REMAINING (number with state)
E. hamata vs all, hind tibial spur, shape - Look closely 2
 All others - NOT hooked, may be gently curved toward the tip (11)
 E. hamata - HOOKED dramatically at tip, but only at tip, the angle of the hook is about 90 degrees, otherwise the spur is straight (2)
Female - E. atriventris vs E. rosae - Species with dark scopa - Combination of characters
 E. rosae - Wide depressed rim of T2 with pits largely restricted to the base of the depressed area in the center of the segment, if pits are present in the middle of the central area then they are scattered, at very low density, and leaving a very wide unpitted rim - The distance between the eye and the intersection of the edge of the mandible and the clypeus slightly narrower than the widest part of the scape - FAR sides of labrum with no slightly raised area, pits extending uniformly across entire labrum, at times there might be some vaguely less pitted area on the far side, but it would at most be 2-3 pit diameters wide (2)
 E. atriventris - Wide depressed rim of T2 with pits present throughout, usually with a SLIGHTLY lower density in the center and only a NARROW unpitted section right along the rim - The distance between the eye and the intersection of the edge of the mandible and the clypeus wider that the widest part of the scape - FAR sides of labrum with an unpitted slightly raised area, the unpitted area easily 5 or more pit diameters wide (1)
Female - E. belfragei vs E. dubitata
 E. belfragei -T3 and T4 with complete white hair bands set just behind the apical rim - T5 with long white hairs interspersed with the usual dark hairs on the far sides, set just back from the rim - S2-4 with long white hairs along the apical rim with some long dark long ones intermixed towards the center and dark hairs about half as long basally (1)
 E. dubitata - T3-5 hairs all dark - S2-4 with long ORANGISH hairs along the apical rim and SIMILARLY colored hairs about half as long basally (1)
Female, abdomen, color of hair
 All dark except light hair on the base of T1, no distinct hair bands (3)
 Light on T1, T2-T5 with STRONG apical or submedian bands of light hair, dark hair basally and or on the central disc region (3)
 Nearly completely covered in bright yellow-orange hair, no distinct hair bands (1)
Female, hind leg, color of scopal hairs
 Off-white (3)
 Orange (3)
 Dark (2)
Male - E. atriventris, E. dubitata, E. rosae - Very similar species - Combination of characters
 E. dubitata and E. rosae - These 2 are told apart in a separate character. Both appear to be discernable from E. atriventris by the following characteristics, SOME OF WHICH MAY NOT BE PRESENT ON ALL SPECIMENS, so use a weight of evidence approach - Labrum with no black present, entirely yellow - Clypeus entirely yellow - Gap between the clypeus and the eye clearly less than one half the width of the flagellum - S6 with 2 short, clearly and prominently raised lines or ridges, the raised nature of these lines clearly visible when looking at them from the side, each about one quarter the width of the segment, these lines run parallel to the sides of the S6 but are set back from the rim, Timberlake suggests that only E. dubitata has these lines, but so far all the identified E. rosaea in the collection have lines too - The shortest side of F1 about as long as the width of the base of the segment (2)
 E. atriventris - Told from E. dubitata and E. rosae by the following characteristics, SOME OF WHICH MAY NOT BE PRESENT ON ALL SPECIMENS, so use a weight of evidence approach - Labrum with a narrow strip of black around the rim of the labrum, most obvious on the sides - Upperside of clypeus often edged with black - Gap between the clypeus and the eye about two quarters to three quarters the width of the flagellum - S6 with either no raised line on the segment at all, or 2 vague raised lines that runs about one quarter of the way latitudinally across the segment from the sides - The shortest side of F1 clearly longer than the width of the base of the segment (1)
Male - E. dubitata vs E. rosae
 E. dubitata - Rim of T6 fringed with long WHITE hairs - S8 medially deeply cleft with acute v-shaped notch, hairs present throughout the rim except in cleft, TO VIEW YOU MUST PULL THE GENITALIA - Set slightly back from the apical rims of T3 and T4 are COMPLETE bands of white prostrate hairs, these hairs, when compared to E. rosae, almost twice as long (1)
 E. rosae - Rim of T6 fringed with long DARK hairs - No medial cleft to S8 - Set slightly back from the apical rims of T3 and T4 are usually incomplete bands of white prostrate hairs, these hairs restricted to the lateral sides of these segments, are very weak, and are often completely absent, compared to E. dubitata they are only half as long (1)
Male, abdomen, T3 and T4, color and pattern of hair
 Sparse dark hair, no hair bands (4)
 Dark across the entire base of the segments, narrow white to off-white hair band located along the base of the slightly depressed apical margins (3)
 Dark basally, though this dark area often retracted or hidden by the rim of the preceding segment, wide swath of short off-white to white hair covering part of disc and most of the depressed apical margin, hairs on the very edge of the rim may be dark (1)
 Golden orange basally, golden orange to off-white hair bands apically (1)
Male, antennae, length of 1st flagella segment vs 2nd
 1st not more than 1/3 the length of 2nd (6)
 1st nearly half the length of 2nd (2)
Male, fore wing, point where the 1st recurrent vein meets the 2nd submarginal cell
 About 3/4 the way or more across the cell (5)
 About 2/3 the way across the cell (2)
Male, head, labrum, color
 Entirely yellow (5)
 Yellow with narrow dark rim (2)
 Dark, possibly with small yellow spot in center (1)
Male, thorax, scutum, color of hair
 Off-white to yellow (7)
 Light to bright orange (1)
