4′. Gena short (GL: FH ♂ 0.16–0.25; ♀ 0.20– 0.29, Fig. 7G, I ); thoracic sternite pubescence moderately dense, abdominal sternite pubescence sparse, suberect to erect, not obscuring surface; abdominal punctation oval to round with anterior edges at most slightly raised, medium to large, sparse, punctures separated by>2X puncture diameter; abdominal microsculpture transverse, sparse, lightly to moderately impressed; abdominal surface glossy ( Fig. 8G, H, I, J )...........................................6

5. Pronotum with short median, inconspicuous, slightly elevated, keel lower than dorsolateral tubercles and limited to posterior half of disk ( Fig. 6C ); punctures of metafemoral club small, basal edges slightly raised, surface appearing minutely roughened; metafemoral club abruptly widened towards apex forming distinct apical club ( Fig. 6H ); at least metafemur and metatibia bicolored, pedicel yellow with apex brown to black ........................ C. fuscipennis (LeConte)

5′. Pronotum with well-developed, strongly elevated, median keel as tall as dorso-lateral tubercles and extending from anterior sulcus to the posterior sulcus ( Fig. 6F ); punctures of apex of metafemur large, basal edges strongly protuberant, surface appearing coarsely roughened; metafemur gradually widened towards apex ( Fig. 6I ); all legs brown to black ...................... .............................................. C. gracilis Brullé

6. Color lighter, elytra light to dark brown, rarely black; all femora bicolored with sharp transverse line of demarcation between yellow pedicel and dark apical club; metafemoral club less elongate (L:W ♂ 2.33–2.48; ♀ 2.25– 2.41, 95% confidence, Fig. 9C ); antennomere 9 elongate (L:W ♂ 4.02–4.36; ♀ 3.56–3.77, 95% confidence, Fig. 6J ); female mesofemoral club somewhat short (L: W 1.81 –2.49, 95% confidence, Fig. 9A )......................................... ............
