Red Oak Borer - Enaphalodes rufulus

Red Oak Borer - Enaphalodes rufulus
Hwy 55 and Sedwick, Durham County, North Carolina, USA
July 6, 2005
Size: 30 mm
One last image showing middle and hind legs, etc. Note the two prominent tubercles on pronotum (each side of median line), and here with a tubercle in the middle. Dillon, p. 586, (1) describes as "Pronotum usually with a small tubercle each side of the median line before middle, behind with a smooth, slightly raised space medially, not always distinct."

Refer also to the description of genus Enaphalodes at the Genera of Elaphidiini site: mesofemoral shape linear... Anelaphus generally have gradually enlarged femora (sometimes mildly clavate profemora), while Enaphalodes has linear femora.

(The femur, plural femora, is usually the thickest segment of a beetle's leg. Usually the femur, tibia, and tarsus, in that order, are visible from above.)
