Genus: Eucicones

Diagnostic Features
  • Description: Antennae 10-segmented with a distinct, 1-segmented club. Antennal setation sparse. Subantennal grooves present, as long as eyes. Eyes large, well-developed, facets moderately coarse. Pronotal disc convex, simple. Lateral pronotal margins widest posteriorly, distinctly explanate. Procoxal cavities open. Metacoxae narrowly separated, separation less than metacoxal length. Elytra variegated, multi-colored. Elytral margins slightly explanate. Tarsal formula 4-4-4. Dorsum with short, thick, flattened, club-shaped setae.
  • Similar genus/genera: The genus Eucicones is similar in general appearance to the genus Acolobicus. The presence of faint carinae on the pronotal disc, lack of thick, flattened, club-shaped setae and unicolored dorsal surface serve to distinguish Acolobicus.
Known Distribution
  • Northeast (DC, NJ, PA), North Central (IL, IN, KS, MO), Southeast (TN, AL, FL), South Central (OK, TX) USA, and Ontario, Canada.
Biology
  • Eucicones marginalis has been collected from under the bark of dead oaks and elms.

  • Abundance: Uncommon.
