REMAINING (number with state)
A. ainsliei vs A. autumnalis
 A. ainsliei - The axillae are longer, only barely more than half of their inner margin being shared with the scutellum - If you run an imaginary line across the tips of the axillae they are equal to or just slightly shorter than the rim of the scutellum - The hair band on T2 is of about equal width throughout and lines the rim the entire way (1)
 A. autumnalis - The axillae are shorter, about two-thirds to three-fourths of their inner margin shared with the scutellum - If you run an imaginary line between the tips of the axillae this line will clearly be much shorter than the longitudinal length of the scutellum - The hair band on T2 is constricted medially and often pulled away from or not reaching the the rim in that area (1)
Abdomen, S4, apical hair fringe
 Fringe composed of long hair on sides with hair in middle lacking or dramatically shorter (11)
 Fringe composed of ALL long hair, or with the hairs in the middle only slightly shorter than hair on the sides (8)

 1. Both primarily BROWN/BLACK (17)
 2. Both primarily AMBER (2)
 3. T1 AMBER, T2 primarily BROWN/BLACK (2)

E. australis vs E. autumnalis
 E. australis - Tips of axillae projecting only slightly from sides of scutellum reaching only slightly past the middle of the scutellum - Cheeks approximately 1/3 as wide as the eye - T1 complete, with no medial interruption (1)
 E. autumnalis - Axillae robust, tips clearly projecting from the sides of the scutellum reaching very nearly to the rear margin of the scutellum - Cheeks approximately 1/2 as wide as the eye - T1 may be either complete or with a small medial interruption (1)
E. autumnalis vs E. erigeronis
 E. autumnalis - The space between the medial ocelli and the antennae is densely pitted, with few pits, if any, having pit interspaces greater than one pit diameter, appearing in general dull and less shiny as a result - Scutum entirely densely pitted, with no pit interspaces greater than one pit diameter - Mesepisternum densely pitted with primarily circular or nearly circular pits which are only marginally larger than those on the scutum, if at all - Inner edge of the axillae, where they have left the scutellum, only very slightly curved inward, if at all, such that even when slightly curved they could be confused for straight (1)
 E. erigeronis - The space between the medial ocelli and the antennae is more sparsely pitted, with many pits having pit interspaces greater than one pit diameter, appearing shiny and smooth between the pits as a result - Scutum partially densely pitted, quite often with multiple areas of sparsity where the pit interspaces exceed one pit diameter - Mesepisternum with irregular reticulations forming both circular and non-circular enclosures throughout, these enclosures with their maximum width almost always clearly greater than the average pit diameter on the scutum - Inner edge of axillae, where they have left the scutellum, very clearly curved inward and hook-like such that it could not be mistaken for straight (1)
E. banksi vs E. minimus
 E. banksi - Color of hair on dorsum of thorax and abdomen is WHITE - Pygidial plate with pits that are obvious, moderately deep, and quite dense, though not touching, also generally DARK in color, similar to that of the terga (1)
 E. minimus - Color of hair on dorsum of thorax and abdomen is YELLOWED - Pygidial plate with pits that are shallow, indistinct and sparse, also often lighter in color than the terga, though not necessarily so (1)
E. canadensis vs all, thorax, color of hair on metanotum
 All others - Entirely, or almost entirely covered with thick white hair (19)
 E. canadensis - With a SPOT of DARK hair in the center and white hair on the sides (1)
E. glabratus vs E. zonatus - T1 and T2, color of depressed apical third of both segments
 E. glabratus - Dark BLACK or BROWN (1)
 E. zonatus - AMBER, the same color as the basal portion of each segment (1)
E. howardi vs E. lectoides
 E. howardi - Slightly convex region, 2-3 ocelli diameters wide, slightly anterior to the space between the lateral ocelli and compound eye is entirely smooth WITHOUT pits - Scutum DENSELY pitted, with very few pits spaced farther apart than one pit diameter - The interior margin of the axillae nearly straight from base to tip only slightly, but evenly concave (1)
 E. lectoides - Pit density only SLIGHTLY decreased in the convex area of the face slightly anterior to the imaginary line running from the lateral ocelli and the compound eyes, at most the distance between pits is about 1 ocelli diameter or slightly greater - Scutum SPARSELY punctate, with many pits spaced farther apart than one pit diameter - The interior margin of the axillae shift to strongly concave at the point where the axillae depart from the border with the scutellum, best seen at 20x magnification (1)
E. interruptus vs E. canadensis, thorax, scutum, pattern of white mat like hair on upper half
 E. canadensis - Forming two short stripes that converge at the midline, forming a V-shape (1)
 E. interruptus - Forming a pair of very distinct stripes that are narrow above and become quite bulbous at the bottom, almost as a tear drop (1)
E. interruptus vs E. minimus, T1, basal hair band
 E. interruptus - The basal band on T1 is widely and distinctly INTERRUPTED in the middle (1)
 E. minimus - The basal band on T1 is COMPLETE, with no medial interruptions (1)
E. lanhami vs all, number of submarginal cells in the front wing
 All other - Generally THREE (16)
 E. lanhami - TWO (1)
E. pusillus vs E. scutellaris, T1, basal face
 E. pusillus - Basal face of T1 completely covered in hair all the way down to the junction with the propodeum, no gap in the middle (1)
 E. scutellaris - Basal face of T1 with dense hair on upper 2/3 of sides, basal 1/3 near junction with propodeum lacking hair or with extremely thin hair, and possibly with a gap in the hair all the way down the middle of the face (1)
E. weemsi vs all
 DEFAULT option, choose this option first to select only well known species (19)

 NORMAL, area essentially flat and deeply pitted (18)
 With a SHINY, unpitted, slightly SWOLLEN along the inner margin of the eye in this area - If with any pits, then they will be tiny as pin pricks (4)
