 degrees relative to the rear face of segment (6)
 Rim indistinctly bent to an angle between 145 and 170 degrees relative to the rear face of the segment (6)
Female, head, clypeus, presence or absence of longitudinal median raised ridge - Usually most prominent on lower half
 Absent, though there may be an UNRAISED line without pits, particularly on the upper half (10)
 Present (1)
Female, head, clypeus, rim
 Viewed from top the rim is straight or nearly so, when viewed end on the rim appears bent up and back on either side of center making the rim appear to be thickened (7)
 Viewed from top the rim is straight or nearly so, when viewed end on the rim may appear a little bit thick, but not because it is bent up and back (4)
 Viewed from top the rim is distinctly concave in center, when viewed end on the rim edge is thin and narrow , though may undulate (3)
 With large, very distinct tubercle or bump on rim, visible from top and end on (2)
 Viewing the face of the clypeus from above, the center half or more of the rim is modified, forming a slightly thickened and elevated bar with two widened areas or knobs at either end, the profile of the rim in this section is slightly concave or straight and outside of this modified area the sides of the clypeus, past the knobs, angle back toward the eyes (1)
Female, head, clypeus, surface sculpting
 Pits in center distinct despite being somewhat crowded (7)
 Pits in center densely crowded and NOT distinct (6)
 Pits in center sparse and fine, may be un-pitted down the middle line (1)
Female, head, mandibles, number of teeth
 3 teeth (8)
 4 teeth (2)
 Tip is a single flat blade or at most with a tiny tooth notched out of the lower portion of the tip (1)
Female, scopa, legs and sides of thorax, hair color
 White (9)
 Black (1)
Male, H. pilosifrons vs H. producta, combination of characters
 H. pilosifrons - S2 with a low and broadly rounded mound, forming an obtuse angle latitudinally, without a flattened rear face - Tip of T7 usually extended out as a parallel-sided projection (1)
 H. producta - S2 bulge very tall with a rounded tip, latitudinally forming an acute angle, the rear face noticeably flattened, reminiscent of a large nose - Tip of T7 usually with only a slightly narrowed tip to its generally triangular shape (1)
Male, abdomen, S1 and S2, rim
 Median spine ABSENT (9)
 Median spine PRESENT (1)
Male, abdomen, S3, hair fringe
 Thicker in center (8)
 Uniform throughout (7)
Male, abdomen, S3, rim
 Dipped or incurved in center (6)
 Entire, no dips in margin (4)
 Not visible, obscured by hair fringe (4)
Male, abdomen, T7, rim
 Evenly rounded from side to side (3)
 Projected to a truncate, flattened rim (2)
 Roughly triangular in shape, tip can sometimes be extended out as an elongate, parallel-sided projection (2)
 Four lobed or toothed (1)
 Projected to a truncate, centrally angled rim (1)
 Rounded with sides slightly flared (1)
Male, head, antennae, last segment
 Slightly tapered, not hooked, or only slightly so (7)
 Drawn to a distinctly hooked point (3)
Male, head, antennae, segments 8-11
 Longer than wide (6)
 Wider than long by 1.5 to 2X (2)
 Wider than long by less than 1.5X (2)
 Segments 8 and 9 wider than long, segments 10 and 11 longer than wide (1)
Male, head, mandible, fringe of hair along the bottom
 Majority of hairs less than 1/2 the greatest width of mandible, generally sparse (7)
 Majority of hairs equal to or greater than 1/2 the greatest width of mandible, dense (4)
Male, micheneri vs sp. nemophilae, abdomen, S2 and S3, shape of rim
 S2 rim nearly straight, S3 rim shallowly and broadly incurved (1)
 S2 rim slightly produced, S3 rim with strong median emargination (1)
