REMAINING (number with state)
Abdomen, S6, shape
 Narrowing toward the tip with small, possibly minute, teeth present just below the tip on the rim (10)
 Appearing as a small elongate triangle set upon a much larger segment with rounded shoulders (7)
 Sides evenly convex, narrowing toward the apex, appears like half of an ellipse (6)
 Apex tri-dentate and narrowed from segment base (1)
 Appearing as a long, parallel-sided, straight spine set upon rounded shoulders, a fan of hairs as long as the spine occur on either side of the spine spreading to the edge of the shoulders (1)
Abdomen, T6, median ridge and pattern of pits
 Median ridge PRESENT, overall shape and pitting variable - Most common state (18)
 Median ridge ABSENT, smooth and unpitted LINE present medially where ridge would occur, otherwise pitted (3)
 Median ridge ABSENT, wide apical margin unpitted, otherwise pitted (3)
 Median ridge ABSENT, evenly pitted throughout (2)
C. alternata vs. C. hunteri - Difficult to Separate and Subtly different
 C. alternata - Thorax, axillae, projecting free tip end relatively short, projecting by about one quarter to one third the the length of the suture between the axillae and the scutellum - - Thorax, pronotal ridge, less produced but does not rise in height above the surrounding hairs - - Thorax, scutellum, boundary between dorsal and the narrow posterior face, medial fourth usually with a SLIGHTLY raised carina or ridge projecting upwards from the dorsal face - - Abdomen, T6, pits smaller (1)
 C. hunteri - Thorax, axillae, projecting free tip end relatively long, projecting by about one one third ot one half the the length of the suture between the axillae and the scutellum - -Thorax, pronotal ridge, more produced such that it usually extends slightly above the surrounding hairs - - Scutellum, boundary between dorsal and the narrow posterior face, medial fourth flat without any raised or projecting ridges or boundaries - - Abdomen, T6, pits larger (1)
C. coturnix vs. others
 Others - Larger, all other Coelioxys are larger than C. coturnix - NOT AS HAIRY, the mesepisternum has none of the fat, flattened hairs that may occur on the tergite rims, but may have a fair amount of long, normal white hair on the segment, but the black integument is always very clearly visible (22)
 C. coturnix - Small, 8mm, the size of Megachile rotundata, its presumed host - Hairy, the white, fat, flattened, appressed hairs that line the rim of the tergites in most Coelioxys also cover or nearly cover the mesepisternum in this species (1)
C. galactiae vs C. obtusiventris, S6, color of hair fringe on rim apex
 Brownish (1)
 White (1)
C. hunteri vs C. alternata and C. texana, Abdomen, S6, shape of rim
 Pointed in the center (2)
 Bluntly rounded (1)
C. modesta vs. All Others
 All Others - Do not have this character (22)
 C. modesta - Abdomen, T6, at the very end is a small knob that rises apruptly upward at about a 45 degree angle, knob is about half the size of an ocelli (1)
C. moesta vs C. porterae
 C. porterae - Abdomen, S6, on sides where the edge broadens very near the base of segment with a dense patch of short tan hairs - Head, clypeus, rim clearly convex - In direct comparison slightly larger and abdomen is duller from greater amount of microscopic lines (1)
 With some scattered hairs, but lacking a dense patch of short tan hair (1)
C. octodentata vs C. rufitarsis
 C. octodentata - Red or amber on hind legs tends to include the entire tarsus, tibia, and much or all of the femur - T6 with weak or no angle along its lateral edges, see illustrations for both species under their species pages - In direct comparison slightly smaller (1)
 C. rufitarsis - Red or amber on hind legs tends to be restricted to the basitarsus and the apical end of the tibia - T6 with a strong angle along its lateral edges, see illustrations for both species under their species pages -- In direct comparison larger (1)
C. rufitarse vs C. moesta and C. porterae, abdomen, T6, overall profile of the lateral sides of this segment when viewed directly from above - As in the genus in general this is an elongated segment, coming to a narrow point
 C. moesta and C. porterae - In both these species the overall shape is that of a smooth, gentle, sigmoid curve uninterrupted by any angles, although, interior to the sides there may be shallow hollows or indentations of various sorts from about half to one third of the way towards the tip, but these not influencing in any significant way the smooth outline of the segment (2)
 C. rufitarse - The overall shape clearly not that of a smooth sigmoid curve, about half way down the sides the outline clearly broken by a sharp angle inward creating distinct obtuse corners, these corners formed by the presence of a wide and deep trough or hollow that cuts into the segment below these corners and runs towards but not past the centerline (1)
C. sayi vs all, clypeus rim
 Others - Not as stated above (22)
 C. sayi - Clypeus clearly indented in the center, the rim forming 2 evenly curved lobes, visible even when hair covers the entire clypeus, the lobes very slightly elevated at their ends above the rest of the surface (1)
C. sodalis vs C. immaculata, T6, modifications made to plate surface
 Raised ridge set just in from the rim IS continuous all the way around the tip, the median longitudinal line extends from the base to the raised ridge, NOT to the absolute edge of the tip (1)
 Raised ridge set just in from the rim is NOT continuous and begins to develop near the indentations found on either side of the median longitudinal line, this line extends from the base to the absolute edge of the tip (1)
Head, Ocellus, Middle One
 Surface surrounding central ocelli is uniformly pitted and not raised (18)
 Nearly encircled by a rounded mound, clearly raised above the surrounding surface, mound is largely unpitted, but may be split by pitted lines at the front and the back (5)
Head, clypeus, profile, general shape
 Flat or nearly so, rim not scooping up or thickened (21)
 Rim area gently scooping up, otherwise flat and not thickened (2)
 Thickened and rounded at rim (2)
Head, mandibles, type and pattern of hair
 Lacking hair or with thin, tan or black hairs that do not greatly obscure the surface, if with any white hair, then present only at the base (19)
 80-100% of basal 3/4 obscured by short, dense, white, matted hairs (11)
Legs, color
 Femur and tibia orange to reddish-orange similar in color to tarsal segments (17)
 Femur and tibia reddish-brown, brown, or black in contrast to lighter tarsal segments (13)
