2. Sex, number of antennal segments

312, female    313, male   



3. Female, mandible, 2 ridges that run down the outer surface

1The two ridges MERGE at or before reaching the basal third    2The two ridges remain SEPARATE to the base, or if merging, then merging near the base   



4. Female, clypeus, rim

1A knob half the size of the ocelli present at the FAR sides of the rim    2Small knobs, much less than half the size of the ocelli present on the sides of the slight concave central portion of the rim, may be none or 1-3   



5. Female, pits on T2 and T3    [Explain]

2Equally sized or just minutely smaller on T2    1Pits of the 2nd segment noticeably smaller than those of the 3rd segment   

6. Male, abdomen, shape of S1    [Explain]

1H. carinata - Rim squared off or concave and with a very tall, clearly taller than wide, prominent mound in the center of the segment    1H. leavitti - Abdomen, S2, RIM PROFILE is slightly convex, somewhat flattened, blunted, but always OBTUSE, white hairs often obscure the tip, pitting towards the apex of the central mound of S2 more dense, in direct comparison, and interspaces at the apex are DULLED by microscopic lines    1H. variolosus - Abdomen, S2, RIM PROFILE is clearly lengthened and POINTED and is approximately 90 degrees, white hairs never obscure the tip, pitting towards the apex of the central mound of S2 less dense, in direct comparison, and interspaces at the apex are SHINY and mirror like   




7. Male, length of vertex

1Vertex long, distance from lateral ocelli to rear of margin head GREATER than distance between lateral ocelli    2Vertex shorter, distance from lateral ocelli to rear margin of head EQUAL to or LESS than distance between lateral ocelli
