Description and Taxonomy
Length 5-7mm. In addition to tribal characters (prominent lateral pronotal ridges, notosternal antennal grooves, deep pits near procoxae) the genus may be diagnosed by biserrate (in females) or bipectinate (in males) antennae. The genus is monotypic in the Nearctic Region (Muona 2000).
Life History
This is the rarest eucnemid in the GSMNP. A few specimens were collected with Malaise traps at Twin Creeks ATBI plot. They were found from late June to late August at 625 m elevation. Although it's widespread North American species, the only one host genus is known, i.e. Populus ( Muona 2000).
Distribution
Widespread in North American, known from British Columbia and Ontario to California, Texas and Virginia. Most of known records involve single specimens (Muona 2000).
Conservation Concerns
Not under threat.
