 S. mandibularis - Spaces between pits dull to slightly shiny, running from completely flat to surface slightly uneven due to slightly raised lines on scutum, nowhere near as much as S. fattigi - Abdomen, T2 unpitted apical rim, taking up about half to 33 percent of the segment - Head, flagellar segments 1 and 2, combined length compared to width, CLEARLY LONGER than width - Size 6-7mm (1)
S. clematidis vs. S. galerus
 S. clematidis - Thorax, scutum, with only a slightly and obscurely depressed line from the anterior edge down the center, not at all similar to the paropsidial lines - Leg, hind tibia, dorsal edge with a series of small translucent REDDISH CURVED SETAE hidden among the larger white setae that cover the outer surface of the segment - Size, 9-10mm (1)
 S. galerus - Thorax, scutum, with a CLEAR DEPRESSED SULCUS or line runs like a shallow gully from the center of the anterior edge of the scutum about half way down, similar in width to the paropsidial lines - Leg, hind tibia, dorsal edge of the hind tibia with 2-4 hidden short curved setae in the center about half the size of the surrounding hairs - Size, 7-8mm (1)
S. clemetidis vs. S. dichrous
 S. clemetidis - Abdomen, Tergites, pits scattered to absent, often difficult to see, when present pits are often well over 1 pit diameter apart, large portions of tergites with any pits - In direct comparison smaller (1)
 S. dichrous - Abdomen, Tergites, pits, dense, obvious, touching to nearly touching throughout all the segments except for the rims - In direct comparison larger (1)
S. confertus vs. S. fattigi
 S. confertus - Head, 1st flagellar segment LONGER THAN WIDE - Clypeus, with a CLEAR DEPRESSED LINE running down the center dividing it into right and left hand sides - Size, 8-10mm (1)

S. davisii vs. S. johnsonii vs. S. pimpinellae vs. S. prosphorus
 S. davisii - Head, scape, HEAVILY PITTED, pits separated by about 1 pit diameter, surface dulled by many lines and reflecting little light - Scape length, LONGER THAN or equal to the distance from the edge of the antennal fossae to the rim of the clypeus - Leg, hind tibia, dorsal edge with a series of small translucent reddish curved setae hidden among the larger white setae that cover the outer surface of the segment - Thorax, scutum, HEAVILY PITTED, surface dulled by lines, distance between pits always less than 1 pit diameter - Compared to S. johnsonii the pits on the clypeus are denser with many overlapping one another in the center and few, if any, gaps greater than 1 pit apart (1)
 S. pimpinellae - UNIQUE, Wing with 2 submarginal cells - Head, scape, MODERATELY to heavily pitted, pits separated by about 1 pit diameter or more, surface varies from dull to shiny - Scape length, SHORT, not equaling the distance from the edge of the antennal fossae to the rim of the clypeus - Leg, hind tibia, dorsal edge with NO HIDDEN reddish curved setae - Scutum, HEAVILY PITTED, surface dulled by lines, distance between pits always less than 1 pit diameter (1)
 S. prosphorus - Head, scape, LIGHTLY PITTED, pits clearly separated by more than 1 pit diameter, surface very shiny and reflective - Scape length, LONGER THAN or equal to the distance from the edge of the antennal fossae to the rim of the clypeus - Leg, hind tibia, dorsal edge with a series of small translucent REDDISH curved SETAE HIDDEN among the larger white setae that cover the outer surface of the segment - Scutum, not as heavily pitted, surface SHINY BETWEEN PITS, distance between pits close, but at least some places in the center of the segment where there are clear spaces greater than 1 pit diameter (1)
S. galerus vs. S. prosphorus - Tricky to tell apart pair
 S. galerus - Head, Antenna, Scape, pitting OBSCURRED by a heavy background of microscopic lines that dull the surface - Thorax, Scutum, surface between the pits obscured by a heavy background of microscopic lines that dull the surface (1)
 S. prosphorus - Head, Antenna, Scape, pitting clearly visible, surface between pits smooth and MIRROR-LIKE - Thorax, Scutum, surface between pits SHINING and clear of microscopic lines (1)

 Ridge rounded over, not sharply defined (3)
Thorax, propodeum, triangle, percent distance from the base to the rim that raised reticulations are present
 1. 100 (15)
 2. 95 to 50 - Note, species that are not 100 percent will have a noticable bare, smooth, shiny area along the rim and often extending into a central smooth triangular area on the rear face extending from the center of the rim (1)
