REMAINING (number with state)
Abdomen, T6, medial area
 No protuberance (19)
 Protuberance, covered by hairs (7)
Abdomen, T7, projection sticking prominently out from the end - Shape best viewed ventrally
 With a single median flange, about equally broad as long or longer than broad, often triangular to roundly triangular, apex pointed or with a low angle but not notched (14)
 With a single broad median flange, broader than long, either evenly rounded or truncate and flattened (6)
 No apical plate, instead with two widely separated points or tubercles (2)
 With single median flange, about equally broad as long, triangular with apex notched (1)
C. apacheorum vs C. timberlakei, combination of characters
 C. apacheorum - Smaller, 4-4.5 mm long - Clypeal mark filling entire clypeus - Distributional records for California usually transmontane, although a few specimens have been collected in Monterey Co. and San Luis Obispo Co. (1)
 C. timberlakei - Larger, 4.5-6 mm long - Clypeal mark does not fill clypeus completely - Distributional records for California cismontane (1)
C. cobaltina vs C. cockerelli
 C. cobaltina - Large,7-10mm - Margin of S5 with obtusely bidentate projection medially - Body green or blue often with purplish highlights on the abdomen, pitting dense and extensive - Base of mandibles yellow (1)
 C. cockerelli - Small,3-5mm - Margin of S5 smooth without medial projection - Body dark brown and minimal pitting especially on the head - Base of mandibles dark w/o yellow markings (1)
C. dallatorreana vs all others
 All others - Male specimens and/or species descriptions were used to develop this guide (23)
 C. dallatorreana - This species reproduces primarily by parthenogenesis and males are extremely rare, no male specimens could be obtained for the development of this guide and written descriptions provided minimal information (1)
C. hurdi vs C. nanula, combination of characters
 C. hurdi - Facet of femoral tooth broad, hairs entire length of basal edge - Apical plate of T7 wider than long (1)
 C. nanula - Facet of femoral tooth obscure or absent, hairs usually long and curved over top of tooth - Apical plate of T7 as wide as long (1)
C. pacifica vs C. punctigena, combination of characters
 C. pacifica - Basal side of femoral tooth facet concave, surface of facet concave - A few long hairs on basal edge of femoral tooth (1)
 C. punctigena - Basal side of femoral tooth facet straight, surface of facet flat - Hairs along basal edge of femoral tooth all short and without a few long sparse hairs (1)
C. pacifica vs C. sequoiae, combination of characters
 C. pacifica - Projection on T7 triangular to roundly triangular - S6 with the single median tooth not divided at the apex - Pitting on mesepisternum distinct and crisp (1)
 C. sequoiae - Projection on T7 evenly rounded, apex not coming to a point - S6 with the single median tooth bifid, or divided at the apex - Pitting on mesepisternum not crisp but rough and irregularly spaced (1)
Fore leg, tibia
 Ivory mark only on base of tibia (14)
 Ivory mark on both the base of the tibia and the apex of the femur (8)
 Ivory stripe extending at least three-fourths the distance to the entire length of the tibia (7)
 Ivory stripe extending less than three-fourths the distance (2)
Forewing, color
 Wing similarly colored throughout, although some may be slightly darker at the apex (23)
 C. melanoptera - Apex of forewing distinctly darker than base of wing (1)
Head, parocular markings
 Without parocular markings (20)
 Parocular markings restricted to the base of the eye (4)
 Parocular markings extending from base to near antennal sockets (1)
Head, preoccipital ridge vs carina
 Preoccipital carina present (17)
 Preoccipital ridge without a carina (11)
Hind leg, femur, femoral tooth shape
 Obtuse (17)
 Tooth not apparent, only a thickening in the shape (6)
 Right angled, or slightly obtuse (3)
 Acute (2)
Hind leg, femur, hairs on apex of femoral tooth
 Straight hairs (17)
 Curved hairs (10)
 No hairs (7)
Hind leg, femur, hairs on basal facet of femoral tooth, but not including hairs on the lower edge
 No hairs on surface of facet, or if hairs present they are very sparse (20)
 Short hairs on surface of facet, hairs may be erect or oppressed (5)
Hind leg, femur, hairs on edge of femoral tooth between apex and trochanter
 Hairs all similar length (18)
 Hairs longest near trochanter (8)
 No hairs on the edge of tooth (6)
 Hairs longest near apex (5)
Hind leg, femur, position of femoral tooth along length of femur
 Apex of tooth equidistant to tibia and trochanter, or not obviously closer to either end of femur (16)
 Apex of tooth appears to be closer to the trochanter (5)
 Apex of tooth appears to be closer to the tibia (3)
 Lacking tooth, but widest part of femur closest to the trochanter (3)
Hind leg, trocanter
 Angular (14)
 Rounded (10)
