5. Head, mandible, integumental color

32All dark, brown to black, although sometimes the TIP of the mandible may have a golden smear on it    21With at least some degree of yellow coloration basally, not including the common gold coloration that may be found near the apex of the mandible   

6. Head, clypeus, light integumental markings

301. Clypeus all dark, brownish to black    162. With a strip of yellow along the rim of the clypeus, often with a slight medial point which is directed a variable distance toward the top of the clypeus but DOES NOT extend all the way, at most this strip of yellow comes to a fifth of the length of the clypeus from the top    153. Clypeus nearly entirely light-colored, although there are dark spots near the top which extend from the tentorial pits slightly into the clypeus such that the light integumental markings appear something like an inverted T, the base of which reaches the rim of the clypeus    14. Clypeus entirely light-colored, sometimes with a hint of black at the tentorial pits which DOES NOT intrude further into the clypeus   

7. Head, paraocular area, presence and extent of integumental light markings

471. All BLACK - With no light integumental markings    42. YELLOW present - Usually just a small dot but sometimes extending along the outside of the clypeus up above its intersection with the supraclypeus   

8. Head, supraclypeus, light integumental markings

43Absent - There are no light integumental markings present on the supraclypeus    7Present, Partial - Taking the form of a weak or obscure dot or patch which is limited usually apicomedially    10Present, entire or nearly so - Taking the form of a wide bar which covers nearly the entire supraclypeus at least in terms of width   

9. Head, antennae, length of the 1st flagellar segment, F1 - Note that this is measured along the longest side of thesegment

151. Short - Ranging from approximately equal to F2-3 to nearly equal to F2-4    372. Moderate - About equal to F2-4 or greater, but not as long as F2-5    153. Long - About equal to F2-5 or greater   

10. Thorax, scutum, hair color

171. All light - Whitish to yellowish    82. Orange to light brown - Orangish to light brown    193. Mixed, light hair dominant - Primarily light, whitish or yellowish, but with some small number of darker hairs which may be easily overlooked if not careful, these limited dark hairs often ONLY found medially so the rims of the scutum appear only lightly haired    324. Mixed - A mixture of light and dark hairs, with the presence of both colors readily apparent throughout, although light hairs are usually still dominant    35. All dark - All dark or nearly so, brownish or black, only a very few light hairs present if any   

11. Thorax, mesepisternum, hair color

431. All light - All hairs are white to off-white or yellowish to sometimes orangish    172. Mixed, primarily light - With primarily light hairs, but a VERY SMALL number of darker hairs are present near the top of the mesepisternum that are usually easily overlooked    63. Mixed, dark at the top - With both light and dark hairs present in appreciable numbers, but the dark hairs are limited to the top half    64. Mixed, dark at the bottom - With both light and dark hairs present in appreciable numbers, the dark hairs restricted ventrally and the light hairs on top    25. All dark - All hairs are brownish or black   

12. Abdomen, terga, presences of distinct light apical hair bands - T2 is the best segment to use for this

231. Present - With a light apical hair band that stands in contrast to the color of the hairs in the basal region or hairs in the basal region much less dense, note that sometimes the bands may be weak and appear partially interrupted    182. Absent but appears present - The hairs along the apex are of about the same color and density of those at the base, BUT it appears to have bands nonetheless due to the integument of the apical rim being TRANSPARENT    33. Absent, band formed by integument rather than hairs - There is a white band formed on the integument itself, rather than by hair color, the hair color and density is uniform throughout the segment    204. Truly absent - The hairs on the apical rim of the segment appear to be the same color and density as the basal region or the dark and light hairs are thoroughly scattered throughout the segment and no clear light hair band is apparent along the rim distribution   

13. Abdomen, T2, color of hair - Be careful of worn specimens with hair rubbed off or specimens in which some hairs are MUCH SHORTER than others

201. All light - Whitish to yellowish or rarely somewhat orangish    272. Primarily light - Mostly light, although some darker hairs are also present    183. Mixed, light and dark about even - A thorough mix of light and dark hairs, hard to tell which is dominant    204. Primarily dark - Mostly dark, although some lighter hairs are also present    75. All dark - All dark, brown or black
