REMAINING (number with state)

 Somewhat concave in center, NO central spine (1)
Female, S. coarctatus vs. S. lateralis
 S. coarctatus - Head, antennae, flagellar segment 1 clearly WIDER THAN LONG - Thorax, longitudinal length of line of pits or cells just below the metanotum on the propodeum, GREATER or equal to that of metanotum (1)
 S. lateralis - Head, antennae, first flagellar segment LONGER THAN WIDE or equal - Thorax, longitudinal length of propodeal cells LESS than length of metanotum - Note - There are often light spots on T5 which, when present, are distinguishing (1)
Female, S. nitida vs. S. foederalis
 S. foederalis - Abdomen, overall shape of S6 rim outline, STRAIGHT with a slightly concave area in the central portion, which is often hidden by hair - In direct comparison, smaller and narrower than S. nitida with the stripes on the tergites more prone to being slightly interrupted in the center (1)
 S. nitida - Abdomen, overall shape of S6 rim outline, dominated by the TWO PROMINANT LOBES to either side of a clearly visible central concave area, this central concave area is wider than the lobes to either side - In direct comparison, larger and stouter than the other species with tergal stripes that are rarely interrupted in the center (1)
Head, Clypeus, Color
 All black (23)
 Mix of black and yellow (4)
 80% or more yellow (2)
Head, Color of Hair - Look closely for dark hairs, especially on vertex
 Light, white to yellow (19)
 Mixed dark and light hairs (6)
Head, Region between the compound eye and the base of the antenna
 All black (16)
 Greater than 75% yellow (6)
 Narrow yellow line along edge of eye (2)
Male, Abdomen, T3-T4, appearance of yellow or off-white markings
 Continuously or nearly continuously banded across each segment (5)
 Markings appearing only as spots (3)
 Banded with a substantial gap in center (2)
 Lacking markings of any kind (2)
Male, Abdomen, T7, Shape of rim when viewed from top
 Flat across end, without modification (5)
 Slightly concave in the center (3)
 Flat across end, but with a short, raised ridge, as a mountain peak, set just in from the rim in the center - The ridge is perpendicular to the rim (2)
 Sharply, and obviously pointed in the center of the rim (1)
 Tri-lobed, the center lobe narrowed to a sharp, inconspicuous point (1)
Male, S. australis vs. S. grossa
 S. australis - Likely the commoner species, it has been recorded from Florida to New Jersey (1)
 S. grossa - No males have been described (1)
Male, S. foederalis vs. S. lateralis
 S. foederalis - Abdomen, T1-T5, banded, with each band having a SMALL GAP in the center (1)
 S. lateralis - Abdomen, T1-T4 and usually T5, with one PAIR OF LATERAL PATCHES, and sometimes with a second pair of patches on T3 and T4 (1)
Male, S. nitida vs S. subemarginata
 S. nitida - Head, clypeus, rim smoothly forms a gentle convex curve, may or may not be a tooth at the far sides of the rim - Abdomen, S3, central area not concave, center of the segment with a swelling that rises from the center and increases in height towards the rim, at the rim at the tip there is a slight emargination - In direct comparison clearly larger and broader - More southern in range and likely nest parasite of Osmia bucephala (1)
 S. subemarginata - Head, clypeus, rim with two prominant teeth located just to either side o the center line and forming a concave emargincation between the two, and additional tooth is set at the far sides of the clypeal rim - Abdomen, S3, the ENTIRE central region of the segment is hollowed out and concave, like a shallow bowl, at the very center of the rim is a small shiny, prefect, unpitted oval that clearly stands out from the rest of the surface - In direct comparison smaller and narrower - More northern in range and known nest parasite of Osmia simillima (1)
S. ater vs. S. diversicolor
 S. ater - Female only, male as of yet undescribed - Thorax, scutum, pit appearance, generally GREATER than 50 percent of pit TOUCHING, there may be specimens, however, that are intermediate - Size, average of 10mm - Comparatively, larger on average than S. diversicolor - Range, only known from FLORIDA (2)
 S. diversicolor - Thorax, scutum, pit appearance, usually FEWER than 50 percent of its pits touching - Size, average of 8mm - Comparatively, smaller on average than S. ater - Range, throughout the SOUTHEAST including Florida (2)
S. australis vs. S. louisiae
 S. australis - Thorax, propodeum, VERTICAL without any band of squared pits, edge of scutellum lines up or slightly projects over propodeal face - - Abdomen, T3-5, with yellow lateral markings that are clearly broken in the middle thus leaving the centers BLACK not yellow (2)
 S. louisiae - Thorax, propodeum, mostly vertical, but there is a band of large SQUARED PITS that are visible dorsally below the scutellum which does not project over those pits or the rear face of the propodeum - - Abdomen, T3-5, with latitudinal bands of YELLOW to ferruginous across the center, the lateral extent of the yellow varies (2)

Thorax, Propodeum, Distinct row of large square or rectangular cells or pits located just below the junction with the metanotam - Tricky, look closely, completely, and carefully
 INTERRUPTED Squarish pits present over more than 25% of propodeal triangle, but with at least a small, smooth, unpitted area in the center - Look carefully (16)
